Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing rope guide protective shells for automobile winches have stability issues due to adhesive connections and are inconvenient to mount and detach using bolt connections.

Innovation Solution

A plug-in rope guide protective shell design featuring a shell body with an inner cavity and a plug-in member that inserts into a guide opening, providing a stable and easy-to-mount connection with the rope guide.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If adhesive connection is used to mount the protective shell, then the mounting process is simple, but the connection stability is poor and the protective shell tends to fall off

Engineering Contradiction:

Improvemounting simplicityVSAvoidconnection stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the adhesive connection method with a mechanical plug-in connection system. The plug-in member inserted into the guide opening creates a mechanical interlock that provides both easy installation and reliable connection stability, eliminating the need for adhesives and their associated reliability issues.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The plug-in member acts as an intermediary element between the protective shell and the rope guide. This intermediary component transfers and distributes connection forces, providing stable mechanical coupling while maintaining ease of assembly and disassembly operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If bolt connection is used to mount the protective shell, then the connection stability is improved, but the mounting and detachment process becomes inconvenient

Engineering Contradiction:

Improveconnection stabilityVSAvoidmounting convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The connection system is segmented into distinct functional components: the plug-in member on the protective shell and the corresponding guide opening in the rope guide. This segmentation allows for simple, tool-free assembly while maintaining bolt-level connection stability through the mechanical interlock geometry.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The plug-in connection provides dynamic ease of operation through simple insertion and withdrawal motions, while the mechanical interlock geometry ensures static connection stability during operation. The system transitions from a static adhesive bond or complex bolt assembly to a dynamic yet secure mechanical interface.

Inventive Principle:

Principle #15Dynamics
