Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired communication is used to control lights through video content, then lighting control is achieved, but implementation becomes difficult and flexibility is reduced
Solution Approach 1:
The patent replaces wired mechanical communication with wireless communication technology. The lighting control system uses wireless signals to transmit control instructions from the terminal device to the lighting device, eliminating the need for physical wiring and HDMI parsing hardware. This substitution achieves the same lighting control function while dramatically improving ease of operation and reducing implementation complexity.
2Adaptability or versatility
If Philips' hue system with Zigbee wireless control is used, then wireless lighting control is achieved, but compatibility is limited to only Philips lights and requires a special video linkage bridge
Solution Approach 1:
The patent implements a universal lighting control system where a single terminal device can control multiple brands of Zigbee lighting devices. The system uses standard Zigbee communication protocols and eliminates the need for brand-specific bridges. The terminal device directly communicates with various Zigbee lights (Philips, Greta, Yeelight, etc.) through wireless communication, achieving multi-brand compatibility without requiring specialized bridging hardware.
3Ease of operation
If Philips' hue system is used, then video linkage control is achieved, but cost increases due to requiring a special video linkage bridge
Solution Approach 1:
The patent extracts and removes the specialized video linkage bridge component from the system. Instead of requiring a separate bridge device to enable video linkage between the terminal and lighting devices, the system integrates this functionality directly into the terminal device. The terminal device uses its built-in camera and processor to capture video content and generate lighting control instructions, which are then transmitted wirelessly to the lighting devices, eliminating the need for additional bridge hardware and reducing system cost.
