Reinforcement Ring with Interlinked Core for Packer Pressure Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art reinforcement rings used in packer elements deform under high pressures, compromising their ability to maintain a circular cross-section and functionality.
Innovation Solution
A reinforcement ring design featuring an annular coil spring with a core unit formed by interlinked elements, which prevents deformation by maintaining structural integrity through a chain of male and female parts that engage to resist twisting and compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an annular coil spring is used as a reinforcement ring, then it provides flexibility and basic structural support, but it deforms and loses its circular cross-section under high pressure
Solution Approach 1:
The core unit is segmented into multiple discrete elements (at least three elements) that are interconnected through male and female engagement parts. This segmentation allows each element to independently resist deformation while collectively maintaining the circular cross-section under high pressure, preventing the spring from collapsing or distorting.
Solution Approach 2:
The reinforcement ring combines two different structural components: an annular coil spring (flexible, elastic) and a core unit with interlinked elements (rigid, geometrically constrained). This composite structure leverages the flexibility of the spring while the geometrically constrained core unit provides resistance to high pressure and maintains the circular cross-section, resolving the contradiction between flexibility and pressure resistance.
2Reliability
If the reinforcement ring is designed to withstand high pressure, then it maintains structural integrity, but the design complexity increases
Solution Approach 1:
The core unit is divided into multiple identical or similar elements (at least three) that can be manufactured using the same process and then assembled by interlocking their male and female parts. This modular segmentation maintains reliability under high pressure while controlling complexity through standardization and modularity.
Solution Approach 2:
Multiple functional requirements are merged into a single core unit structure: maintaining circular cross-section, resisting high pressure, and providing geometric constraint. By combining these functions into one integrated component that works with the spring, the design achieves high reliability without proportionally increasing overall complexity.

AI summary
A reinforcement ring, includes an annular coil spring with a core unit arranged inside to prevent deforming or twisting of the ring under load. The core unit is formed from a chain of interlinked elements, each having a male part and a female part; the male parts of each element being engaged with corresponding female parts of an adjoining element.
