Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical input devices are placed in distant locations to accommodate multiple displays and gauges, then the operator can monitor more instruments, but the operator experiences discomfort and safety risks due to reaching for distant controls
Solution Approach 1:
The patent replaces the mechanical interaction system (direct contact with switches and buttons) with an optical detection system (RADAR sensors that detect hand movements and gestures). This allows the operator to control distant devices without physical contact, resolving the contradiction by substituting the mechanical operation mode with a non-contact optical detection mode.
2Adaptability or versatility
If mechanical input devices are placed in distant locations, then more displays can be monitored, but the operator must reach for controls which creates safety risks
Solution Approach 1:
The system replaces mechanical actuation with optical gesture recognition. RADAR sensors detect hand movements and translate them into control signals, eliminating the need for operators to physically reach for distant controls and thereby maintaining safe operation while monitoring multiple instruments.
Solution Approach 2:
The patent introduces an intermediary system (RADAR sensors and gesture recognition algorithms) between the operator and the mechanical input devices. This intermediary translates hand gestures into control actions, allowing the operator to interact with distant devices without direct physical contact.
3Ease of operation
If operators directly contact mechanical input devices, then precise control is achieved, but the devices suffer from wear and tear due to continuous contact
Solution Approach 1:
The patent substitutes mechanical contact-based control with optical gesture-based control. RADAR sensors detect hand movements and finger gestures to generate control signals, eliminating physical contact between the operator and mechanical devices, thereby preventing wear and tear while maintaining control precision.
Solution Approach 2:
The system creates a virtual copy of the mechanical interaction through optical detection. Instead of directly actuating mechanical switches, the RADAR system detects and tracks hand movements, creating a digital representation of the intended control action that is then executed electronically.
4Ease of operation
If mechanical input devices are located within easy reach, then operator comfort is improved, but the layout cannot accommodate multiple displays and gauges
Solution Approach 1:
By replacing mechanical contact with optical gesture detection, the system decouples the physical distance between the operator and controls from the ability to operate them. This allows displays and gauges to be positioned optimally for monitoring while controls remain accessible through gesture recognition, resolving the layout conflict.
