Solution Overview

Problem

The existing push tube assemblies for off-road vehicles are not universally compatible due to differences in pivot bracket spacing, preventing assemblies from one manufacturer from being mounted on mounts from other manufacturers, limiting versatility.

Innovation Solution

A push tube adapter with a rectangular flat adapter plate and pivotally secured mounting brackets that can be positioned to accommodate different pivot bracket spacings, allowing the rearward end of the push tube assembly to be securely attached to various mounts under an off-road vehicle, including those from CCAC, Warn, and Moose.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manufacturers use different pivot bracket spacings for their mounts, then each manufacturer's push tube assembly is optimized for its specific mount, but compatibility across different manufacturers' mounts is lost

Engineering Contradiction:
Improvepivot bracket spacingVSAvoidmount compatibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The adapter plate is designed with multiple sets of bolt openings at different spacings (first pair and second pair of bolt openings) to accommodate different pivot bracket spacings from various manufacturers. This allows a single adapter plate to interface with multiple mount types (CCAC, Warn, Moose) while maintaining precise alignment for each specific spacing requirement.

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

Solution Approach 2:

The adapter plate incorporates variable spacing parameters through its multiple pairs of bolt openings. The first pair of bolt openings is positioned at a first spacing to match one manufacturer's pivot bracket spacing, while the second pair is positioned at a second spacing to match another manufacturer's spacing, enabling the same adapter to adapt to different dimensional parameters.

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If push tube assemblies are designed with fixed pivot bracket spacing, then manufacturing is simplified, but the ability to mount on different manufacturer's mounts is prevented

Engineering Contradiction:
Improvepush tube assembly productionVSAvoidmount interchangeability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The mounting system is divided into separate functional components: the push tube assembly with its fixed pivot brackets, the adapter plate with multiple bolt opening configurations, and the mount with its specific pivot bracket spacing. This segmentation allows each component to be manufactured independently with fixed dimensions while the adapter provides the flexibility to combine them in multiple configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter plate serves as an intermediary component between the push tube assembly and the mount. It translates between different pivot bracket spacing requirements by providing multiple pairs of bolt openings at different spacings, allowing the push tube assembly to interface with various mount types without requiring redesign of the push tube itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple adapter configurations are created for different mounts, then compatibility with various mounts is achieved, but device complexity increases

Engineering Contradiction:
Improvemount compatibilityVSAvoidadapter design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple adapter configurations for different mount spacings are merged into a single adapter plate by incorporating multiple pairs of bolt openings at different spacings on the same plate. This consolidation allows the user to select the appropriate bolt opening pair for each mount type without requiring multiple separate adapter plates, reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)
