高齡化社會的來臨造成輔具需求量增加。輔具價格差距甚大，政府雖然對輔具的購買有提供補助，但如果要購買好的產品，仍須自行負擔一部份的費用，所以經濟能力較不足的家庭往往無法購買品質良好的輔具。此外，因為輔具的使用年限較長，使用輔具的老年人一旦往生，家中的閒置輔具反而造成了空間浪費。本研究針對上述問題，設計了「輔助你我他」輔具交易平台。本平台以App為介面，銷售方必須將成交的輔具送至平台進行檢測後，始由平台運送至購買方。另一方面，本研究亦希望利用循環經濟的方式為閒置的輔具創造使用價值，讓許多有類似困擾的家庭能獲得便宜又質佳的輔具，也讓沒有在使用的輔具不會閒置。

The advent of an aging society has caused an increase in the demand for assistive devices. There is a big gap in the price of assistive devices. Although the government provides subsidies for assisted purchases, if you want to buy good products, you still have to bear part of the cost yourself. Therefore, families with less financial means often cannot buy good-quality assistive devices. In addition, because assistive devices have a long service life, once the elderly who use assistive devices die, the idle assistive devices at home will cause a waste of space. In response to the above-mentioned problems, this research has designed a "Help Every One" auxiliary tool trading platform. This platform uses the App as the interface, and adopts the O2O business model that the seller must send the transaction aids to the platform for testing, and then the platform will ship to the buyer to ensure quality. On the other hand, this research also hopes to use the circular economy method to create use value for idle assistive devices, so that many families with similar problems can obtain cheap and high-quality assistive devices.
