Solution Overview

Problem

Current towing assemblies face challenges in simultaneously extracting vehicles from inaccessible locations and safely towing them on roads, as they often require manual locking and operation, and lack an automated mechanism for converting between flexible and rigid configurations.

Innovation Solution

A towing assembly with an automated locking mechanism and operating mechanism that allows for conversion between articulated and rigid positions, featuring a hitch with pivotally attached members and joints that can be automatically locked in place, enabling safe and efficient towing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a supple and flexible assembly is used to extract vehicles from inaccessible locations, then the ability to reach difficult locations is improved, but the safety and security for towing on roads deteriorates

Engineering Contradiction:
Improveability to reach difficult locationsVSAvoidsafety for towing on roads
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The towing assembly incorporates an automated mechanism that dynamically transforms the structure between a flexible articulated configuration (for reaching inaccessible locations) and a rigid triangular configuration (for safe road towing). The system automatically adjusts its mechanical properties based on the operational phase, resolving the contradiction between adaptability and reliability.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a rigid triangular assembly is used for safe road towing, then the safety and security for towing is improved, but the ability to extract vehicles from inaccessible locations deteriorates

Engineering Contradiction:
Improvesafety for towing on roadsVSAvoidability to extract vehicles
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The assembly automatically transforms from a rigid triangular structure to a flexible articulated structure through an automated mechanism, enabling it to adapt between the safety requirements of road towing and the accessibility requirements of extraction operations.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If manual locking mechanism is used, then the device complexity is reduced, but the ease of operation and safety deteriorates due to required manual intervention

Engineering Contradiction:
Improvelocking mechanism complexityVSAvoidautomatic positioning
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The locking mechanism is designed to automatically lock and unlock the towing assembly at the appropriate positions without requiring manual intervention. The system self-regulates its locking state based on its configuration, eliminating the need for user operation while maintaining simplicity in the mechanical design.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If automated locking mechanism is implemented, then the ease of operation and safety are improved, but the device complexity increases

Engineering Contradiction:
Improveautomatic lockingVSAvoidlocking mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The automated locking mechanism operates autonomously based on the assembly's configuration, automatically engaging locks when in rigid triangular form and disengaging when in flexible articulated form, providing ease of operation without requiring complex control systems.

Inventive Principle:
Principle #25Self-service

5Ease of operation

If automated operating mechanism is implemented, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveautomatic operationVSAvoidoperating mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The automated operating mechanism enables the towing assembly to automatically transform between configurations and lock/unlock as needed, operating autonomously without user intervention while maintaining reasonable mechanical complexity through self-regulating design.

Inventive Principle:
Principle #25Self-service
