Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the exposure device is tightly fixed to the housing with screws, then the optical settings remain stable and vibrations are prevented, but the maintenance work becomes inefficient and complicated
Solution Approach 1:
The exposure device is separated from the housing by introducing a support structure as an intermediate component. The exposure device is mounted on the support structure, which can be inserted into or removed from the housing, thereby segmenting the fixed connection into a modular assembly that maintains stability during operation but allows easy removal for maintenance.
Solution Approach 2:
The exposure device is extracted from the permanent fixed state by providing a removable support structure. The support structure can be pulled out of the housing through an insertion opening, allowing the exposure device to be easily removed for maintenance without requiring unscrewing or complex disassembly operations.
2Manufacturing precision
If the exposure device is tightly fixed to the housing, then vibrations and external forces cannot change the optical settings, but the worker must remove and precisely reposition the exposure device for maintenance
Solution Approach 1:
By segmenting the connection between the exposure device and housing through a removable support structure, the system allows the exposure device to maintain precise positioning during operation while enabling quick removal for maintenance without requiring time-consuming precise repositioning operations.
Solution Approach 2:
The support structure is pre-designed with insertion and positioning features that guide the exposure device into its correct position during reinstallation. This preliminary design of the support structure eliminates the need for time-consuming precise alignment operations during maintenance reinstallation.
3Stability of the object's composition
If the exposure device is firmly fixed with screws, then the optical settings are protected from changes, but the maintenance process becomes complex and time-consuming
Solution Approach 1:
The optical system stability is maintained by keeping the exposure device firmly mounted on the support structure, while the support structure itself is designed as a removable unit. This segmentation allows the optical system to remain stable during operation while simplifying maintenance to a simple plug-and-play replacement operation.
Solution Approach 2:
The complexity of maintenance is reduced by extracting the exposure device from the housing through a removable support structure. This allows maintenance workers to simply remove and replace the support structure without dealing with screws, clips, or complex fastening mechanisms, thereby reducing maintenance process complexity.
