Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are connected to functional units via cable connections inside the housing, then the electrical connection is stable, but the cable connections can jam or tear off during maintenance leading to high repair costs
Solution Approach 1:
The patent divides the housing into separable outer and inner housings that can be detached from each other. This segmentation allows the inner housing containing functional units to be removed independently for maintenance without disturbing the sensor connections in the outer housing, thus maintaining connection stability while enabling easy repair.
Solution Approach 2:
The patent extracts the functional units into a separate removable inner housing that can be taken out independently. This extraction allows maintenance personnel to access and service functional units without risking damage to the electrical connections of sensors that remain in the outer housing.
2Device complexity
If electrical contacts are fixed on the inner housing, then the connection structure is simple, but the electrical contacts cannot be adapted to different sensors
Solution Approach 1:
The patent makes the electrical connection system dynamic by providing multiple replaceable connector assemblies with different contact configurations. These connector assemblies can be exchanged depending on the sensor type being used, allowing the system to adapt to different sensors while maintaining a simple overall connection structure through standardized mounting interfaces.
Solution Approach 2:
The patent creates a universal connection system where the inner housing can accommodate multiple types of connector assemblies through a standardized interface. This allows the same inner housing structure to work with different sensors by simply changing the connector assembly, achieving multi-functionality without increasing overall device complexity.
