Resin-Metal Vehicle Pipe Holder with Interposed Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle pipe holders are not optimized for size reduction, which is increasingly demanded due to the need for smaller devices and components in vehicles, while maintaining the ability to stably hold multiple pipes without significant dimensional errors or weight issues.
Innovation Solution
A vehicle pipe holder design featuring a resin-made holding member with separate metal mounting brackets that interpose between holding portions, allowing for compact size and enhanced stability by distributing the load and reinforcing the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the pipe holder size is reduced, then the device becomes more compact and space-efficient, but the structural strength and stability may be compromised
Solution Approach 1:
The pipe holder combines resin and metal materials to create a composite structure. The resin holding member provides the basic holding function and can be made compact, while the metal mounting bracket reinforces the structure at critical mounting points, ensuring sufficient strength despite the reduced overall size.
Solution Approach 2:
The pipe holder is divided into separate functional components: a resin holding member for gripping the pipes and a separate metal mounting bracket for structural support and vehicle mounting. This segmentation allows each component to be optimized independently - the holding member can be small and compact while the mounting bracket provides concentrated structural reinforcement where needed.
2Device complexity
If a single integrated holding member is used, then the structure is simpler, but the load-bearing capacity and stability are insufficient
Solution Approach 1:
The holding function and mounting function are separated into distinct components - the resin holding member with its holding portions for pipes, and the separate metal mounting bracket for vehicle mounting. This functional segmentation allows each part to be specialized and optimized for its specific purpose while working together as a system.
Solution Approach 2:
The holding connection portion acts as an intermediary element that couples the resin holding member to the metal mounting bracket. This connection structure enables the two different materials and functional zones to work together, transferring loads between the holding portions and the mounting bracket while maintaining the benefits of both materials.
3Device complexity
If the mounting bracket is integrated with the holding member, then the number of parts is reduced, but the ability to distribute load and reduce dimensional error is compromised
Solution Approach 1:
The holding member and mounting bracket are manufactured as separate components with distinct functional requirements. The resin holding member can be molded with high precision for the holding portions, while the metal mounting bracket can be separately fabricated with precise mounting features. This separation allows each component to be manufactured and quality-checked independently, reducing cumulative dimensional errors.
4Strength
If metal material is used throughout, then the strength and rigidity are high, but the weight increases
Solution Approach 1:
Metal material is used locally only in the mounting bracket where high strength and rigidity are required for vehicle mounting and load-bearing. The holding member that contacts the pipes is made of lighter resin material, reducing overall weight while maintaining sufficient strength at the critical mounting locations.
Solution Approach 2:
The pipe holder uses a composite construction combining resin and metal materials in appropriate locations. The resin providing lightweight holding functionality and the metal providing localized structural reinforcement, achieving an optimal balance between weight and strength.

AI summary
A vehicle pipe holder configured to hold two or more pipes in a vehicle, the vehicle pipe holder includes: a holding member that is made of resin and that includes a first holding portion configured to hold one of the pipes, a second holding portion configured to hold another one of the pipes, and a holding connection portion that couples the first holding portion and the second holding portion; and a mounting bracket that is made of metal, that is separate from the holding member, and that includes a vehicle mounting portion configured to be mounted to a vehicle and an insertion opening configured to be inserted with the holding connection portion. The mounting bracket is configured to be disposed between the first holding portion and the second holding portion upon assembly of the holding member and the mounting bracket.
