Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two sets of switch circuits are used with four triodes, then the lamp controller can control two circuits of load, but the lamp luster quantity connected is limited and the lighting effect is restricted
Solution Approach 1:
The switch unit is divided into three independent switch circuits, each capable of controlling one circuit of load. This segmentation allows the controller to connect and control multiple lamp lusters independently, increasing the lamp luster quantity connected while maintaining manageable circuit complexity through modular design
Solution Approach 2:
Each switch circuit is designed with universal functionality to control one circuit of load, allowing the same circuit structure to be replicated three times. This multi-functional approach enables the controller to handle three separate lamp lusters with identical control mechanisms, expanding adaptability without proportionally increasing complexity
2Reliability
If two sets of switch circuits are used, then alternate flashing of two circuits can be realized, but when one switch circuit is damaged the overall performance deteriorates
Solution Approach 1:
The three switch circuits are designed as independent segmented units, each capable of operating autonomously. This segmentation ensures that damage to one circuit does not affect the others, maintaining system reliability while preserving lighting effects through the remaining functional circuits
Solution Approach 2:
The controller incorporates redundant switch circuits beyond the minimum required for basic functionality. This prior cushioning through redundancy ensures that if one circuit is damaged, the system can continue operating with reduced but still effective lighting performance, maintaining reliability
3Ease of manufacture
If four triodes are used to form two sets of switch circuits, then switching function is achieved, but the circuit structure becomes complex with more wiring and increased cost
Solution Approach 1:
The switch circuits are designed with localized functional units where each triode and its associated components form a self-contained switching module. This local quality approach allows for standardized manufacturing of each module, reducing overall manufacturing cost while simplifying the circuit structure through modular assembly
Solution Approach 2:
Instead of using a complex integrated switching mechanism, the patent inverts the approach by using multiple simple, identical triode-based switch circuits. This inversion from complex-to-simple strategy reduces manufacturing cost and simplifies the overall circuit structure while achieving the required switching functionality
4Ease of operation
If only one triode in each switch circuit is controlled by the control module, then control is simplified, but the other triode cannot be controlled independently
Solution Approach 1:
The control module is segmented to provide independent control signals to each triode in the three switch circuits. This segmentation enables each triode to be controlled independently while maintaining simplified control through a unified control module architecture, balancing control efficiency with independent control capability
Solution Approach 2:
The control module dynamically adjusts the control signals sent to each triode based on the desired lighting effects. This dynamic control allows each triode to be independently controlled when needed while maintaining simplified operation through automated control sequences, achieving both control efficiency and independent control capability
