Solution Overview

Problem

Existing tire changers require a large footprint and have poor efficiency due to the tool bearing device hindering tire mounting and removal processes, and the need for frequent re-adjustment of tool positions.

Innovation Solution

A tire changer with a tool bearing device that moves vertically on a slider driven by a first driving device, utilizing a positioning mechanism to maintain tool position consistency, reducing the need for re-adjustment and minimizing space requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the tool bearing device is hinged with the supporting column to swing horizontally away from the wheel holder, then the hindrance to tire mounting/removal is eliminated, but the footprint of the tire changer increases

Engineering Contradiction:
Improvetire mounting and removal processVSAvoidfootprint of tire changer
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent changes the movement dimension of the tool bearing device from horizontal swinging to vertical sliding. The slider moves along the vertical direction of the supporting column, allowing the tool bearing device to move away from the wheel holder in the vertical dimension rather than requiring horizontal space. This resolves the contradiction by eliminating hindrance through vertical movement while maintaining a compact horizontal footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the supporting column and base adopt a hinged structure for rear inclination, then the tool bearing device can be moved away from the wheel holder, but the footprint of the tire changer increases

Engineering Contradiction:
Improvetool bearing device positioningVSAvoidfootprint of tire changer
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

Instead of using rear inclination of the supporting column (which requires rear space), the patent employs vertical sliding of the tool bearing device along the supporting column. This vertical movement achieves the same positioning function without requiring additional rear or side space, thus resolving the contradiction between operational ease and compact footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the tool bearing device is hinged with the supporting column, then the tool can be positioned away from the wheel holder, but the position of the disassembly tool changes after resetting, requiring re-adjustment

Engineering Contradiction:
Improvetool bearing device positioningVSAvoidtime for adjusting tool position
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the hinged mechanical connection with a sliding mechanism guided by the supporter. The slider moves along the vertical direction within the sliding cavity, providing stable and repeatable positioning. This mechanical substitution eliminates the position drift issue inherent in hinged structures, as the guided sliding path ensures the tool returns to the exact same position after each cycle, eliminating the need for re-adjustment and reducing time loss.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If the tool bearing device swings horizontally to avoid hindrance, then the tire mounting/removal process is facilitated, but the complexity of the device increases

Engineering Contradiction:
Improvetire mounting and removal processVSAvoidhinged structure with horizontal swing
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent simplifies the device by changing the movement from horizontal swinging (requiring hinges and swing mechanisms) to vertical sliding (requiring only a slider and guide). This dimensional change eliminates the complex hinged swing mechanism while achieving the same functional goal of moving the tool bearing device away from the wheel holder during tire operations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
