Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a static control system is used to control LEDs, then the emission amount per unit time of each LED can be increased, but the number of wires and power consumption are increased
Solution Approach 1:
The patent segments the LED control into two distinct control systems: a static control system for LEDs requiring high emission amounts and a dynamic control system for LEDs requiring flexible timing control. This segmentation allows each system to be optimized for its specific requirements, preventing the need to use static control for all LEDs and thus reducing the overall number of wires required.
Solution Approach 2:
The patent introduces a dynamic control system that allows flexible timing control of LEDs through sequential activation. This dynamic approach enables the system to adapt to different control requirements and reduce wire usage in scenarios where high emission amount is not the primary requirement.
2Quantity of substance
If a dynamic control system is used to control LEDs, then the number of wires can be reduced, but the emission amount per unit time of each LED is limited
Solution Approach 1:
The patent divides the LED control into static and dynamic systems, allowing high-emission LEDs to use the static control system with dedicated wires while low-emission or timing-critical LEDs use the dynamic control system with shared wires, optimizing the balance between wire count and emission capability.
Solution Approach 2:
The patent applies different control qualities to different LED groups: static control quality for LEDs where high emission amount is critical, and dynamic control quality for LEDs where timing flexibility is more important. This local differentiation allows the system to achieve high emission amounts where needed without unnecessarily increasing the overall wire count.
3Adaptability or versatility
If both static and dynamic control systems are used in the same game machine, then flexible control for different LED arrangements is achieved, but the design of the performance control circuit becomes complicated and calculation load increases
Solution Approach 1:
The patent designs a unified light source control device that can operate in both static and dynamic control modes, making it a multi-functional device. This universality allows the same device to control different LED arrangements without requiring separate control circuits for each mode, thereby reducing overall system complexity despite the added versatility.
Solution Approach 2:
The patent introduces a light source control device as an intermediary between the performance control circuit and the LEDs. This intermediary handles the complexity of both static and dynamic control systems, shielding the performance control circuit from the intricacies of LED control and reducing its calculation load while maintaining flexible control capabilities.
4Illumination intensity
If the number of LEDs is increased to enhance performance effect, then visual appeal is improved, but the number of wires and terminals increases and installation becomes difficult
Solution Approach 1:
The patent segments LEDs into groups controlled by either static or dynamic control systems. This segmentation enables modular installation and wiring, where large numbers of LEDs can be managed through organized groups rather than individual wire connections, significantly improving ease of installation while maintaining high performance effects.
