Gas Shock Compression Apparatus with Nested Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The removal and installation of gas shocks can be hazardous due to the substantial force involved, as conventional wire binding methods can fail, leading to explosive decompression.
Innovation Solution
A compression apparatus with upper and lower nest arms and a rigid rod, featuring adjustable mounting features and a driver mechanism, securely constrains gas shocks to control compression and decompression, reducing the risk of sudden force release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wire binding is used to compress gas shocks, then the compression process is simple, but the reliability is poor due to wire breakage or slippage causing explosive decompression
Solution Approach 1:
The compression apparatus divides the compressible body into two ends, each engaged by separate nest arms (upper and lower). The mounting features are segmented into multiple openings that collectively collar each end, distributing the constraining force and preventing single-point failure that occurs with wire binding.
Solution Approach 2:
The nest arms are designed to nest around the ends of the compressible body, with mounting features that fit into and constrain the body ends. The lower nest arm traverses along the rigid rod within the structure, creating a nested configuration that securely holds the compressible body during compression and decompression.
2Device complexity
If conventional wire binding is used, then the device complexity is low, but the operator safety is compromised due to explosive force release
Solution Approach 1:
The rigid rod with thrust bearing and bushing provides a controlled compression path before actual compression occurs. The nest arms are pre-positioned to engage the compressible body ends, and the driver mechanism gradually applies force through the rod, cushioning the decompression process and preventing explosive release that endangers operators.
Solution Approach 2:
The rigid rod acts as an intermediary between the lower nest arm driver mechanism and the compressible body. The thrust bearing and bushing serve as intermediary elements that guide and control the lower nest arm's movement along the rod, mediating the force transmission and ensuring controlled compression and decompression rather than sudden force release.
3Reliability
If nest arms with driver mechanism are used, then the reliability improves, but the device complexity increases
Solution Approach 1:
The rigid rod serves multiple functions: it provides structural support, guides the lower nest arm movement, transmits compressive force, and works with the thrust bearing and bushing to enable controlled traversal. The nest arms simultaneously engage and constrain the compressible body while the driver mechanism operates, consolidating multiple functions into integrated components rather than separate systems.

AI summary
An apparatus for compressing or decompressing a compressible body is provided. The apparatus comprises an upper nest arm and a lower nest arm separated by a rigid rod. The upper nest arm has an upper nest arm mounting feature configured to receive a first end of the compressible body. The upper nest arm mounding feature is shaped to fit the contours of the compressible body. The lower nest arm has a lower nest arm mounting feature configured to receive a second end of the compressible body. The lower nest arm can traverse the rigid rod to either compress or decompress the compressible body.
