Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing key cap structure on electronic terminals is bulky and protruding, hindering a compact and seamless design, leading to complexity and a lack of integrity in the device's appearance.
Innovation Solution
The implementation of a virtual key system at the edge of the terminal shell, utilizing a sensor and touch mark, which eliminates the need for a key cap and metal dome, allowing for a more integrated and user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a key cap and metal dome structure is used, then the key operation function is achieved, but the terminal appearance becomes complex and lacks integrity
Solution Approach 1:
The patent extracts and removes the key cap structure from the terminal, eliminating the protruding external component while retaining the essential key operation function through an integrated sensor design embedded within the terminal body
Solution Approach 2:
The patent merges the key operation function directly into the terminal shell by integrating the sensor within the terminal body, combining the housing and input mechanism into a unified structure that maintains appearance integrity while preserving functionality
2Ease of operation
If a key cap structure is used, then the key operation function is achieved, but the terminal design becomes non-compact
Solution Approach 1:
The patent removes the external key cap structure that occupied additional space, eliminating the need for pressing stroke clearance and achieving a more compact terminal design while maintaining key operation capability through the integrated sensor
Solution Approach 2:
The patent transitions from a three-dimensional protruding key cap structure to a two-dimensional integrated sensor surface, eliminating the depth dimension occupied by the key cap and metal dome assembly, thereby achieving greater compactness
