Solution Overview
Problem
Conventional vehicle towing systems are hazardous, time-consuming, prone to equipment failure, and limited in tension capacity, posing risks to users during connection and disconnection, and requiring multiple systems for heavy vehicles.
Innovation Solution
A towing system comprising a first member attached to a towing vehicle's drawbar, a second member pivotally connected with a cam unit for centering, and a third member that can be pivoted into a raised storage position, featuring a catch unit for secure attachment to the towed vehicle, utilizing hydraulic actuators for efficient and safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional towing systems use elongated flexible members with hooks, then the system is simple in structure, but users are exposed to dangerous situations during connection and disconnection
Solution Approach 1:
The patent introduces a towing assembly as an intermediary device between the towing vehicle and towed vehicle. This assembly includes a housing with a receiving chamber that safely contains the flexible member, and a release mechanism that automates the connection and disconnection process, eliminating the need for users to manually handle the flexible member and hooks, thus resolving the safety hazard while maintaining structural simplicity
Solution Approach 2:
The release mechanism is designed to be actuated by the towing vehicle's movement itself. When the towing vehicle moves forward, the flexible member tensions and automatically triggers the release mechanism to disengage the hook from the towing assembly, eliminating the need for manual intervention during disconnection and thereby improving user safety
2Ease of operation
If conventional towing systems use manual connection and disconnection, then the system is simple to operate, but the process is time consuming
Solution Approach 1:
The towing assembly is pre-configured with the flexible member and release mechanism before use. The housing is designed with a receiving chamber that automatically positions and secures the flexible member, so when towing is needed, the system is already prepared for immediate connection, eliminating the time-consuming manual assembly process while keeping operation simple
Solution Approach 2:
The patent replaces manual mechanical connection and disconnection operations with an automated release mechanism that uses the tension in the flexible member to trigger automatic disengagement. This substitution of manual mechanical operations with an automated mechanical system reduces the time required for connection and disconnection while maintaining ease of operation through simple actuation
3Device complexity
If conventional towing systems use single flexible member, then the system is simple, but the potential for breaking exists and tension capacity is limited
Solution Approach 1:
The patent segments the towing system into multiple functional components: a housing structure, a flexible member, a release mechanism, and a towing assembly. This segmentation allows each component to be optimized for its specific function, with the housing protecting the flexible member from damage and the release mechanism ensuring controlled disengagement, thereby improving reliability without significantly increasing overall system complexity
Solution Approach 2:
The housing with its receiving chamber provides beforehand protection for the flexible member, cushioning it from environmental damage and accidental damage during storage and transport. This prior protection reduces the risk of equipment failure before the towing operation even begins, improving reliability while maintaining a relatively simple system configuration
4Force
If conventional towing systems use elongated flexible member under tension, then the system can handle towing loads, but physical injury risk occurs when the member breaks
Solution Approach 1:
The housing acts as an intermediary protective structure between the high-tension flexible member and the surrounding environment. When the flexible member is under tension during towing, the housing contains it safely, and if the member were to break, the housing would contain the failure and prevent the broken ends from causing physical injury to users or nearby objects, thus allowing high towing capacity while reducing injury risk
5Device complexity
If conventional towing systems are designed for light-duty towing, then the system is simple and lightweight, but multiple systems are required for heavy vehicles
Solution Approach 1:
The towing assembly is designed as a universal system that can handle a wide range of towing capacities. The housing and release mechanism are engineered to accommodate flexible members of different strengths and lengths, allowing the same basic assembly design to serve both light-duty and heavy-duty towing needs. This multi-functionality eliminates the need for multiple specialized systems while maintaining relatively simple configuration
