Long Member Holder Assembly for Twist-Resistant Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders for long members often interfere with each other when a twisting force is applied, leading to inadequate anti-vibration performance due to the lack of involvement of the anti-vibration member.
Innovation Solution
The holder includes a holding member, an anti-vibration member made of an elastic material, and a fixing member with an extension portion and pressing protrusions that prevent interference between the holding member and the fixing member, ensuring the anti-vibration member is effectively engaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the holder is assembled with the flange of the fixing member facing the upper end surface of the frame-shaped body portion, then the structure is simple and easy to assemble, but the holding member and fixing member interfere with each other when a twisting force is applied, compromising anti-vibration performance
Solution Approach 1:
The pressing protrusion extends in the radial direction (perpendicular to the insertion direction) of the insertion portion, creating a new dimensional relationship between the fixing member and frame-shaped portion. This radial extension allows the pressing protrusion to contact the frame-shaped portion from the side, preventing interference between the holding member and fixing member during twisting while maintaining simple assembly through the insertion mechanism
2Reliability
If the anti-vibration member is positioned between the holding member and fixing member, then anti-vibration performance is improved, but the members may still come into contact and interfere with each other under twisting forces
Solution Approach 1:
The pressing protrusion is designed to press against the frame-shaped portion in advance, creating a preliminary counteracting force that prevents the holding member and fixing member from interfering with each other during twisting operations. This pre-positioned pressing action maintains the structural stability of the assembly while allowing the anti-vibration member to function effectively

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively inhibits interference between the holding member and the fixing member, allowing the anti-vibration member to maintain sufficient anti-vibration performance even when a twisting force is applied.
Implementation Method 1
an anti-vibration member that is made of an elastic material and includes a frame-shaped portion configured to be inserted into the frame-shaped body portion
Implementation Method 2
a pressing protrusion that presses an inner surface of the frame-shaped portion when the frame-shaped portion is inserted into the frame-shaped body portion

AI summary
A holder for a long member includes: a holding member that includes a frame-shaped body portion; an anti-vibration member that is made of an elastic material and includes a frame-shaped portion; and a fixing member that is provided with an insertion portion. The insertion portion includes an extension portion extending in an insertion direction in which the insertion portion is inserted into the frame-shaped portion. A pressing protrusion protrudes on an outer surface of the extension portion, and when the frame-shaped portion is inserted into the frame-shaped body portion and the insertion portion is inserted into the frame-shaped portion, the pressing protrusion presses an inner surface of the frame-shaped portion and an outer surface of the frame-shaped portion comes into pressing contact with an inner surface of the frame-shaped body portion.
