Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mechanical buttons or sensing blocks are used to generate control instructions, then the control functionality is sufficient, but the operating interface occupies more space and flexibility is limited
Solution Approach 1:
The patent combines multiple sensing methods (touch sensing and pressure sensing) into a single sensing block, allowing one sensing block to generate multiple control instructions. This merging approach reduces the number of sensing blocks needed from four to two, thereby reducing the operating interface area while maintaining full control functionality.
Solution Approach 2:
Each sensing block is designed to perform multiple functions by integrating both touch sensing and pressure sensing capabilities. A single sensing block can generate different control instructions (volume up/down, song selection) depending on whether it detects a touch event or a pressure event, making it a multi-functional component that replaces multiple dedicated buttons.
2Adaptability or versatility
If four sensing blocks are configured to generate four control instructions, then all control functions are available, but the device complexity increases
Solution Approach 1:
The patent merges touch sensing and pressure sensing functions into the same sensing block structure. The driver periodically provides power to both driving lines, and the receiver processes signals from both sensing lines within a single sensing block, reducing the total number of sensing blocks from four to two while maintaining the ability to generate four different control instructions.
Solution Approach 2:
The driver is configured to periodically and un-simultaneously provide power to the first and second driving lines. This periodic action allows the system to multiplex the sensing blocks, using the same physical block for different sensing functions at different time intervals, thereby reducing hardware complexity while maintaining full functionality.
