Solution Overview

Problem

Designing machine platforms that can accommodate different hardware options without significant cost increases or performance sacrifices, particularly in rugged environments where traditional mounting strategies are inflexible and customer-specific.

Innovation Solution

Implementing adapter mechanisms with specific connecting interfaces to couple body and frame components with various suspension elements, allowing for the use of different suspension types on identical machine components, and providing kits for replacing suspension elements with vibration isolation devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional purpose-built mounting strategies are used for coupling operator cab with frame, then structural integrity and robustness are maintained, but flexibility to accommodate different suspension types is lost

Engineering Contradiction:
Improveflexibility to accommodate different suspension typesVSAvoidmounting strategy complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting kit provides a universal solution that can accommodate multiple types of suspensions (e.g., rubber block, spring, viscous) using the same basic mounting elements and fastening mechanisms, allowing a single design to serve multiple functions across different suspension configurations

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

Solution Approach 2:

The mounting kit acts as an intermediary component between the operator cab and various suspension types, providing standardized mounting elements, adapter plates, and fastening mechanisms that interface with different suspension configurations without requiring custom designs for each suspension type

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If different machine platforms are designed purpose-built for specific suspension types, then performance and integrity are optimized, but manufacturing costs and platform variety increase

Engineering Contradiction:
Improvemanufacturing costVSAvoidstructural integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The mounting system is segmented into separate, interchangeable components including mounting elements, adapter plates, and fastening mechanisms that can be selectively assembled to match different suspension types, allowing standardized production of each component while maintaining overall structural integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting kit accommodates different suspension types by changing configurable parameters such as mounting element configuration, adapter plate geometry, and fastening mechanism selection, rather than requiring completely different platform designs for each suspension type

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If robust and rigid mounting strategies are used, then structural integrity is maintained, but adaptability to different hardware configurations is reduced

Engineering Contradiction:
Improvehardware configuration flexibilityVSAvoidmounting hardware complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting system incorporates dynamic adjustability through selectable mounting elements and configurable fastening mechanisms that can be adapted to different suspension configurations while maintaining robust structural connections, allowing the same hardware to serve multiple configuration needs

Inventive Principle:
Principle #15Dynamics

AI summary

A method for making machines includes selecting one of a plurality of types of suspension elements for coupling between a body component and a frame component of a machine. If the suspension elements are of a first type, they are coupled with mounting elements on the body component having a configuration corresponding therewith. If the suspension elements are of a second type, they are coupled with mounting elements on the frame component which have a configuration corresponding therewith. Adapter mechanisms having a first connecting interface corresponding to mounting elements on one of the body component and frame component, and a second connecting interface corresponding with the selected suspension elements, are used to couple the body component with the frame component. A group of machines includes a first set using the first type of suspension elements coupled between the body component and frame component, and a second machine set which includes the second type of suspension elements coupled between a body component and frame component.
