Solution Overview

Problem

Existing retention clips for mounting cables, wires, tubes, or pipes to a vehicle frame are costly due to the need for multiple molding steps and assembly processes, particularly when incorporating vibration-absorbing materials.

Innovation Solution

A modular retention clip design featuring a clamping body with rotatable body portions and isolation members made of resilient material, integrated with a living hinge and latching mechanism, which can be efficiently manufactured using a two-shot molding process and easily assembled with various bracket configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If vibration absorbing material is mounted as a separate part in the body portion, then vibration damping is improved, but part count and manufacturing cost increase due to added assembly steps

Engineering Contradiction:
Improvevibration dampingVSAvoidpart count
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The vibration absorbing material is integrated directly into the body portion of the retention clip as a unitary structure, eliminating the need for separate vibration damping parts and their associated assembly steps. This merging of functions reduces part count while maintaining vibration damping performance.

Inventive Principle:
Principle #5Merging (Combining)

2Object-affected harmful factors

If vibration absorbing material is injection molded in a two-shot process, then vibration damping is improved, but manufacturing cost increases due to multiple molding steps for different bracket configurations

Engineering Contradiction:
Improvevibration dampingVSAvoidmanufacturing cost
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The retention clip is divided into two functional segments: a bracket portion that can be manufactured separately in various configurations, and a body portion with integrated vibration absorbing material. This segmentation allows the vibration damping feature to be incorporated once in the body portion design, while the bracket portion can be varied without requiring additional molding steps for each configuration.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple molding steps are used to manufacture retention clips with integral brackets of various configurations, then adaptability to different bracket configurations is improved, but manufacturing time and cost increase

Engineering Contradiction:
Improvebracket configuration versatilityVSAvoidmanufacturing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The body portion of the retention clip is designed as a universal component with integrated vibration absorbing material that can interface with multiple different bracket configurations. This universal design allows a single body portion design to serve multiple applications, eliminating the need for separate molding steps for each bracket configuration while maintaining adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A modular retention clip for retaining elongated articles to a structure includes a clamping body (10) having first and second body portions (16, 18) of a first rigid material positionable between an open position and an engaged position. Isolation portions (12) of a second resilient material are attached to the first and second body portions that contact and retain the elongated articles in the engaged position. A living hinge (30) integrally connects the first and the second body portions and a latching member (36) is arranged to be captured within a receiving cavity (38) retaining the first and second body portions together. At least one mounting pin (50, 52) extends from the second body portion. A bracket (60) having a receiving portion (62) and a mounting portion (64) has at least one hole (61, 68) in the receiving portion that accepts the mounting pin to fix the clamping body to the bracket. The bracket mounting portion attaches the bracket to the structure.
