Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed input panel layout is used, then device complexity is reduced and ease of manufacture is improved, but adaptability to different users and input accuracy deteriorate
Solution Approach 1:
The system performs preliminary actions by capturing hand shape images and analyzing touch point data before generating the personalized input panel. This preprocessing of user biometric data enables the subsequent automatic generation of customized key layouts without requiring complex real-time adjustments during actual input operations.
Solution Approach 2:
The system changes physical parameters of the input panel by adjusting key positions, sizes, and distributions based on extracted hand shape features. The key layout parameters are dynamically modified according to measured hand dimensions, finger lengths, and touch patterns, transforming a fixed layout into an adaptive one.
2Measurement precision
If hand shape analysis is implemented, then input accuracy is improved, but measurement precision requirements and device complexity increase
Solution Approach 1:
The system creates a digital copy of the user's hand shape through image capture and processing. Instead of requiring complex physical measurement devices, the patent uses optical imaging to replicate hand geometry in digital form, which can then be analyzed through software algorithms to extract relevant biometric features for input panel customization.
