Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple touch sensors are added to enable additional input functionality, then user input flexibility and operational control are improved, but device complexity increases
Solution Approach 1:
The patent divides the touch sensing functionality across multiple independent touch sensors located on different surfaces of the device (front, back, sides). Each touch sensor can be independently controlled and processed, allowing the system to manage complexity by handling inputs from each sensor separately while providing comprehensive multi-surface input capability.
Solution Approach 2:
The patent implements a universal input processing system that handles touches from multiple sensor locations through a common processing framework. The same processor and software architecture manage inputs from front touchscreen, back surface, and side surfaces, creating a unified multi-functional input system that improves versatility without proportionally increasing complexity.
2Ease of operation
If touch sensors on rear and side surfaces are activated for input, then ease of operation is improved through one-handed use, but difficulty of detecting and measuring inputs increases
Solution Approach 1:
The patent applies different detection characteristics to different touch sensor locations. Each touch sensor (front, back, sides) can be configured with location-specific sensitivity and detection parameters optimized for its position and intended use case, allowing accurate detection despite varying operational conditions at each surface.
Solution Approach 2:
The system incorporates feedback mechanisms where touch inputs from multiple surfaces are processed and correlated. The processor analyzes touch patterns, locations, and sequences across all sensors to distinguish intentional inputs from noise, improving detection accuracy through contextual feedback from the overall input pattern.
