Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual operation surface is set in real space for controlling device operations, then the operation can be performed without direct contact with the device, but the ease of operation becomes difficult to achieve
Solution Approach 1:
The patent extends the operation interface from a traditional 2D touch screen to a 3D virtual operation surface in real space. The imaging unit detects the 3D positions of body parts, and the processor determines operations based on spatial relationships in three-dimensional space, allowing users to interact with the device without direct contact while maintaining ease of operation through natural body movements.
Solution Approach 2:
The patent introduces a virtual operation surface as an intermediary between the user's body parts and the device operations. This virtual surface, detected through imaging technology, mediates the interaction by translating physical body positions into device commands, enabling contactless operation while preserving intuitive control.
2Ease of operation
If hand movement is used to control device operations, then direct contact with the device is not required, but the operation becomes less intuitive and comfortable
Solution Approach 1:
The patent replaces traditional mechanical touch input mechanisms with an optical imaging system. The imaging unit captures visual data of body parts in real space, and the processor translates these visual measurements into operation commands, substituting physical contact-based mechanical interaction with optical detection and digital processing.
Solution Approach 2:
The patent changes the detection parameters from 2D touch coordinates to 3D spatial positions of body parts. By detecting position, distance, and spatial relationships in three-dimensional space, the system enables more intuitive and comfortable operation while accurately measuring body part movements without requiring direct contact with the device.
