1. Research Background and Purposes

With technology developing rapidly, people have relatively high demand for food. To prepare cuisine with great look and taste, cutting board is one of the essential tools for cooking. Based on the opinions above, a "multi-purpose cutting board" was invented which not only maintain traditional cutting board's function of chopping food but protect kitchen counter or table from scratches. Additionally, in combination with the storage and dispensing concepts, when using the product, users can easily place the chopped food materials into drawers to remove the limitation of insufficient space or prevent different food materials from mixing together in the same dish while the auxiliary cooking design offer convenience to users in using peeler in the process. The product brings about various benefits and improves the defects of traditional cutting board.

Traditional cutting board has simple structure as well as function as a board for chopping food materials that are usually placed in various dishes and placed on the kitchen counter. Since the space of modern kitchen is limited, it is relatively inconvenient when a number of dishes are placed on the kitchen counter. To improve the cooking environment and solve the problem of placing an excessive number of dishes in such limited space, the invention is a further improvement of traditional cutting board which improves the structure and repairs the defects of traditional cutting board. With the "innovative" and "creative" design, it is a practical product of diverse functions that raises space utilization in order to minimize the inconvenience in cooking.

When chopping, the water of food materials is likely to flow onto the kitchen counter, making the surface damp and dirty and requiring plenty of time in follow-up cleaning so that the kitchen can remain clean and tidy. Meanwhile, multiple dishes are required to hold the food materials after processing, which occupy the space of kitchen. However, due to the simple design of peeler, it is difficult to collect food materials after peeling, resulting in waste of food.

Therefore, with the innovative design of "multi-purpose cutting board", the body of the cutting board and the auxiliary cooking appliance are equipped with storage interlayers and water pans. The interlayers are used for adjusting storage space according to user's requirements so that the chopped or peeled food materials can be further classified and stored in drawers. The food materials can be easily taken from the drawers for cooking. Besides, the storage layers have multiple small holes at the bottom to drain the excess water of foods and avoid germs due to improper reservation of food materials.

At present, traditional cutting boards in the market are made of a variety of materials that fit different cooking methods and food materials. On that basis, each household often has one or two types of cutting boards for alternative use, occupying space and making the kitchen cramped with dishes filled with chopped food materials.

Since ancient times, cutting board has always been an essential tool for household. However, the dull and inflexible use of cooking tools inevitably makes people feel restless for cooking in the hustle and bustle of modern life. With the creative design of multi-purpose cutting board, the multifunction and diversified combination is expected to add enjoyment of cooking in life.

2. Literature Review

In daily life, cutting board is not merely a tool for chopping food materials. The invention is expected to offer convenience of storage and save space of kitchen in the modern society and through combination with storage drawers as well as auxiliary cooking tools, further avoid placing an excessive number of dishes to hold food materials, address the difficulties in finding cooking materials and relieving the damp and disorder situation of chopping in order to improve the overall environment of kitchen in respect of cleanliness, tidiness and comfortableness and make the best of space utilization.

2.1. Basis of Innovation

Inventions are solutions to inconvenience in life. Therefore, creative invention is required to jump out of the existing box, get rid of the existing limitations of logical thinking and make innovative attempts by close observation of details in daily life, different views of matters and development of unique and creative ideas to eventually produce inventions for the convenience and betterment of life. Creativity is a process of reconstruction of ideas originating from your existing perceptions to change the existing subjects, making them increasingly interesting. The inherent difference between human beings and other creatures lies in the fact that human beings are able to make good application of their thinking ability as well as creativity to continuously produce new inventions for betterment through numerous attempts. In fact, almost all great works come into being because of the inconvenience and inspiration in life (Weng, 2011).

The English term "innovation" originates from Latin with three layers of original connotation: renewal, meaning change of the original; creation of something new, meaning creation of something that does not exist before; change, meaning development or renovation of the original. Product innovation can be defined as development of products showing the characteristics of innovation, value, practicability, suitability or other significance. Innovation is defined on the basis of comparison between such products and the existing similar ones while value is defined on the basis of benefits or significance of such products to a certain group of people (Liu, 2011).

Previous studies on product innovation mainly focused on enterprises of developed countries. Considering the current changing global economic environment in the era of globalization, enterprises are pursuing innovation and breakthroughs and the emerging economies are part of the important economic force. In such situation, enterprises tend to concentrate themselves on active attempts to achieve innovation and seek new way to success and development. Because there is a wide range of product innovation of emerging economies and the "BRIC" countries, namely China, India, Russia and Brazil, are situated in Asia, Taiwan has the best geographical location standing next to the emerging markets and having good technology for independent development and innovation of enterprises thanks to the favorable management advantage as the foundation for innovation (Teng and Hsu, 2015).

The creative product, "multi-purpose cutting board", is an improvement in structural defects of the existing cutting board. It is an invention that facilitates cooking with appropriate space utilization, convenient storage of food materials and diverse functions, offering a new option for dining teachers in accordance with economic benefits, reduction of costs and practical value as the concept and goal of the invention.

2.2. Relevant Studies on Cutting Board

Cutting board is one of the important tools for cooking. Cutting boards are made of wood, plastic, bamboo or tempered glass. Cutting boards made of different materials have their own advantages and disadvantages. An introduction of common cutting board materials is provided as follow:

2.2.1. Wooden Cutting Board

Wooden cutting board is the most commonly used product. It is usually relatively heavy and has strong tenacity, making it an ideal option for cutting meat and bones. Generally speaking, the wood that only goes through simple processing before it is put into production of cutting boards is likely to breed bacteria and have cracks as well as wood chips.

(1) Advantage: Suitable for chopping and cutting foods (e.g. preparing fish or meat dishes).

(2) Disadvantage: Easy to get mildewed and have filth, relatively heavy.

2.2.2. Plastic Cutting Board

Plastic cutting board is light, easy to clean, convenient for storage and excellent in mold resistance. However, it cannot resist high temperature and easily gives away to pressure. There are two types of plastic cutting boards respectively made of PE and PP materials. The PE cutting boards have different colors. Thicker ones are combination of multiple layers. These cutting boards are cheaper. In contrast, PP cutting boards have higher density and all are one-piece cutting boards only in white and more expensive than the PE materials.

(1) Advantage: Easy to clean, relatively light.

(2) Disadvantage: Easy to slide.

2.2.3. Tempered-glass Cutting Board

Tempered-glass cutting board is not applicable to chopping vegetables and meat but suitable for cutting fruits and bread; the cutting board has nice appearance and can be directly used as a tray to serve guests after cutting. Glass cutting boards generally have small patterns to prevent food materials from sliding.

(1) Advantage: Suitable for cutting fruits without scratches, easy to clean.

(2) Disadvantage: High rigidity, easy to damage knives in case of chopping.

2.2.4. Bamboo Cutting Board

Except cutting or chopping hard, bamboo cutting board is recommended because compared to wooden cutting board, it is easier to clean and not likely to go mildewed or have cracks and it is lighter than wooden cutting board.

(1) Advantage: Easy to clean, high temperature resistance, not easy to crack compared to wooden cutting board.

(2) Disadvantage: Relatively high rigidity, making loud noise when in use, easy to damage knives; since bamboo is relatively thin, some products may have plenty of gaps that are easy to breed bacteria.

Most people take "material" as the first priority when purchasing cutting boards. Different materials are applicable to different occasions and users should purchase cutting boards according to the characteristics of food materials and their cooking demands (iRead, 2016). Users had better select cutting boards based on their cooking habits and frequency. For those cooking at home every day, wooden cutting board is the best option while for those frequently eating out and only cutting fruits or preparing simple meals at home, plastic or tempered-glass cutting board is an ideal choice (4F Cooking Home, 2012).
