Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If curved edges are provided in the flat blank for gripping beaded edges, then the holding stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies curvature to the retaining edges by forming them along arc-shaped cutting lines that follow the curvature of the container beaded edges. This allows the flat blank to conform to the cylindrical shape of containers when folded, improving grip stability without requiring complex pre-curved components.
Solution Approach 2:
The blank is divided into multiple straight cutting line segments that approximate a curved path. These segmented straight lines are easier to manufacture with standard cutting tools while still forming the necessary curved retaining edges when the blank is folded into its three-dimensional configuration.
2Ease of manufacture
If straight main cutting lines are used for retaining edges, then the manufacturing process is simplified, but the holding stability may be reduced
Solution Approach 1:
The straight cutting lines in the two-dimensional flat blank transform into curved retaining edges in the three-dimensional folded structure. This dimensional transformation allows simple straight cuts to produce the complex curved geometry needed for stable container engagement.
Solution Approach 2:
The arc-shaped arrangement of straight cutting line segments creates curved retaining edges when folded, maintaining holding stability through geometric configuration rather than requiring curved cutting paths.
3Stability of the object's composition
If tabs for connecting contact sections are added, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The tabs are integrated directly into the contact sections as integral parts of the same piece of material, eliminating the need for separate connecting components. This merging approach provides structural stability while minimizing the number of distinct elements.
Solution Approach 2:
The tabs are designed to self-align and self-connect with corresponding features on adjacent contact sections, providing automatic structural stabilization without requiring additional fastening mechanisms or complex assembly procedures.
