Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing trailers used for removing and arranging bundles from heat exchangers require a tractive vehicle for support, occupying excessive space and limiting their independent operation.

Innovation Solution

A trailer equipped with a support wheel axle that can be connected to the trailer in an uncoupled state, allowing independent support and enabling self-propelled movement, combined with a drive system for efficient alignment and steerable wheels for efficient operation without a tractive vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a trailer is used for bundle extraction without a tractive vehicle, then space requirements are reduced and operational independence is improved, but the trailer lacks sufficient support and mobility

Engineering Contradiction:

Improveoperational independenceVSAvoidsupport stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies the dynamics principle by making the wheel axle configuration changeable. The trailer can be equipped with different numbers and positions of wheel axles depending on whether it is coupled to a tractive vehicle or operating independently. This dynamic reconfiguration allows the trailer to maintain stability and mobility in both operational modes, resolving the contradiction between operational independence and support stability.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a tractive vehicle is coupled to the trailer, then the trailer gains stable support and mobility, but space requirements increase and operational flexibility is reduced

Engineering Contradiction:

Improvesupport stabilityVSAvoidspace occupation

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent applies segmentation by separating the support and mobility functions from the tractive vehicle to the trailer itself through the addition of wheel axles. This allows the trailer to function as a self-contained unit with its own support system, eliminating the need for a constantly coupled tractive vehicle and thereby reducing space occupation while maintaining stability when needed.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If the trailer is equipped with a fixed wheel axle configuration, then structural simplicity is maintained, but adaptability to different operational modes is reduced

Engineering Contradiction:

Improvestructural simplicityVSAvoidoperational mode flexibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent makes the wheel axle configuration dynamic rather than fixed. The trailer can be equipped with different numbers and positions of wheel axles depending on operational requirements. This dynamic approach maintains structural simplicity in each specific configuration while providing adaptability across different operational modes, resolving the contradiction between simplicity and flexibility.

Inventive Principle:

Principle #15Dynamics
