Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If equivalent electronic and mechanical components are used to build training and simulation systems, then the fidelity and realism of the training environment is improved, but the system complexity and cost increase
Solution Approach 1:
The patent creates a simplified copy of the control panel interface that replicates the visual and tactile experience of the actual system without requiring equivalent internal electronics. The capacitive touch surface mimics the appearance and feel of physical controls while using fundamentally different sensing technology underneath, allowing high-fidelity training appearance with reduced complexity
Solution Approach 2:
The patent replaces complex mechanical wiring and electronic connections with capacitive touch sensing technology. Instead of using actual electrical connections between components, the system uses capacitive fields to detect control inputs, substituting a simpler electromagnetic field-based system for complex mechanical and electrical assemblies
2Reliability
If fully wired training and simulation systems are used, then the operational accuracy is improved, but the mobility and reassembly capability deteriorate
Solution Approach 1:
The patent eliminates mechanical wiring harnesses and electrical connections by using capacitive touch sensing throughout the control panel. This wireless sensing approach allows the training system to be easily disassembled, transported, and reconfigured without dealing with complex wiring, while still accurately detecting control inputs through capacitive field changes
Solution Approach 2:
The capacitive touch control panel serves multiple functions: it provides visual display, tactile feedback, and input detection all through a single integrated surface. This multi-functionality replaces what would traditionally require separate wired components for display, sensing, and control, enabling mobility while maintaining operational accuracy
3Reliability
If equivalent electronic components are used in training systems, then the training realism is improved, but the assembly and disassembly time increases
Solution Approach 1:
The patent creates a visual and tactile copy of the actual control panel interface that maintains training realism without requiring equivalent internal electronics. The capacitive touch surface replicates the appearance, layout, and feedback characteristics of physical controls, providing realistic training experience with simplified internal construction that enables rapid assembly and disassembly
Solution Approach 2:
The patent replaces time-consuming mechanical assembly of wired electronic components with a integrated capacitive touch panel that functions as a complete unit. This substitution eliminates the need to connect numerous electrical harnesses and mechanical linkages during assembly, dramatically reducing setup time while maintaining training realism through accurate capacitive sensing
