應用TRIZ理論實作一個具RAID功能之USB磁碟擴充裝置

A Study of USB Disk Expansion Device with RAID Applying TRIZ Theory

在台灣，曾經每兩人就有一人使用過隨身碟，而使用量高的主要原因是：裝置攜帶方便、價格便宜等，但隨身碟在使用上依然有許多不便之處，如：必須插入電腦才可以存取資料、資料儲存量過小（一般遠小於硬碟）、隨身碟時常會因主板的晶片故障或病毒攻擊導致資料容易遺失。另一方面，因雲端技術的發展，使得隨身碟的使用率大幅下降，因此本研究將使用TRIZ發明問題解決理論，運用TRIZ所提供的39項工程參數、矛盾矩陣、40項發明原則，來解決上述隨身碟在使用上的缺點。經透過39項工程參數分析後，將問題點套用於矛盾矩陣中，得出的6項發明原則中找出有關上述問題的創新解決方案，並進一步的設計出無線隨身碟擴充裝置，裝置透過無線的方式存取隨身碟內的資料，加快資料更新的速度，架設RAID，可將多個隨身碟的存取空間合併，使得資料的存取空間擴充性增加。這個RAID裝置當然也具備資料自動備份的功能，解決單一隨身碟資料容易遺失的問題，更進一步保障資料的安全性，及活化隨身碟的使用率，並且隨身碟擴充裝置相比傳統NAS，數據傳輸速度更快、架設成本更低、體積更小。本研究所提出的無線隨身碟擴充裝置已申請並獲得專利，在2020KIDE高雄發明展亦獲得金牌殊榮。

There are many shortcomings to using USB disks. For example, they must be used by the computer. The storage space of USB disks are usually small (much smaller than the hard disks). Moreover, USB disks are prone to chip failure and virus attack, which can easily cause data loss, and the lost data cannot be retrieved, etc.
Therefore, we use the TRIZ invention problem-solving theory to solve the shortcomings of using USB disks. First, we analyze the specific problem with 39 engineering parameters, put these parameters into the contradiction matrix, and find innovative solutions to the above problems from the six invention principles obtained.
According these principles, we have developed a USB disk expansion device. USB disks can read/write data through wireless network by using the USB disk expansion device. Moreover, multiple expansion devices can cooperate to establish a RAID system. We estimate the data transmission speed, price, and volume of USB disk expansion devices, comparing with traditional NAS, are more efficiently.
Finally, the proposed USB disk expansion device obtained a patent from IPO R.O.C, and a gold medal award from 2020 KIDE.
