Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If insertion-type light emitting elements with pin structures are used and bent during manufacturing to achieve certain orientation, then the light emitting direction can be controlled, but the manufacturing process becomes time-consuming and complicated
Solution Approach 1:
The patent extracts the light emitting elements from the traditional pin-structure insertion method and integrates them directly onto the circuit board using surface mount technology. This eliminates the need for separate bending and orientation adjustment steps, thereby improving manufacturing efficiency while maintaining precise control over light emitting directions through the planned arrangement of multiple LEDs
Solution Approach 2:
The patent combines the functions of mounting and orientation control into a single surface mount process. By integrating the light emitting elements directly onto the circuit board in predetermined positions and orientations, the manufacturing process merges what were previously separate steps (mounting + bending + alignment) into one efficient operation
2Manufacturing precision
If the pin structure is bent and fixed by soldering to orient light emitting elements, then alignment to certain direction is achieved, but defective products may be produced due to mistakable bending
Solution Approach 1:
The patent removes the bending step entirely from the manufacturing process by using surface mount technology. This extraction of the problematic bending operation eliminates the source of human error and defective products, while the predetermined placement positions on the circuit board ensure precise alignment is achieved through the design layout rather than manual bending
Solution Approach 2:
The circuit board design incorporates predetermined placement positions and orientations for the light emitting elements, allowing the assembly process to self-align components without manual bending. The board's structure itself provides the alignment references, making the system self-servicing and eliminating reliance on operator skill for precise orientation
3Illumination intensity
If insertion-type light emitting elements are used, then auxiliary illumination can be provided, but non-uniform illumination occurs with poor illumination at distant regions
Solution Approach 1:
The patent divides the illumination function into multiple independent light emitting elements arranged at different positions around the lens. By segmenting the illumination source into several LEDs with controlled directions, the system can provide focused illumination to specific regions while maintaining overall uniformity across the imaging area
Solution Approach 2:
The patent assigns different orientations and emission characteristics to individual light emitting elements based on their specific positions. Each LED is configured to illuminate its local region optimally, with the collective arrangement ensuring uniform overall illumination. This local optimization approach prevents the non-uniform illumination problems associated with single-point sources
4Manufacturing precision
If bending step is performed to every light emitting element for orientation alignment, then light direction control is achieved, but labor and time cost greatly increase
Solution Approach 1:
The patent extracts and eliminates the time-consuming bending step from the manufacturing process by adopting surface mount technology. Orientation control is achieved through the predetermined placement design on the circuit board rather than post-mounting bending operations, dramatically reducing manufacturing time
Solution Approach 2:
The circuit board is designed with predetermined placement positions and orientations for light emitting elements before the actual assembly takes place. This preliminary planning of component locations and angles eliminates the need for time-consuming adjustment and bending operations during manufacturing, as all orientation requirements are built into the board layout from the start
