Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pen is dropped onto a display module disposed on a stone surface plate to measure impact durability, then the evaluation process is simple and straightforward, but the evaluation results do not accurately reflect real-world usage conditions
Solution Approach 1:
The patent creates a virtual replica of the real-world environment where the display module is actually used. By constructing a three-dimensional model that includes the display module, housing, and surrounding structural elements, the system copies the spatial relationships and environmental conditions of actual usage. This virtual environment allows pen drop tests to produce results that accurately reflect real-world durability while maintaining operational simplicity through automated simulation.
Solution Approach 2:
The patent introduces a virtual environment as an intermediary between the simple pen drop test and the complex real-world usage conditions. This virtual model acts as a mediator that translates the simple impact test into an evaluation that accurately represents real-world scenarios, bridging the gap between ease of operation and reliability of results.
2Reliability
If the display module is evaluated under environmental conditions similar to actual usage, then the accuracy of durability assessment improves, but the complexity of the evaluation system increases
Solution Approach 1:
Instead of physically replicating complex real-world environments with multiple variables, the patent creates a virtual three-dimensional model that copies the essential spatial relationships and environmental conditions. This virtual replica includes the display module positioned within a housing structure, allowing accurate durability assessment without requiring physically complex evaluation equipment or setups.
Solution Approach 2:
The patent replaces complex physical evaluation systems with a virtual simulation system. Instead of building physically complex test rigs to replicate real-world usage conditions, the system uses computational modeling and virtual reality to create an accurate representation of the usage environment, thereby reducing physical complexity while maintaining or improving assessment accuracy.
3Ease of operation
If a simple stone surface plate is used for pen drop testing, then the evaluation setup is straightforward, but the results cannot simulate actual user scenarios such as folded display modules
Solution Approach 1:
The patent incorporates dynamic elements into the virtual model, allowing the display module to be positioned in various states including folded and unfolded configurations. The virtual environment can adapt to different usage scenarios by dynamically adjusting the position and orientation of the display module within the housing, enabling the same evaluation system to test multiple real-world conditions without changing the basic setup procedure.
Solution Approach 2:
The virtual evaluation system serves multiple functions by accommodating various usage scenarios within a single platform. The same three-dimensional virtual model can simulate pen drop tests for folded display modules, unfolded modules, and different housing configurations, making the evaluation system universally applicable to diverse real-world conditions while maintaining ease of operation.
