Solution Overview

Problem

Conventional vehicle towing trailers are cumbersome for storage and difficult to load, requiring substantial space and often necessitating steep ramps that are challenging for a single user to manage.

Innovation Solution

A portable towing system with wheel assemblies that allow the towing frame to be raised and lowered, enabling easy assembly and disassembly, compact storage, and single-user operation, featuring a modular design with adjustable components for versatile vehicle loading and transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional towing trailers use fixed chassis designs, then structural stability is maintained, but storage space requirements increase and loading difficulty worsens

Engineering Contradiction:
Improveloading easeVSAvoidchassis structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The towing trailer is divided into modular components including a removable support platform, separable wheel assemblies, and detachable frame sections. This segmentation allows the trailer to be disassembled into compact parts for easy storage and transported in smaller quantities, while maintaining structural integrity when assembled for towing operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The trailer incorporates adjustable and movable elements such as height-adjustable legs, collapsible frame sections, and reconfigurable support structures. These dynamic features enable the trailer to transform between a stable towing configuration and a compact storage configuration, improving both operational flexibility and storage efficiency.

Inventive Principle:
Principle #15Dynamics

2Reliability

If towing trailers are designed for heavy-duty transport, then load capacity is improved, but weight and storage difficulty increase

Engineering Contradiction:
Improvetowing capabilityVSAvoidstorage volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The heavy-duty towing capability is achieved through modular construction where robust frame sections and high-strength components can be assembled only when needed. Individual modules can be stored separately in compact spaces, and the complete high-capacity structure is formed only during actual towing operations, reducing storage volume requirements while maintaining towing reliability.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If single-user operation is enabled, then user accessibility is improved, but device complexity increases

Engineering Contradiction:
Improveuser accessibilityVSAvoidmechanism structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The trailer incorporates self-leveling mechanisms, automatic locking features, and intuitive assembly guides that allow a single user to operate the system without requiring complex manual adjustments or assistance from others. The design includes self-explanatory controls and automated safety features that simplify operation while maintaining structural complexity only where necessary for functionality.

Inventive Principle:
Principle #25Self-service

AI summary

A portable towing system for a motorcycle or similar vehicle, such as a trike, the frame of which can be lowered to ground level to facilitate loading of the motorcycle or similar vehicle by pushing or riding the vehicle onto the frame without risk of the vehicle falling off the sides of a steeply inclined ramp. The towing system may be assembled, raised, lowered, and disassembled by a single person, if desired. The raising and lowering of the frame is effected by a lifting and lowering mechanism connected with the wheel assemblies.
