Solution Overview

Problem

Rigidly mounting non-metal panels to a metal frame in work vehicles leads to cracking and weakening due to vibrations and stress, and requires adjustments for tolerance alignment, which is challenging.

Innovation Solution

A vibration isolator device with a metal member affixed to the non-metal panel, an isolator mount plate allowing adjustment in at least two directions, and a vibration isolator positioned between the metal member and frame, providing additional adjustment in a third direction for secure assembly and vibration isolation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If non-metal panels are rigidly mounted to a metal frame, then structural strength is improved, but vibration-induced cracking and panel weakening occur

Engineering Contradiction:
Improvestructural strengthVSAvoidpanel integrity
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

A vibration isolator is introduced as an intermediary element between the metal frame and non-metal panel. This isolator absorbs and dampens vibrations, preventing them from being transmitted to the panel while maintaining secure attachment. The isolator acts as a mediator that decouples the rigid connection, thereby preserving both structural strength and panel integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mounting system transitions from a rigid fixed connection to a flexible adjustable connection. The isolator and adjustment mechanism allow for parameter changes in position and orientation, enabling the panel to accommodate vibrations and misalignments without cracking, thus maintaining reliability while preserving structural support.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If non-metal panels are rigidly mounted to a metal frame, then structural stability is improved, but stress-induced cracking occurs

Engineering Contradiction:
Improvestructural stabilityVSAvoidpanel durability
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The vibration isolator serves as a stress-absorbing intermediary between the metal frame and non-metal panel. It reduces the transmission of stress forces to the panel, preventing stress-induced cracking while maintaining the overall stability of the mounted structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mounting system incorporates dynamic adjustment capabilities, allowing the panel position to be adjusted in multiple directions. This dynamic adaptability enables the system to compensate for stress and misalignment, maintaining structural stability while preventing panel damage.

Inventive Principle:
Principle #15Dynamics

3Strength

If non-metal panels are rigidly mounted to a metal frame, then assembly strength is improved, but alignment adjustment becomes difficult

Engineering Contradiction:
Improveassembly strengthVSAvoidalignment adjustment
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The mounting system incorporates adjustable elements that allow for movement and repositioning of the non-metal panel in multiple directions. These dynamic adjustment mechanisms enable easy alignment during installation while maintaining secure attachment, thus improving ease of operation without compromising assembly strength.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting system is divided into separate adjustable components, including the isolator and positioning mechanisms. This segmentation allows for independent adjustment of each component to achieve proper alignment, making the assembly process easier while maintaining overall structural strength.

Inventive Principle:
Principle #1Segmentation

4Strength

If non-metal panels are rigidly mounted to a metal frame, then structural support is improved, but vibration isolation is insufficient

Engineering Contradiction:
Improvestructural supportVSAvoidvibration transmission
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

A vibration isolator is positioned between the metal frame and non-metal panel to act as a mediator that absorbs and dampens vibrations. This isolator provides effective vibration isolation while maintaining the structural support function, preventing harmful vibrations from reaching the panel.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mounting system transitions from a rigid fixed connection to a flexible connection with vibration-damping properties. The isolator introduces parameter changes in terms of vibration absorption and energy dissipation, effectively reducing harmful vibrations while preserving structural support.

Inventive Principle:
Principle #35Parameter changes
