Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional display screens are used, then the device structure is simple, but the device lacks flexibility and has higher power consumption
Solution Approach 1:
The patent employs a flexible screen composed of multiple layers including flexible substrate, display layers, and sensor layers that can be bent without damage. This flexible structure enables the device to achieve various bending states while maintaining functionality, directly addressing the flexibility requirement without significantly increasing overall device complexity
2Measurement precision
If flexible screen is implemented, then the device achieves lighter and thinner size with reduced power consumption, but the method to calculate bending angle is lacking
Solution Approach 1:
The patent divides the flexible screen into multiple regions with accelerometers positioned at different locations (e.g., first accelerometer at first position, second accelerometer at second position). Each accelerometer independently detects local acceleration, and the processing module combines these segmented measurements to calculate the overall bending angle, achieving precise measurement while keeping individual sensor components simple
Solution Approach 2:
The patent replaces complex mechanical bending angle measurement mechanisms with acceleration sensor-based detection. By using accelerometers to detect gravitational acceleration components and applying mathematical calculations in the processing module, the system achieves accurate bending angle measurement without mechanical linkages or complex physical measurement structures
3Measurement precision
If accelerometers are positioned at different locations on the flexible screen, then the bending angle can be accurately detected, but the device complexity increases
Solution Approach 1:
The patent designs the processing module to perform multiple functions: it processes data from multiple accelerometers, calculates bending angles in various directions, determines bending states, and controls screen operations based on these measurements. This multi-functional approach allows accurate bending detection using a relatively simple processing unit, offsetting the complexity added by multiple sensors
