Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an LED array is used to increase luminous flux output, then the luminous flux output is improved, but the volume of the light source system becomes excessively large
Solution Approach 1:
The patent combines LED arrays and laser diode arrays into a hybrid light source system. The LED array provides high luminous flux output while the laser diode array contributes high brightness and directionality, achieving synergistic effects that increase overall luminous flux without proportionally increasing system volume.
Solution Approach 2:
The patent introduces a moveable optical block that can dynamically adjust the light path and focus characteristics of the hybrid light source. This dynamic adjustment capability allows the system to optimize its output characteristics and effectively control the projected light spot size, resolving the contradiction between high luminous flux and controlled volume.
2Productivity
If green and red laser diodes are used to enhance output light components, then the luminous flux output is improved, but the cost of the light source system increases significantly
Solution Approach 1:
The patent changes the spectral parameters of the light source by combining different types of light-emitting elements (LEDs and laser diodes) with complementary characteristics. This parameter optimization allows the system to achieve enhanced luminous flux output with cost-effective component selection, avoiding the need for expensive green and red laser diodes while maintaining performance.
3Area of moving object
If the moveable optical block is moved into the light path, then the light spot size is reduced, but the system complexity increases
Solution Approach 1:
The patent employs a moveable optical block that can be positioned at different locations along the light path to dynamically control the light spot size. This dynamic adjustment mechanism provides flexible control over the output characteristics without requiring complex optical systems, achieving simple yet effective light spot size reduction when needed.
