Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional physical operating elements and two-dimensional displays are used, then the device structure remains simple, but the user interaction complexity increases and information presentation is not optimized for human perception
Solution Approach 1:
The patent replaces physical operating elements (mechanical buttons, switches) with gesture recognition and voice command detection. The detection unit captures gestures in a detection region and converts them into control commands, eliminating the need for physical contact with operating elements. This substitution reduces mechanical complexity while improving ease of operation through more intuitive gesture-based interaction.
Solution Approach 2:
The patent transitions from two-dimensional displays to three-dimensional spatial presentation of operating elements and information. Virtual operating elements are projected into a three-dimensional detection region, allowing users to interact with controls in spatial space rather than on a flat surface. This dimensional enhancement optimizes information presentation for human perception and simplifies complex interactions.
2Loss of information
If more information is presented simultaneously to optimize human perception, then the information utility improves, but the interface complexity and operational difficulty increase
Solution Approach 1:
The patent segments information and operating elements into multiple virtual layers or zones within the three-dimensional detection region. Different types of information can be presented at different spatial locations or depths, allowing users to access relevant information without being overwhelmed by all data simultaneously. This segmentation maintains high information utility while reducing operational complexity through spatial organization.
3Ease of manufacture
If physical operating elements are used, then device manufacturing is simpler, but contactless control and hygiene are compromised
Solution Approach 1:
The patent replaces physical operating elements that require contact with gesture-based and voice-based control systems. The detection unit detects gestures in the air space without requiring physical contact, and voice commands are processed through acoustic sensors. This eliminates contamination risks associated with physical buttons and switches while maintaining manufacturing feasibility through software-based control recognition.
