Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a curved cover window is attached to a display panel using conventional methods, then the display device can be manufactured, but the cover window may deform or misalign during the attachment process
Solution Approach 1:
The jig changes its structural parameters dynamically through rotation. When rotated to the first position, the supporting unit retracts to allow free placement of the curved cover window. When rotated to the second position, the supporting unit extends to provide support and fixation, thereby changing the physical state of the jig to match different process requirements and improve alignment precision without permanent complexity
Solution Approach 2:
The supporting unit is designed to be dynamically movable between retracted and extended positions via rotation of the jig. This dynamic capability allows the system to adapt during the attachment process: initially permitting easy placement of the cover window, then providing support and alignment as needed, resolving the contradiction between simplicity and precision
2Manufacturing precision
If the cover window is securely fixed during attachment, then manufacturing precision improves, but the ease of loading and unloading the cover window decreases
Solution Approach 1:
The supporting unit transitions from a retracted state during loading to an extended state during fixation. This dynamic behavior allows the cover window to be easily loaded when the supporting unit is retracted, then securely fixed when the jig rotates to the second position and the supporting unit extends, thus resolving the contradiction between ease of operation and fixation accuracy
Solution Approach 2:
The attachment process utilizes periodic rotation of the jig between two positions. During the first position, the supporting unit is retracted for easy loading. During the second position, the supporting unit extends for secure fixation. This periodic cycling between loading and fixation modes allows both ease of operation and manufacturing precision to be achieved at different stages of the process
3Productivity
If manual alignment methods are used for the curved cover window, then the device complexity remains low, but the manufacturing precision and throughput are insufficient
Solution Approach 1:
The curved support surface of the supporting unit is designed to automatically conform to the curved shape of the cover window. When the jig rotates to the second position, the supporting unit self-adjusts to the curvature of the cover window, providing automatic alignment without requiring complex external alignment mechanisms, thereby improving productivity while keeping device complexity manageable
Solution Approach 2:
The supporting unit incorporates a curved surface that matches the curvature of the cover window. This geometric correspondence allows the supporting unit to naturally guide and align the curved cover window during the attachment process, eliminating the need for complex alignment mechanisms while improving manufacturing precision and throughput
