Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an explosion-proof flowmeter is used in the paint system, then the safety in the explosion-proof area is improved, but the system cost increases and maintenance becomes difficult
Solution Approach 1:
The patent divides the flowmeter into two separate parts: an explosion-proof area flowmeter (placed in the non-explosion-proof area) and a non-explosion-proof area flowmeter (placed in the explosion-proof area). This segmentation allows each part to be optimized for its specific environment, reducing overall system cost while maintaining safety
Solution Approach 2:
The patent introduces a non-contact flowmeter as an intermediary device that measures paint flow rate without direct contact with the paint. This non-contact measurement capability allows the flowmeter to be placed in the non-explosion-proof area, eliminating the need for expensive explosion-proof certification while maintaining accurate measurement
2Reliability
If an explosion-proof flowmeter is disposed in the explosion-proof area, then the safety requirement is satisfied, but the maintenance becomes difficult
Solution Approach 1:
The patent extracts the flowmeter from the explosion-proof area and places it in the non-explosion-proof area. This extraction eliminates the maintenance difficulties associated with explosion-proof equipment while maintaining the ability to monitor paint flow rate, as the non-contact flowmeter can measure through the channel wall
3Ease of manufacture
If a noncontact flowmeter is disposed in the non-explosion-proof area, then the system cost is reduced and maintenance is simplified, but the safety in monitoring paint flow must be maintained
Solution Approach 1:
The patent replaces traditional contact-based flow measurement mechanisms with a non-contact flowmeter that uses electromagnetic or optical fields to measure paint flow rate. This substitution eliminates the need for the flowmeter to be explosion-proof while maintaining accurate measurement capability
