Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a light source device uses a conventional configuration with multiple separate components for housing and sealing, then the device can provide adequate structural support and light transmission, but the configuration becomes complicated and the manufacturing process becomes cumbersome
Solution Approach 1:
The patent combines the housing body and sealing cover into a single integrated housing structure. The housing body includes a body portion and a cover portion that form a unified structure, eliminating the need for separate sealing components. This integration maintains structural integrity and light transmission while simplifying the overall device configuration and reducing manufacturing complexity.
Solution Approach 2:
The housing structure serves multiple functions simultaneously: it provides structural support, seals the light-emitting elements, and transmits light. The housing body is designed to perform both protective and optical functions, reducing the need for additional specialized components and simplifying the device architecture.
2Reliability
If a light source device uses a conventional configuration with multiple separate components, then the device can provide adequate functionality, but the manufacturing process becomes cumbersome and productivity decreases
Solution Approach 1:
By integrating the housing body and cover into a single component, the manufacturing process requires fewer assembly steps and fewer parts to be produced and handled. This reduces manufacturing complexity and improves production efficiency while maintaining all necessary functional capabilities of the device.
3Reliability
If a light source device uses a conventional configuration with multiple separate components, then the device can provide adequate performance, but the manufacturing costs increase due to complex processes
Solution Approach 1:
The integrated housing structure reduces the number of parts that need to be manufactured, stored, and assembled. This consolidation lowers material costs, reduces manufacturing overhead, and simplifies quality control processes, thereby reducing overall manufacturing costs while maintaining device performance.
4Strength
If the frame body is made of conductive material, then the structural strength is improved, but electrical interference with the light emitting elements may occur
Solution Approach 1:
The patent introduces an insulating layer as an intermediary between the conductive frame body and the light-emitting elements. This insulating layer prevents electrical interference and short circuits while allowing the frame body to maintain its structural strength and rigidity. The insulating layer acts as a mediator that enables the use of strong conductive materials without the harmful electrical effects.
