Solution Overview

Problem

Conventional tube holders face difficulties in securely fixing tubes due to mismatched diameters, leading to friction issues during assembly and potential movement of tubes under vibrations, and require complex assembly processes with separate components that can be prone to damage.

Innovation Solution

A vehicular tube-holding device comprising an outer holder mounted to the vehicle body and an inner holder inserted into it, featuring a one-touch fastening mechanism with elastic hooks and a slide groove for easy assembly and secure tube fixation, allowing close contact with the tube to prevent movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional tube holder with a predetermined diameter tube-fixing hole is used, then the holder structure is simple, but the tube cannot be smoothly inserted when the tube diameter is greater than the hole diameter due to friction

Engineering Contradiction:
Improvetube insertion easeVSAvoidholder structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The holder body is divided into an upper holder and a lower holder that can be separated from each other. The tube-fixing hole is correspondingly divided into a first tube-fixing hole in the upper holder and a second tube-fixing hole in the lower holder. This segmentation allows the tube to be inserted through the divided holes without friction resistance from a continuous circular hole, while the holders can be coupled together to maintain structural integrity.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a separable configuration with upper and lower holders is used, then tube insertion is easier, but the holders need to be separately attached to the vehicle body causing deterioration in workability and productivity

Engineering Contradiction:
Improvetube assembly workabilityVSAvoidassembly productivity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The upper holder and lower holder are coupled together through a coupling structure where the coupling protrusion of one holder engages with the coupling recess of the other holder. This merging allows the divided holders to be assembled into a unified structure after tube insertion, maintaining structural integrity while preserving the ease of tube assembly achieved through segmentation.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the tube-fixing hole is divided into first and second holes, then tube insertion is facilitated, but the tube may not be firmly fixed unless the holes are accurately aligned to define a circle

Engineering Contradiction:
Improvetube insertion easeVSAvoidhole alignment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The coupling protrusion and coupling recess are pre-formed in the upper and lower holders respectively, with predetermined coupling positions. This preliminary action ensures that when the holders are coupled together, the first and second tube-fixing holes are automatically aligned to define a complete circular opening, eliminating the need for high-precision manual alignment during assembly.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If a hinge or clip structure is used to interconnect upper and lower holders, then the holders can be coupled, but the tube may separate when the hinge or clip structure is damaged

Engineering Contradiction:
Improvecoupling mechanismVSAvoidtube fixation reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The coupling protrusion and coupling recess form a robust, simple mechanical coupling that prioritizes reliability over complexity. This coupling structure is designed to be durable and resistant to damage, ensuring that the tube remains firmly fixed even under vibration and external forces, without relying on fragile hinges or clips.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
