Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple game controllers are used to support sophisticated gaming inputs, then gaming input capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal remote control device that can perform multiple functions: it serves as both a traditional remote control for A/V equipment and a gaming controller. The touch-sensitive panel enables the same device to handle both remote control operations and gaming inputs, eliminating the need for separate specialized controllers and reducing overall system complexity.
Solution Approach 2:
The patent combines the remote control functionality and gaming controller functionality into a single integrated device. The touch-sensitive panel serves dual purposes: navigating menu systems for A/V equipment and providing gaming inputs, thereby merging two previously separate functions into one unified controller.
2Ease of operation
If traditional remote controls are used for A/V equipment, then remote control operation is achieved, but user-specific customization and efficient input are limited
Solution Approach 1:
The touch-sensitive panel provides real-time feedback by detecting the position, pressure, and movement of the user's finger. This feedback mechanism enables the system to distinguish between different user interactions (hovering, tapping, pressing) and accordingly provide customized responses, thereby enhancing both ease of operation and adaptability to user-specific preferences.
Solution Approach 2:
The patent utilizes changes in physical parameters of the touch-sensitive panel (capacitance, impedance) to detect user interactions. By monitoring these parameter changes, the system can identify different user actions and provide customized operational modes, enabling both efficient input and user-specific adaptation within a single device.
3Ease of operation
If touch-sensitive pads detect hovering fingers with three-dimensional position data, then user identification and intuitive input are improved, but measurement complexity increases
Solution Approach 1:
The patent replaces complex mechanical sensing systems with electrical field-based touch-sensitive panel technology. Instead of using multiple sensors and complex algorithms to detect three-dimensional finger position, the system uses changes in electrical properties (capacitance, impedance) of the touch-sensitive panel to directly measure finger position, pressure, and movement, thereby simplifying the detection mechanism while maintaining measurement accuracy.
