Solution Overview

Problem

Existing lifting devices for vehicles face challenges in securely connecting the lifting bracket to the suspension bracket without rotation, requiring complex assembly and precise machining, which is costly and time-consuming.

Innovation Solution

A connection system utilizing an anchor plate with a step-shaped recess and a complementary straight connection end on the lifting bracket, eliminating the need for anchoring bushings and semicircular ends, allowing direct assembly and improved stress absorption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If anchoring bushings and semicircular ends are used to prevent rotation, then reliability of connection is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveconnection stabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the anchoring bushings from the connection system, replacing them with a step-shaped recess directly formed on the anchor plate. This extraction of the intermediate component simplifies the overall device structure while maintaining the anti-rotation function through the geometric design of the step recess that complements the protruding shape on the lifting bracket.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the anti-rotation feature directly into the anchor plate by forming a step-shaped recess, merging the functions of the anchor plate and the previously separate anchoring bushing into a single integrated component. This reduces the number of parts and simplifies manufacturing while ensuring reliable connection.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If precise machining of semicircular ends is performed, then connection reliability is improved, but manufacturing cost and time increase

Engineering Contradiction:
Improveconnection stabilityVSAvoidmanufacturing simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The connection interface is segmented into discrete geometric features: a step-shaped recess with specific dimensions on the anchor plate and a corresponding protruding shape on the lifting bracket. This segmentation into standardized geometric elements allows for simpler manufacturing processes compared to precise semicircular machining, while maintaining reliable anti-rotation connection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs a simpler, more cost-effective anchor plate design with step-shaped recesses that can be manufactured using less expensive processes. This replaces the need for expensive precision machining of semicircular ends, reducing manufacturing cost and time while achieving the same functional result of preventing rotation.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If multiple intermediate components are used for connection, then connection reliability is improved, but assembly speed decreases

Engineering Contradiction:
Improveconnection stabilityVSAvoidassembly speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent extracts and removes the intermediate anchoring bushings from the assembly process, reducing the number of components that need to be handled and installed. This directly increases assembly speed while maintaining connection reliability through the integrated step-shaped recess design on the anchor plate.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

By merging the anchoring function into the anchor plate itself through the step-shaped recess, the patent reduces the number of assembly steps. The lifting bracket can be directly connected to the anchor plate without installing separate bushings, significantly accelerating the assembly process while ensuring reliable anti-rotation connection.

Inventive Principle:
Principle #5Merging (Combining)
