Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple external devices (set-top boxes, DVD players) are connected to the TV set through separate interfaces, then each device can be controlled independently, but the device complexity and wiring complexity increase significantly
Solution Approach 1:
The patent merges multiple external devices (set-top boxes, DVD players, etc.) into a single integrated extension module that connects to the TV set through one unified interface. This consolidation reduces the number of separate connections and interfaces needed, thereby simplifying wiring complexity while maintaining the ability to handle multiple signal sources through a standardized connection protocol.
Solution Approach 2:
The extension module is designed with universal functionality to accommodate multiple types of signal sources through a single standardized interface. It provides multi-functionality by supporting various device types (digital TV, analog TV, DVD, VCD, etc.) and signal formats within one module, eliminating the need for device-specific connections and reducing overall system complexity.
2Adaptability or versatility
If each external device has its own power supply, then each device can operate independently, but the device complexity and number of components increase
Solution Approach 1:
The patent consolidates multiple separate power supplies into a single unified power supply system within the extension module. This single power supply unit provides electrical power to all connected external devices through the module's internal distribution network, reducing the total number of power supplies from multiple individual units to one centralized unit, thereby simplifying the system while maintaining independent device operation capabilities.
3Ease of operation
If multiple remote controllers are used for different devices, then each device can be controlled precisely, but the ease of operation decreases due to the need to manage multiple controllers
Solution Approach 1:
The extension module incorporates a universal remote control system that can control multiple different types of external devices through a single remote controller. This universal controller communicates with various devices (set-top boxes, DVD players, etc.) through standardized protocols, providing precise control functionality for all devices while eliminating the need for users to manage multiple separate remote controllers.
4Adaptability or versatility
If combined TV sets integrate multiple functions (DVD, DVB, IP TV), then the adaptability increases, but the ease of manufacture and standardization become difficult
Solution Approach 1:
The patent segments the integrated functionality into a separate, standardized extension module that can be attached to the TV set. This modular segmentation allows the core TV set to maintain standardization and simple manufacturing processes, while the extension module provides the integrated functions (DVD, DVB, IP TV, etc.) through a standardized interface. The segmentation enables independent manufacturing and testing of the extension module, making it easier to produce and replace without affecting the main TV set production line.
