Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple molds of different shapes and dimensions are prepared to produce high-pressure vessels of varying lengths, then the production flexibility and adaptability are improved, but the equipment investment and storage space requirements increase
Solution Approach 1:
The patent applies universality by designing a single mold that can produce liners of various lengths through adjustable positioning mechanisms. The mold includes a positioning member that can be moved along the mold to accommodate different liner length requirements, making one mold serve multiple functions that previously required separate dedicated molds for each size.
Solution Approach 2:
The patent implements dynamics by introducing a movable positioning member within the mold structure. This positioning member can be dynamically adjusted to different positions along the mold to define different liner lengths, transforming a static single-purpose mold into a dynamic multi-purpose tool that adapts to various production requirements.

The mold includes a positioning member that can be moved along the mold to accommodate different liner length requirements, making one mold serve multiple functions that previously required separate dedicated molds for each size.
Solution Approach 2:
The patent merges the functionality of multiple separate molds into a single integrated mold structure. By combining the capabilities of what would have been multiple dedicated molds into one adjustable mold, the invention consolidates storage requirements while maintaining the ability to produce various liner lengths.
3Weight of stationary object
If a single mold is used to produce liners of different lengths by adjusting the positioning member, then the equipment investment and storage space are reduced, but the device complexity increases
Solution Approach 1:
The patent implements dynamics by introducing a movable positioning member within the mold structure. This positioning member can be dynamically adjusted to different positions along the mold to define different liner lengths, transforming a static single-purpose mold into a dynamic multi-purpose tool that adapts to various production requirements.
Solution Approach 2:
The patent applies segmentation by dividing the mold into functional components, including a fixed mold body and a movable positioning member. This segmentation allows the positioning member to be independently adjusted without affecting the overall mold structure, simplifying the complexity management while maintaining versatility.

AI summary
A high-pressure vessel includes a liner and a reinforcing layer. The reinforcing layer includes an inner reinforcing layer and an outer reinforcing layer. Further, the inner reinforcing layer includes a first covering portion, a third covering portion, and a second covering portion. Edge surfaces of the first covering portion and the third covering portion that face each other are in contact with each other. Edge surfaces of the third covering portion and the second covering portion that face each other are also in contact with each other. The outer reinforcing layer covers the outside of the first covering portion, the third covering portion, and the second covering portion.
