Solution Overview

Problem

Existing lifting tables deform under horizontal stresses due to load-bearing limitations, particularly affecting the frame's supporting components, which are not adequately reinforced by the size of the vertical springs.

Innovation Solution

A lifting table design featuring parallel stringers with transverse beams and circular beam portions around vertical springs, along with a scissor system, enhances structural rigidity and allows for automatic leveling, accommodating larger loads ergonomically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the vertical spring size is increased to reinforce the supporting components, then the load-bearing capacity improves, but the bulk of the lifting table increases and stacking becomes more difficult

Engineering Contradiction:
Improveload-bearing capacityVSAvoidbulk of the lifting table
Core Design Contradiction:
StrengthVSVolume of moving object

Solution Approach 1:

The patent introduces a circular part extending horizontally around the vertical spring, adding a dimensional element that provides reinforcement without increasing the vertical height. This horizontal reinforcement dimension allows the structure to bear larger loads while maintaining a compact vertical profile suitable for stacking.

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

Solution Approach 2:

The supporting component combines the vertical spring element with the horizontal circular beam portion to create a composite structural system. This composite design integrates two different structural elements (vertical spring and horizontal circular reinforcement) that work together to provide enhanced load-bearing capacity without proportionally increasing overall volume.

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If the supporting components are reinforced to resist horizontal stresses, then the structural stability improves, but the device complexity increases

Engineering Contradiction:
Improvestructural stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent employs a circular part extending horizontally around the vertical spring. This curved, circular geometry provides inherent structural strength to resist horizontal stresses while maintaining a simple, elegant form. The circular shape distributes stresses evenly and provides rigidity without requiring complex angular joints or multiple discrete reinforcement elements.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Volume of moving object

If the spring dimensions are reduced to minimize dead volumes, then the space efficiency improves, but the load-bearing capacity decreases

Engineering Contradiction:
Improvespring dimensionsVSAvoidload-bearing capacity
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The patent compensates for reduced vertical spring dimensions by adding horizontal reinforcement through the circular beam portion. This dimensional transition from vertical to horizontal reinforcement allows the use of more compact springs while maintaining overall load-bearing capacity through the combined structural system.

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