Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional control devices with visual key structures are assembled using standard manufacturing processes, then production efficiency is maintained, but display position accuracy of functional icons deteriorates due to component and assembly tolerances
Solution Approach 1:
The patent applies preliminary action by performing position calibration before final assembly completion. The calibration process captures the actual positions of transparent keys relative to the display panel and pre-calculates offset values that will be used during operation, thereby achieving high precision without requiring extremely tight manufacturing tolerances
Solution Approach 2:
The patent changes the parameter of icon display coordinates based on measured positional offsets. By dynamically adjusting the display coordinates according to actual key positions captured during calibration, the system compensates for manufacturing variations and achieves accurate alignment between functional icons and transparent keys
2Manufacturing precision
If strict quality control is implemented to ensure accurate icon display positions, then manufacturing precision is improved, but production complexity and cost increase
Solution Approach 1:
The system performs self-calibration by automatically capturing key positions, calculating offsets, and storing calibration data without requiring manual measurement or complex external quality control equipment. The control device uses its own imaging device and processing capabilities to achieve precise alignment
Solution Approach 2:
The patent implements feedback by using the imaging device to capture actual key positions, comparing them with reference positions, and using the calculated offsets to adjust icon display locations. This closed-loop approach ensures continuous accuracy without complex external quality control mechanisms

AI summary
A method for calibrating a functional icon display position of a control device is provided. The control device includes a transparent key and a display panel. The method includes the following steps. Firstly, an image capturing device is used to photograph a functional icon, and thus a real spatial relationship of the functional icon in a visible region of the transparent key is obtained. Then, a position offset amount is obtained according to a result of comparing the real spatial relationship with a reference spatial relationship. If the position offset amount is larger than the enable calibration threshold value, a calibrated icon display start coordinate position is obtained according to the position offset amount. The present invention also provides a control device using the calibrating method.
