Solution Overview

Problem

The mismatch between drive system components with constant dimensions and skid steer loader frames with varying dimensions leads to assembly distortion and increased installation time, as existing solutions fail to account for dimensional differences.

Innovation Solution

A mounting method for skid steer loaders that includes a fixed coupling for one end of a component and a variable coupling, such as a compression sleeve arrangement, for the other end, allowing for dimensional adjustments between the component and the frame to accommodate varying frame dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If fixed coupling is used to mount drive components on skid steer loader frames, then assembly precision is improved, but frame distortion occurs due to dimensional mismatches

Engineering Contradiction:
Improvemounting precisionVSAvoidframe structural integrity
Core Design Contradiction:
Manufacturing precisionVSStability of the object's composition

Solution Approach 1:

The mounting system is segmented into a fixed coupling at one end and a variable coupling at the other end. This segmentation allows one end to provide precise positioning while the other end accommodates dimensional variations, preventing frame distortion while maintaining mounting precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The variable coupling introduces dynamic adjustability to the mounting system, allowing it to adapt to dimensional variations in the frame. This dynamic element compensates for manufacturing tolerances and prevents the frame from distorting while maintaining proper component alignment.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If variable coupling is used at both ends of the component, then adaptability to dimensional variations is improved, but mounting precision deteriorates

Engineering Contradiction:
Improvedimensional compatibilityVSAvoidmounting precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The mounting system is divided into fixed and variable coupling sections. The fixed coupling provides precise positioning and reference points, while the variable coupling provides adaptability. This segmentation ensures both precision and dimensional compatibility are achieved.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If fixed coupling is used at both ends, then structural stability is improved, but assembly time increases due to frame distortion

Engineering Contradiction:
Improveframe stabilityVSAvoidassembly time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The variable coupling provides dynamic adjustment capability that allows the component to be mounted without forcing the frame into distortion. This maintains frame stability while significantly reducing assembly time by eliminating the need for corrective adjustments or rework.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If dimensional variations in frames are accommodated, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvedimensional compatibilityVSAvoidmounting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting system is segmented into fixed and variable coupling portions, which keeps the complexity manageable by dividing the adaptation function into discrete, simple elements rather than requiring a completely complex adjustable mechanism.

Inventive Principle:
Principle #1Segmentation

AI summary

A mounting method for a skid steer loader is disclosed including coupling a first end portion of a component directly to a first wall of a skid steer loader frame. The method also includes coupling a second end portion of the component to an opposite wall of the skid steer loader frame by a mounting system that allows for dimensional differences between the component and the skid steer loader frame.
