Solution Overview

Problem

Tracked lifting platforms face challenges in reducing visible mechanics below the track and achieving flexible adjustment in lifting height, which limits accessibility and adaptability to customer requirements.

Innovation Solution

The tracked lifting platform incorporates pressure-resistant push columns with multiple push members, arranged vertically and connected via a deflection axis, allowing for adjustable lifting height and reduced visible mechanics by forming a single vertical column in the working position, with each end region featuring at least one push column oriented in opposite directions for stability and support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional lifting mechanisms (scissors or parallelogram mechanics) are used, then the track can be lifted and lowered, but visible mechanics below the track increases and accessibility is reduced

Engineering Contradiction:
Improveaccessibility below trackVSAvoidvisible mechanics
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lifting mechanism is divided into multiple independent push members (first, second, third push members) that can be arranged vertically. Each push member operates independently to lift the track, eliminating the need for complex interconnected scissors or parallelogram mechanisms visible below the track.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The push members are arranged vertically (in the height dimension) rather than horizontally spreading out below the track. This vertical stacking conceals the mechanics from lateral view while maintaining lifting functionality, effectively moving the mechanism from a 2D plane to a 3D arrangement.

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

2Adaptability or versatility

If fixed lifting height is used, then the structure is simple, but adaptability to customer requirements regarding lifting height is reduced

Engineering Contradiction:
Improvelifting height adjustmentVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lifting mechanism transitions from a fixed configuration to a dynamic, adjustable configuration. The number of push members can be varied, and they can be arranged at different vertical positions, allowing the lifting height to be adapted to different customer requirements while maintaining a relatively simple basic structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lifting height parameter can be changed by adjusting the number of push members and their vertical arrangement. This allows continuous or discrete adjustment of the lifting height without fundamentally changing the basic mechanism design, providing versatility while keeping the structure simple.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If multiple push members are arranged vertically to form a single column, then visible mechanics is reduced and accessibility is improved, but the ability to support pressure loads is challenged

Engineering Contradiction:
Improvevisible mechanicsVSAvoidpressure resistance
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

Multiple push members are combined vertically to form a single integrated push column. The first, second, and third push members work together as a unified structure to support pressure loads, merging their individual load-bearing capacities into a collective strength that rivals or exceeds traditional horizontal arrangements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The push members utilize pneumatic or hydraulic actuation to generate the necessary pushing forces. This allows compact, high-force generation in a vertical arrangement, enabling the vertical column to support heavy loads despite the constrained geometry.

Inventive Principle:
Principle #29Pneumatics and hydraulics
