Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gesture detection sensors are cumbersome and not hygienic, as they require a glove-like form that encloses the hand, limiting convenience and hygiene in gesture input systems, especially in diverse digital environments like VR and AR.
Innovation Solution
A detachable gesture detection sensor system comprising a skin-conformable base sheet with integrated sensing parts and electrode patterns, connected to a reader module that can be easily attached to the back of the hand, allowing for precise measurement of finger movements and gestures, and a computing device for recognizing gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a glove-like detection sensor is used to enclose the hand, then gesture detection functionality is achieved, but convenience and hygiene are deteriorated
Solution Approach 1:
The detection sensor is divided into two separate components: a disposable base sheet with sensing parts that contacts the skin, and a reusable reader module that processes signals. This segmentation allows the base sheet to be easily detached and replaced for hygiene purposes, while the reader module maintains functionality across multiple uses.
Solution Approach 2:
The base sheet is designed as a disposable component that can be easily attached and removed from the hand. After use, it can be discarded, eliminating the need for cleaning or sterilization of the portion that contacts the skin, thus improving hygiene while maintaining gesture detection functionality.
2Adaptability or versatility
If a glove-like detection sensor is used to enclose the hand, then gesture detection functionality is achieved, but device complexity is increased
Solution Approach 1:
The system is segmented into a simple base sheet containing only sensing elements and a separate reader module containing processing electronics. This division reduces the complexity of each individual component compared to a fully integrated glove, while maintaining overall functionality.
Solution Approach 2:
The complex electronic processing components are extracted from the base sheet and placed in a separate reader module. This leaves the base sheet with only simple sensing elements, significantly reducing its structural complexity and making it easier to manufacture and dispose of.
3Ease of operation
If a disposable base sheet with sensing parts is used, then hygiene and convenience are improved, but manufacturing precision requirements are increased
Solution Approach 1:
Multiple sensing parts are merged onto a single flexible base sheet, allowing them to be manufactured together as one integrated component. This approach maintains hygiene and convenience benefits while managing manufacturing precision requirements through unified production processes.
