Solution Overview

Problem

Existing guide devices for motor vehicle lifting platforms are complex to install and maintain, often requiring multiple people and climbing aids, with limited accessibility for maintenance and repair due to their elevated position.

Innovation Solution

A pivotable guide device with a joint mechanism that allows easy installation and maintenance, featuring a detachable connection system with reduced structural complexity, enabling single-person operation and secure locking in a working position, thus minimizing hindrance during platform use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed cable bridge is used between lifting columns, then the connecting lines are securely routed, but the installation and maintenance become complex and require multiple people and climbing aids

Engineering Contradiction:
Improvesecure routing of connecting linesVSAvoidinstallation and maintenance complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The guide device is divided into a first guide portion and a second guide portion that can be independently installed on different lifting columns. This segmentation allows each portion to be installed separately using simple mounting brackets, eliminating the need for complex assembly by multiple people while maintaining secure line routing between columns

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide device incorporates pivotable connections that allow the guide portions to rotate relative to each other and to the lifting columns. This dynamic capability enables the device to adapt to column movement and positioning adjustments, maintaining functional reliability while simplifying installation and maintenance operations

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the cable bridge is positioned high above the lifting area, then it does not impede work on the lifting platform, but accessibility for maintenance and repair is limited

Engineering Contradiction:
Improveminimal hindrance during platform useVSAvoidaccessibility for maintenance
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The guide portions are designed to pivot between a raised position (when not in use) and a lowered position (during maintenance). This dynamic positioning allows the device to clear the lifting area during operation while enabling easy access to connecting lines and components during maintenance without requiring climbing aids

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The vertical position parameter of the guide portions can be changed between elevated and lowered states. This parameter change allows the device to optimize its position based on operational requirements - high during lifting operations to avoid interference, and low during maintenance for accessibility

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If a rigid crossbar design is used, then the structure is stable, but the assembly requires several people and complex procedures

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly simplicity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The rigid crossbar is segmented into multiple independent guide portions that can be manufactured and assembled separately. Each portion maintains structural stability for its local function while the overall assembly becomes simpler and can be completed by a single person using individual mounting brackets

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple simple mounting brackets and guide portions are combined to create the complete guide device. This merging of simple components achieves the structural stability of a rigid crossbar while maintaining ease of assembly and manufacture

Inventive Principle:
Principle #5Merging (Combining)
