Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive probe testing systems are used to test film structure puncture resistance, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses a simplified mold copy that replicates the essential geometry of the product package interior. The mold includes slots and inserts that copy the critical features (corners, edges, protrusions) where puncture risks occur, allowing puncture testing without requiring the actual complex product or expensive probe systems.
Solution Approach 2:
The testing tool uses inexpensive, simple molds that can be easily manufactured and replaced. These molds serve as single-use or limited-use testing fixtures that eliminate the need for costly, maintenance-intensive probe testing systems while providing sufficient measurement capability for quality control.
2Reliability
If expensive probe testing systems with maintenance fees are used, then reliability of testing is improved, but loss of energy and operational cost increase
Solution Approach 1:
The mold-based testing tool is self-contained and requires no external power source, calibration systems, or maintenance infrastructure. The simple mechanical design allows operators to perform puncture tests independently without relying on expensive probe systems that require scheduled maintenance, calibration services, and technical support.
3Ease of manufacture
If simple testing methods are used to reduce cost, then ease of manufacture is improved, but measurement precision deteriorates
Solution Approach 1:
The mold is designed with specific local features including slots positioned at critical locations and inserts that replicate product geometry. These localized details concentrate the testing focus on areas most susceptible to puncture, providing precise measurement of puncture resistance at critical points without requiring complex overall system design.
Solution Approach 2:
The mold and insert assembly is pre-configured with the exact geometry and positioning needed for accurate puncture testing. By preparing the testing fixture in advance with precise slot locations and insert orientations, the system ensures consistent, repeatable measurements without requiring complex real-time adjustments or calibration during testing.
