Solution Overview

Problem

Conventional methods for disassembling inner supports in vehicle tires are complex, time-consuming, and require heavy hydraulic devices, making on-demand assembly and disassembly impractical outside of a factory setting.

Innovation Solution

A device comprising a supporter, fastening belt, retracting device, securing device, and gear unit, where the retracting device is connected to the gear unit, allowing for easy compression and removal of the inner support using a manual or electric mechanism, facilitating simple and fast assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a hydraulic device is used for disassembling the inner support, then the disassembling force is sufficient, but the device becomes heavy and complex

Engineering Contradiction:

Improvedisassembling forceVSAvoiddevice complexity

Core Design Contradiction:

ForceVSDevice complexity

Solution Approach 1:

The device is divided into multiple functional modules: a supporter for positioning the tire, a retracting device with gear unit for generating disassembling force, a fastening belt for securing the inner support, and a securing device with guide rods for maintaining structure. This segmentation allows each module to perform its specific function efficiently while keeping the overall device simple and manageable.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces the hydraulic mechanical system with a manual or electric retracting device connected to a gear unit. This substitution eliminates the need for heavy hydraulic equipment while still generating sufficient disassembling force through mechanical advantage provided by the gear mechanism and winch system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a hydraulic device is used for disassembling the inner support, then the disassembling capability is achieved, but the assembling and disassembling process becomes time-consuming

Engineering Contradiction:

Improvedisassembling capabilityVSAvoidassembling and disassembling time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The fastening belt is pre-configured with the retracting device and securing device before use. The guide rods are pre-positioned to guide the inner support during disassembly. This preliminary preparation allows the actual disassembling operation to proceed quickly without requiring complex setup or adjustment during the process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The retracting device with winch mechanism provides dynamic control over the fastening belt tension, allowing rapid adjustment during the disassembling process. The gear unit enables quick retraction and release of the belt, facilitating fast assembly and disassembly operations while maintaining reliable disassembling capability when needed.

Inventive Principle:

Principle #15Dynamics

3Force

If a hydraulic device is used for disassembling the inner support, then the disassembling force is adequate, but the device cannot be used for on-demand assembly and disassembly outside of factory

Engineering Contradiction:

Improvedisassembling forceVSAvoidon-demand assembly and disassembly capability

Core Design Contradiction:

ForceVSAdaptability or versatility

Solution Approach 1:

The device is designed with multi-functional capabilities: the supporter can position the tire in various orientations, the retracting device can both compress and release the inner support, and the fastening belt can be quickly attached and detached. This universality allows the device to be used for on-demand assembly and disassembly operations outside of factory settings, unlike specialized hydraulic equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device is designed to be self-contained and self-operable without requiring external hydraulic infrastructure. The manual or electric retracting device can be independently operated to generate the necessary disassembling force, making the system portable and adaptable for field use where hydraulic systems are unavailable.

Inventive Principle:

Principle #25Self-service
