Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless dimmers use integrated circuits with various functions, then dimming control precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the wireless dimmer into separate functional modules: a radio signal control module for receiving and processing wireless dimming signals, and a separate driver module for controlling the LED lamp. This segmentation allows each module to be optimized independently, reducing overall system complexity while maintaining precise dimming control through dedicated signal processing circuits.
Solution Approach 2:
The patent extracts the radio signal control functionality from the traditional integrated circuit into a separate radio signal control module. This extraction simplifies the main driver circuit by removing complex integrated circuits, while the separated module handles wireless signal processing independently, thus reducing overall device complexity while preserving dimming precision.
2Measurement precision
If wireless dimmers use integrated circuits with various functions, then dimming control precision is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the wireless dimmer into separate modules (radio signal control module and driver module), the patent enables independent manufacturing and assembly of simpler components. This reduces the need for expensive multi-functional integrated circuits, lowering manufacturing costs while maintaining precise dimming control through dedicated signal processing in each module.
Solution Approach 2:
The patent extracts the expensive integrated circuit functionality into a separate radio signal control module that can be manufactured independently using simpler, more cost-effective components. This extraction allows the main driver circuit to use less expensive elements, overall reducing manufacturing cost while preserving precise dimming control capabilities.
3Adaptability or versatility
If wireless dimmers use integrated circuits, then control functionality is improved, but PCB space and part size increase
Solution Approach 1:
The patent segments the control functionality into a separate radio signal control module with its own dedicated circuit board, physically separating it from the driver module. This segmentation allows each module to use minimal PCB space optimized for its specific function, reducing the total PCB area required compared to a single large integrated circuit board housing all functions.
Solution Approach 2:
The patent extracts the radio signal control functionality from the main driver PCB into a separate module with its own compact circuit board. This extraction reduces the PCB space required in the main driver unit, as the extracted module can be implemented with more space-efficient, purpose-built circuitry optimized for wireless signal processing.
