Non-metallic Bracket with Metallic Insert for Hydraulic Hose
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle hydraulic systems face challenges in securely attaching hydraulic hoses to non-metallic components without causing deformation or leakage, particularly due to the lack of effective force distribution and sealing mechanisms in non-metallic brackets.
Innovation Solution
A non-metallic bracket design featuring a tubular insert and support ring within the hydraulic hose attachment port, which includes a deformable seal and a conically shaped bushing contact surface, facilitates secure hose attachment by distributing force and preventing leakage through a metallic tubular insert and support ring, ensuring reliable and repeated connections without deforming the non-metallic body.

Engineering Contradiction Analysis
1Weight of moving object
If a non-metallic bracket is used for bicycle hydraulic components, then weight is reduced and corrosion resistance is improved, but the ability to securely attach hydraulic hoses without deformation or leakage is worsened
Solution Approach 1:
The bracket combines non-metallic material (for weight reduction and corrosion resistance) with a metallic force receiving member (for strength and force distribution). This composite structure allows the bracket to maintain the advantages of non-metallic materials while incorporating the load-bearing capabilities of metal to prevent deformation during hose attachment.
Solution Approach 2:
The metallic force receiving member acts as an intermediary between the hose fastening fitting and the non-metallic bracket body. It receives and distributes the attachment forces, preventing direct transmission of deformation forces to the non-metallic material, thereby ensuring reliable hose attachment without compromising the bracket's weight or corrosion resistance benefits.
2Ease of operation
If a hose fastening fitting is screwed into a non-metallic bracket, then hose attachment is achieved, but deformation of the non-metallic body and leakage occur due to insufficient force distribution
Solution Approach 1:
The force receiving member is strategically positioned within the bracket body at the specific location where the hose fastening fitting attaches. This localized reinforcement provides enhanced force distribution capabilities exactly where needed, while the rest of the non-metallic bracket body maintains its original properties. The local quality change ensures proper force distribution during attachment without requiring the entire bracket to be made of heavier or more complex materials.

AI summary
A non-metallic bracket for a bicycle hydraulic component is basically provided with a non-metallic body and a force receiving member. The non-metallic body has a hydraulic hose attachment port and an internal fluid passage. The hydraulic hose attachment port has an insertion opening disposed at an exterior surface of the non-metallic body and an internal attachment bore extending from the insertion opening towards the internal fluid passage. The internal attachment bore of the hydraulic hose attachment port includes an internal screw thread portion that threadedly receives a hose fastening fitting. The force receiving member is provided to the non-metallic body so as to receive force applied to the non-metallic body in an area of the hydraulic hose attachment port caused by screwing the hose fastening fitting into the internal screw thread portion of the non-metallic body.
