Cushion Insert With Slot And Spacer For Tubing Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cushion inserts for clamp assemblies are difficult to replace without altering the spatial relationship between the tubing and the support structure, as they become fixed and cannot be easily removed or replaced due to their configuration.
Innovation Solution
A cushion insert design featuring a body with a slot, first and second cushion halves that can be expanded to fit over a cylindrical member, a spacer to prevent excessive tightening, and a tab for alignment, allowing for easy installation and secure fastening within a clamp assembly, enabling replacement without changing the spatial relationship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a traditional cushion insert is used in a clamp assembly, then the tubing is securely held in place, but the cushion cannot be easily replaced without removing the clamp halves and altering the spatial relationship of the tubing to the support structure
Solution Approach 1:
The cushion insert is divided into a body portion and a separate replaceable cushion element. The cushion element can be independently removed and replaced without disturbing the clamp assembly structure or the spatial relationship of the tubing to the support structure. The body retains features like the slot, spacer, and tab while allowing cushion replacement.
Solution Approach 2:
The cushion element is nested within the body of the cushion insert, which itself is nested within the clamp assembly. This nested structure allows the cushion to be replaced by simply removing it from the body, while the body remains in place maintaining the spatial relationship. The cushion fits within the passageway defined by the body halves.
2Ease of repair
If the cushion insert is designed to be easily replaceable, then maintenance becomes simpler, but the structural integrity and secure fastening may be compromised
Solution Approach 1:
The body is pre-formed with a slot, spacer, and tab features that ensure proper positioning and secure fastening when the cushion element is installed. The slot allows the cushion halves to be expanded for installation while the spacer and tab are already in position to prevent excessive tightening and ensure correct alignment, respectively.
Solution Approach 2:
Different portions of the cushion insert have specialized functions: the body provides structural support with integrated positioning features (slot, spacer, tab), while the cushion element provides the compressible securing function. This local differentiation allows the cushion to be replaceable while the body maintains structural integrity and secure fastening capabilities.
3Ease of manufacture
If the cushion insert uses a simple single-piece design, then manufacturing is easier, but replacement requires cutting or extracting the cushion from the fixed tubing and support structure
Solution Approach 1:
The cushion insert is segmented into a body and a separate cushion element, both of which can be manufactured using standard injection molding processes. The body is manufactured with integrated slot, spacer, and tab features, while the cushion element is manufactured as a separate piece that fits within the body's passageway. This segmentation makes both manufacturing and replacement easier compared to a single-piece design.
Solution Approach 2:
The cushion element is designed to be dynamically replaceable while the body remains static. The body provides a stable structure with fixed spatial features, while the cushion element can be independently installed and removed. This dynamic design allows the cushion to be replaced without manufacturing complexity or extraction difficulty.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient replacement of worn-out cushion inserts by allowing the new insert to be easily placed and secured around the cylindrical member, preventing axial and rotational movement, while preventing excessive tightening that could damage the components.
Implementation Method 1
A first cushion half and a second cushion half of a new cushion are expanded to allow the new cushion to be placed on the cylindrical member and the first and second halves of the new cushion are allowed to retract and wrap around the cylindrical member

AI summary
A cushion insert includes a body having a slot. A first cushion half and a second cushion half extend in an arc in opposite directions from the slot and have ends spaced apart to form a gap in a location opposite the slot. A passageway extends axially through the cushion insert and is defined by the first cushion half and the second cushion half. A spacer extends axially along a top of the body and has a passage. A tab extends axially along a bottom of the body.
