Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lens is added to cover the entire LED array to control directionality, then light direction control is improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the LED array into multiple independently controllable LED modules, each with its own adjustable gimbal mechanism. This segmentation allows individual LED modules to be directed independently, achieving precise beam pattern control without requiring a complex lens system to cover the entire array.
Solution Approach 2:
The patent employs gimbal mechanisms that enable dynamic adjustment of each LED module's orientation. This dynamic positioning capability allows the LED modules to be directed at different angles and positions, providing flexible beam pattern control without the need for fixed lens systems.
2Ease of operation

Solution Approach 1:
The patent divides the LED array into multiple independently controllable LED modules, each with its own adjustable gimbal mechanism. This segmentation allows individual LED modules to be directed independently, achieving precise beam pattern control without requiring a complex lens system to cover the entire array.
Solution Approach 2:
The patent replaces the optical lens system with a mechanical gimbal-based positioning system. Each LED module is mounted on a gimbal that allows mechanical adjustment of its orientation, substituting the need for complex optical direction control with simpler mechanical positioning.
3Ease of operation
If LED array is positioned to direct light in specific direction, then light directionality is improved, but heat dissipation becomes difficult
Solution Approach 1:
The patent designs the gimbal mechanism to perform multiple functions: it positions the LED modules for optimal light direction while simultaneously maintaining proper orientation of the heat sink for efficient heat dissipation. The heat sink is configured to always face the desired heat dissipation direction regardless of the LED module's light-emitting orientation.
Solution Approach 2:
The patent separates the light emission direction from the heat dissipation direction by utilizing different spatial dimensions. The gimbal mechanism allows the LED module to be oriented in one direction for light emission while the heat sink is positioned in another dimension (perpendicular or opposite orientation) to optimize thermal management independently of the light direction.
4Ease of manufacture
If conventional mounting is used for LED array, then connection is simple, but positioning precision and direction control are insufficient
Solution Approach 1:
The patent employs gimbal mechanisms that enable dynamic adjustment of each LED module's orientation. This dynamic positioning capability allows the LED modules to be directed at different angles and positions, providing flexible beam pattern control without the need for fixed lens systems.
