Solution Overview

Problem

Existing mounting devices for motor vehicle components, such as anti-vibration systems, often become inaccessible for disassembly due to cluttered environments, making it difficult to dismantle parts once installed under the hood, especially when covered by other components or materials.

Innovation Solution

A mounting device featuring an intermediate piece with three fixing screws, where two screws secure the part to the vehicle body and the third screw connects the actuator to the intermediate piece, allowing for easy installation and disassembly via different access routes, with the screws designed to occupy minimal space and require simple machining.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws are used to secure the actuator, then reliable attachment is achieved, but space occupation and manufacturing complexity increase

Engineering Contradiction:
Improveattachment reliabilityVSAvoidmounting device complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The intermediate piece serves multiple functions: it provides attachment points for screws, maintains spacing between the actuator and vehicle body, and enables access from both sides. This multi-functionality reduces the need for additional components, thereby reducing overall device complexity while maintaining reliable attachment

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The screw heads are positioned within the intermediate piece structure, with the intermediate piece nesting between the actuator and the vehicle body. This nested arrangement minimizes space occupation while maintaining secure attachment through the screw-fastened connection

Inventive Principle:
Principle #7Nested doll (Nesting)
