Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If individual radiators are arranged in rows for substrate irradiation, then irradiation coverage is improved, but repair complexity increases due to difficulty in identifying and realigning defective radiators
Solution Approach 1:
The irradiation system is divided into modular radiator units that can be independently removed and replaced. Each radiator module is designed as a separate interchangeable component, allowing defective radiators to be quickly identified and swapped without affecting other radiators in the array.
Solution Approach 2:
The radiator modules incorporate self-aligning features with guide rails and positioning elements that automatically ensure correct alignment when modules are reinstalled. This self-service mechanism eliminates the need for manual realignment and adjustment after repair, reducing both time and potential for errors.
2Manufacturing precision
If radiators are arranged in a fixed configuration for consistent irradiation, then irradiation uniformity is improved, but adaptability to different substrates decreases
Solution Approach 1:
The radiator module positions are designed to be dynamically adjustable along the irradiation path. Modules can be moved to different positions or configured in various patterns depending on substrate requirements, while maintaining precise positioning capabilities to ensure irradiation uniformity for each specific configuration.
Solution Approach 2:
The same radiator module design serves multiple functions and can be applied to different substrate types and sizes. The modular architecture allows the system to adapt to various substrate configurations while maintaining consistent irradiation quality through standardized module positioning and alignment mechanisms.
3Loss of time
If rapid module replacement is enabled for quick repair, then repair time is reduced, but risk of misalignment increases
Solution Approach 1:
Radiator modules are pre-equipped with alignment features, guide elements, and positioning mechanisms during manufacturing. These preliminary preparations ensure that when modules are quickly replaced during repair, they automatically align correctly without requiring time-consuming manual adjustment, thus preventing misalignment despite rapid replacement.
