Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing stoppers for machine implements wear out quickly due to impact forces and lack versatility across different machines and terrain conditions, requiring frequent maintenance and custom-made solutions.

Innovation Solution

A stopper assembly with a mount and adjustable structure that allows pivotal coupling to either the implement or machine frame, featuring an engagement structure and spacer plates to restrict movement and adjust distance, enabling standardization and reduced wear.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed stopper is used to control pivotal movement of the implement, then the pivotal movement is restricted, but the stopper wears out quickly due to significant impact forces

Engineering Contradiction:

Improvepivotal movement controlVSAvoidstopper service life

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The stopper is made pivotally coupled to the mount instead of being fixed, allowing it to dynamically adjust its position and absorb impact forces through controlled movement, thereby reducing wear and extending service life while maintaining pivotal movement control

Inventive Principle:

Principle #15Dynamics

2Reliability

If custom-made stoppers are used to fit individual bucket/frame combinations, then the fit and control are precise, but the complexity and cost increase

Engineering Contradiction:

Improvefit precisionVSAvoidstopper variety

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The stopper assembly is designed with adjustable features including multiple mounting positions, interchangeable spacer plates, and adjustable stopper angles, allowing a single standardized design to fit various bucket and frame combinations, thereby reducing the need for custom-made stoppers while maintaining precise control

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If regular maintenance and replacement of stoppers is performed, then the machine operates safely, but the operating cost increases

Engineering Contradiction:

Improvemachine safetyVSAvoidoperating cost

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The pivotal coupling allows the stopper to dynamically absorb and distribute impact forces, reducing wear and extending service life, thereby reducing the frequency of maintenance and replacement while maintaining machine safety

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The adjustable and standardized design allows the same stopper assembly to be used across different machine configurations, reducing inventory requirements and replacement costs while maintaining safety standards

Inventive Principle:

Principle #6Universality (Multi-functionality)
