Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If camera systems are used to check plug alignment, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex optical measurement systems (camera-based) with a simple pressure sensing mechanism. A pressure sensor detects pressure changes in the hollow body when a plug is inserted, providing a straightforward mechanical/electrical signal that indicates correct alignment without requiring complex image processing or optical components.
Solution Approach 2:
The invention uses pneumatic principles by introducing a medium (gas or liquid) into the hollow body and measuring pressure changes. The pressure sensor detects whether the plug correctly seals the opening, transforming the alignment verification problem into a simple pressure measurement task that avoids complex mechanical and optical systems.
2Device complexity
If fiber optic systems are used to detect plug presence, then device complexity is reduced, but measurement precision deteriorates (cannot ensure proper alignment)
Solution Approach 1:
The patent employs pneumatic pressure measurement to simultaneously achieve system simplicity and accurate alignment verification. By introducing a medium and measuring pressure changes, the system can detect both plug presence and correct alignment, overcoming the limitation of fiber optic systems that can only detect presence without verifying alignment.
Solution Approach 2:
The invention substitutes complex optical detection with a straightforward pressure sensing mechanism. The pressure sensor provides a clear, unambiguous signal about plug alignment status, achieving both simplicity and precision without the ambiguities of optical methods.
3Device complexity
If pressure sensing is used to detect plug alignment, then device complexity is reduced and cost is lowered, but measurement precision must be sufficient to distinguish aligned from misaligned plugs
Solution Approach 1:
The patent utilizes parameter changes in the pressure signal to distinguish between different plug states. By introducing a medium and measuring pressure changes during or after plug insertion, the system creates distinct pressure signatures for correctly aligned, misaligned, and missing plug conditions, enabling reliable detection with simple pressure sensors.
