Solution Overview

Problem

Existing damping modules with a vertical layout in mobile apparatuses result in increased height, limiting space utilization and stability, especially due to the need for large compression springs to achieve damping, which also restricts the use space and mobility.

Innovation Solution

A horizontal layout damping module with a double-spring mechanism, including a bearing member, bent arm bracket, swinging bent arm, transmission member, and damping mechanism, which reduces the height and space occupied, while maintaining damping effectiveness and improving stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a vertical damping module with compression spring is used, then damping function is achieved, but the height of mobile apparatus increases

Engineering Contradiction:
Improvedamping functionVSAvoidheight of mobile apparatus
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The patent transforms the damping module from a vertical layout to a horizontal layout, changing the spatial dimension in which the damping mechanism operates. The bearing member extends horizontally instead of vertically, and the swinging bent arm pivots horizontally, thereby reducing the height occupation while maintaining the damping function through the same compression spring mechanism.

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

2Reliability

If a large compression spring is used to achieve damping, then damping effectiveness is improved, but space utilization rate decreases

Engineering Contradiction:
Improvedamping effectivenessVSAvoidspace utilization rate
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

By reorienting the damping module from vertical to horizontal configuration, the patent allows the compression spring to operate in the horizontal dimension rather than occupying vertical space. This dimensional transformation enables the mobile apparatus to maintain effective damping while improving space utilization, particularly in the vertical dimension where other components can now be positioned more efficiently.

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

3Reliability

If a vertical damping module is used, then damping is achieved, but the center of gravity is raised

Engineering Contradiction:
ImprovedampingVSAvoidstability of mobile apparatus
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent relocates the damping module from a vertical configuration to a horizontal configuration, which lowers the center of gravity of the mobile apparatus. The bearing member and swinging bent arm are positioned horizontally, allowing the compression spring to provide damping forces without elevating the overall center of gravity, thereby improving stability.

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

4Length of stationary object

If a horizontal layout damping module is used, then height is reduced and space utilization is improved, but structural complexity increases

Engineering Contradiction:
Improveheight of mobile apparatusVSAvoidstructural complexity
Core Design Contradiction:
Length of stationary objectVSDevice complexity

Solution Approach 1:

The patent divides the damping module into distinct functional segments: a bearing member with left and right assembly portions, a swinging bent arm with upper and lower end portions, and a transmission member. This segmentation allows each component to perform its specific function in the horizontal layout, making the overall structure more manageable and easier to assemble while maintaining reduced height.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The horizontal layout reconfigures the spatial relationships between components, placing the bearing member horizontally with assembly portions spaced apart, and positioning the swinging bent arm to pivot horizontally. This dimensional change simplifies the vertical space requirements while the modular segmentation of components keeps the structural complexity manageable through clear functional separation.

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