Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual wheel handling and water tank raising are used for airtightness detection, then the detection process can be completed, but labor intensity increases and water leakage occurs due to frequent tank movements
Solution Approach 1:
The patent replaces the manual mechanical system of raising and lowering the water tank with an automated inflation system. The wheel is inflated through an inflation hole after being positioned on the detection platform, eliminating the need to repeatedly raise and lower the water tank. This substitution of mechanical tank movement with automated inflation resolves the contradiction by maintaining detection reliability while improving automation.
Solution Approach 2:
The patent extracts the water tank from the frequent movement cycle by using a separate inflation mechanism. The inflation hole allows air to be introduced into the wheel without requiring the water tank to be raised, separating the inflation function from the tank positioning function. This extraction eliminates water leakage risks associated with frequent tank movements while maintaining automated operation.
2Productivity
If manual wheel carrying is used for airtightness detection, then the detection process can be completed, but labor intensity becomes particularly large and misjudgment occurs at fatigue
Solution Approach 1:
The patent implements a self-service detection system where the wheel is automatically positioned and inflated. The wheel rolls onto the detection platform automatically, and the inflation process occurs without manual intervention. This self-service mechanism eliminates manual carrying and the associated fatigue, maintaining high productivity while improving operational accuracy.
Solution Approach 2:
The patent introduces an intermediary inflation system that mediates between wheel positioning and airtightness detection. The inflation hole and inflation mechanism serve as intermediaries, allowing automatic inflation without manual handling. This intermediary system eliminates the need for workers to physically carry wheels, reducing labor intensity and preventing fatigue-related misjudgments while maintaining efficient detection.
3Productivity
If the water tank is frequently raised and lowered for detection, then multiple wheels can be detected, but water leakage becomes particularly prone
Solution Approach 1:
The patent replaces the mechanical system of raising and lowering the water tank with an automated inflation system using an inflation hole. The wheel is inflated through this hole after positioning, eliminating the need for frequent tank movements. This substitution maintains continuous detection capability while preventing water leakage associated with repeated mechanical tank operations.
Solution Approach 2:
The patent segments the detection process into separate functions: wheel positioning on the platform and inflation through the inflation hole. This segmentation allows the inflation function to be performed independently without moving the water tank, enabling continuous detection of multiple wheels while maintaining water tank stability and preventing leakage.
