Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices are limited by single-function keys, which do not meet the increasing demand for lightweight and multifunctional designs.
Innovation Solution
An electronic device and key module that incorporates a slidably positioned key plate, a switch, and a location sensor, where the processor performs different commands based on the key plate's location, enabling a single key to execute multiple functions by sending distinct switch signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple keys are used to provide multiple functions, then the functionality is improved, but the device size and weight increase
Solution Approach 1:
The patent implements a single key capable of performing multiple functions by detecting different pressing depths. The key structure includes a key plate that can be pressed to different depths, with a first depth triggering a first function and a second depth (greater than the first) triggering a second function. This multi-functional design eliminates the need for multiple separate keys, thereby reducing device weight while maintaining versatility.
Solution Approach 2:
The patent applies dynamic characteristics to the key by enabling it to perform different functions based on the degree of pressing. The key plate is configured to be pressed to a first depth or a second depth greater than the first depth, with each depth level corresponding to different functions. This dynamic response to varying pressing depths allows a single key to provide multiple functions without increasing device weight.

3Volume of moving object
If a single key is used for multiple functions, then the device size is reduced, but the key complexity increases
Solution Approach 1:
The patent applies dynamic characteristics to the key by enabling it to perform different functions based on the degree of pressing. The key plate is configured to be pressed to a first depth or a second depth greater than the first depth, with each depth level corresponding to different functions. This dynamic response mechanism allows a single key to provide multiple functions with relatively simple structural modifications, avoiding the need for complex multi-key configurations.
