Solution Overview

Problem

Existing anti-vibration systems for motor vehicles are prone to accidental fall due to single-point fixation, posing risks to pedestrians and material damage, and existing dual-screw solutions are bulky, difficult to install, and require unnecessary tools.

Innovation Solution

A mounting device with a slider and protrusion system that provides two secure attachment points on the vehicle body, allowing lateral sliding and tool-free installation, using a soft iron core, magnetic coil, and rubber spring for vibration maintenance, along with a non-return mechanism to prevent accidental disengagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single screw is used to fix the actuator, then the device complexity is reduced, but the reliability of mounting is insufficient and accidental fall risk increases

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

Solution Approach 1:

The mounting device is segmented into two distinct attachment mechanisms: a screw connection for primary fixation and a protrusion-slider mechanism for secondary anchoring. This segmentation allows each component to perform its specific function independently, achieving reliable dual-point fixation without requiring a complex integrated system. The actuator body is divided into a soft iron core and a protrusion extension, enabling separate attachment methods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The slider acts as an intermediary element between the protrusion and the vehicle body wall. It provides a simple receptacle that receives the protrusion laterally and prevents disengagement, while requiring no tools for operation. The slider mediates the connection by converting a simple lateral insertion motion into a secure mechanical constraint.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If two screws are used to fix the actuator, then the reliability of mounting is improved, but the device complexity and size increase

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

Solution Approach 1:

The mounting system is divided into two attachment points: a screw connection for primary fixation and a protrusion-slider mechanism for secondary anchoring. This segmentation allows each component to perform its specific function independently, achieving reliable dual-point fixation without requiring a complex integrated system. The actuator body is divided into a soft iron core and a protrusion extension, enabling separate attachment methods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protrusion-slider mechanism replaces the need for a second screw and screwdriver. Instead of using a threaded mechanical fastener requiring rotational motion and tools, the design uses a lateral insertion motion where the protrusion simply slides into the slider receptacle. This substitution eliminates the complexity of a second screw-fastening system while maintaining dual-point attachment reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If two screws with large center distance are used, then the reliability is improved, but the ease of operation deteriorates due to tool accessibility issues

Engineering Contradiction:
Improvemounting reliabilityVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The protrusion-slider mechanism replaces the need for a second screw and screwdriver. Instead of using a threaded mechanical fastener requiring rotational motion and tools, the design uses a lateral insertion motion where the protrusion simply slides into the slider receptacle. This substitution eliminates the complexity of a second screw-fastening system while maintaining dual-point attachment reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The protrusion is self-guiding and self-locking within the slider. Once the protrusion is laterally inserted into the slider receptacle, the geometry of the fit automatically prevents reverse motion and secures the actuator. This self-service mechanism eliminates the need for tools, adjustment, or complex alignment procedures during installation.

Inventive Principle:
Principle #25Self-service

4Device complexity

If a compact mounting device is used, then the device complexity is reduced, but the reliability of preventing accidental fall decreases

Engineering Contradiction:
Improvemounting device complexityVSAvoidmounting reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The mounting system is divided into two attachment points: a screw connection for primary fixation and a protrusion-slider mechanism for secondary anchoring. This segmentation allows each component to perform its specific function independently, achieving reliable dual-point fixation without requiring a complex integrated system. The actuator body is divided into a soft iron core and a protrusion extension, enabling separate attachment methods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The slider is integrated directly into the vehicle body wall structure, merging the mounting function with the existing body architecture. The protrusion is integrated as an extension of the actuator's soft iron core, combining the magnetic core function with the mechanical attachment function. This merging achieves reliable dual-point fixation without adding separate, complex mounting hardware.

Inventive Principle:
Principle #5Merging (Combining)
