Solution Overview

Problem

Existing methods for mounting cables on vehicle headliners are cumbersome, requiring skilled labor, prone to incorrect positioning, and can cause noise due to direct contact with the roof panel, especially when using adhesives or fusion methods.

Innovation Solution

The use of VELCRO tape with hook and loop fasteners for attaching cables to headliners, allowing easy attachment, adjustment, and separation of cables, even by unskilled workers, and preventing noise by acting as a noise pad without the need for additional noise pads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If cable is fixed to headliner through fusion or adhesive agent, then cable is securely fixed, but cable cannot be separated from headliner causing waste of headliner

Engineering Contradiction:

Improveadhesive forceVSAvoidseparability

Core Design Contradiction:

StrengthVSEase of repair

Solution Approach 1:

The attachment system is divided into two separable components: a VELCRO tape attached to the headliner and another VELCRO tape attached to the cable. This segmentation allows the cable to be securely fixed while maintaining the ability to separate and reattach, eliminating headliner waste.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The VELCRO fastening system allows for easy separation and recovery of the cable from the headliner. If positioning is incorrect or replacement is needed, the cable can be separated and reattached without damaging or wasting the headliner material.

Inventive Principle:

Principle #34Discarding and recovering

2Reliability

If cable is securely attached to headliner, then cable is fixed, but cable cannot be separated making headliner waste

Engineering Contradiction:

Improvefixing reliabilityVSAvoidheadliner waste

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

By dividing the attachment mechanism into two separate VELCRO components (one on headliner, one on cable), the system achieves reliable fixing while enabling separation, thus preventing headliner waste.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The VELCRO tape acts as an intermediary between the cable and headliner, providing secure attachment while allowing for clean separation without damaging either the cable or headliner.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If cable attaching position is incorrect, then assembly cannot proceed, but separating and reattaching cable is cumbersome

Engineering Contradiction:

Improvepositioning accuracyVSAvoidassembly efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The segmented VELCRO attachment system allows the cable to be easily separated and reattached if positioning is incorrect, enabling quick corrections without cumbersome procedures and maintaining assembly efficiency.

Inventive Principle:

Principle #1Segmentation

4Reliability

If simple works are repeated to fix cable after attachment, then cable is secured, but process becomes cumbersome

Engineering Contradiction:

Improvecable fixationVSAvoidprocess complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The VELCRO fastening function combines attachment and noise prevention into a single integrated solution. The VELCRO tape not only secures the cable to the headliner but also acts as a noise pad, eliminating the need for separate noise prevention components and simplifying the overall process.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The VELCRO tape serves multiple functions simultaneously: it provides secure cable attachment and acts as a noise-preventing pad. This multi-functionality reduces process complexity by eliminating the need for separate noise pad attachment steps.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method of mounting a cable on a headliner and a headliner used therefor, that are capable of simplifying an attachment process by attaching the cable to the headliner using an attaching cloth, and preventing the attached cable from being easily separated from the headliner and securely fixing the cable to reduce generation of noises. The method is capable of easily recognizing a cable mounting position and arbitrarily adjusting the cable mounting position to a width of an attaching cloth. A worker may easily perform an assembly process by attaching the cable using the attaching cloth, separating an incorrectly attached cable and then attaching the cable thereto again.The attaching cloth may be at a mounting position of a headliner opposite to a roof panel and at which a cable is mounted, and at an outer circumferential surface of the cable, respectively.
