Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a tow hook is fixedly disposed on a rear bumper with load concentrated at a single point, then the structure is simple, but the connection stability is poor
Solution Approach 1:
The towing hook structure is segmented into multiple components: a towing ball body, a towing arm with hinge connection, and a stabilizing support. This segmentation allows each component to perform its specific function while collectively improving connection stability through distributed load bearing and geometric stabilization.
Solution Approach 2:
The invention introduces a new dimension of stabilization by adding a support element that extends from the towing arm to the ground or a lower point on the towing vehicle. This creates a triangular stable structure in three-dimensional space, transforming the unstable single-point connection into a stable multi-point spatial structure.
2Ease of operation
If a towing ball body is connected through a pin shaft in a vertical slot, then the structure is simple, but the towing ball body cannot move back and forth for steering and position adjustment is not flexible
Solution Approach 1:
The towing ball body is transformed from a static fixed position to a dynamic adjustable position. The movable connection between the towing ball body and the towing arm allows the ball to move back and forth along the towing arm and rotate, enabling flexible steering and position adjustment while maintaining structural simplicity.
3Productivity
If a towing hook device has fixed position, then the structure is simple, but the installation and disassembly time is prolonged and work efficiency is low
Solution Approach 1:
The towing hook device incorporates dynamic elements including a movable towing ball body that can slide along the towing arm and a collapsible towing arm that can be folded. These dynamic features enable rapid deployment and retrieval, significantly reducing installation and disassembly time while maintaining structural simplicity.

AI summary
A steerable towing hook device includes a towing ball body and a towing arm. The towing ball body includes a towing ball and a towing ball mount. The towing arm includes a hitch arm and a fixed arm, and the fixed arm is provided with a square steel configured to connect to a vehicle receiver. The towing ball mount is fixedly connected to an outer back of the hitch arm. The hitch arm is provided with a moving-steering device configured to move and steer the towing ball mount, and the hitch arm is snap-fitted the fixed arm through the device for moving and steering the towing ball mount. A steerable towing hook device with a rational structure and strong practicality enables the towing ball body to move back and forth to steer, adjusts a position of the towing hook flexibly, is convenient to use, and improves work efficiency.
