Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If portable handheld X-ray equipment is used to enable inspection at any location, then convenience for examinees is improved, but the relative position and angle between X-ray emitter and sensor become unstable
Solution Approach 1:
The patent implements a feedback mechanism where the system automatically detects the relative position and angle between the handheld X-ray emitter and sensor, compares it with pre-stored reference data, and provides real-time guidance to the operator to adjust the positioning, ensuring stable and accurate alignment during portable inspection
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated optical detection system that uses light emission and reception to measure angles and positions, substituting the need for manual alignment mechanisms with an intelligent guidance system that automatically ensures proper positioning
2Ease of operation
If manual positioning of handheld X-ray emitter is used to simplify operation, then ease of operation is improved, but radiation safety is compromised due to incorrect positioning
Solution Approach 1:
The patent performs preliminary detection of the relative position and angle between emitter and sensor before radiation emission, comparing measured values with pre-stored reference data to verify correct positioning, and only allows radiation emission when positioning meets safety requirements
Solution Approach 2:
The system performs self-verification of positioning accuracy by automatically detecting and comparing positional parameters, and autonomously controls the radiation emission switch based on whether positioning requirements are met, eliminating the need for manual safety checks
3Object-affected harmful factors
If automated positioning detection is implemented to ensure safety, then radiation safety is improved, but device complexity increases
Solution Approach 1:
The patent makes the transceiver device serve multiple functions: it acts as both a communication device for data transmission and a positioning detection device by emitting light and receiving reflections, thereby achieving positioning detection without adding separate dedicated hardware components
Solution Approach 2:
The patent introduces light as an intermediary carrier to transmit positioning information between the emitter and sensor, using light emission and reception to indirectly measure relative position and angle, avoiding the need for direct complex mechanical measurement mechanisms
