Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart watches face challenges in providing effective user interaction due to their small display size, making traditional touch screen input methods inconvenient for typing and navigation.
Innovation Solution
A wearable device with a band equipped with sensors and signal generators that detect changes in shape or position, allowing for alternative input methods such as shape-based interactions and relative position sensing to automate functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional touch screen interaction is used in smart watches, then the device can provide input functionality, but the small display size makes typing and navigation inconvenient
Solution Approach 1:
The patent moves the interaction interface from the two-dimensional small display screen to the one-dimensional band structure, utilizing the spatial extent of the band along the wrist to provide a larger effective interaction area. The band can be manipulated along its length to provide input functionality that is more convenient than touching a small screen.
2Ease of operation
If the band includes sensors and signal generators to detect shape and position changes, then user interaction convenience is improved, but device complexity increases
Solution Approach 1:
The band is designed to serve multiple functions: it provides structural support for wearing the device, contains sensors for detecting shape and position changes, includes signal generators for communication, and acts as the interaction interface itself. This multi-functionality reduces the need for separate components and justifies the increased complexity by delivering substantial operational convenience.
