Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wrench is used to rotate the shaft product or screw rod for angle adjustment, then the device can be adjusted to a corresponding angle, but the wrench can only rotate within a range of 180° and needs to rotate back and forth repeatedly, resulting in low efficiency and long installation time
Solution Approach 1:
The patent applies the dynamics principle by transforming the static 180° limited wrench rotation into a dynamic 360° continuous rotation mechanism. The telescoping rod assembly with gear set enables the wrench to rotate continuously in one direction through 360°, eliminating the need for back-and-forth repeated rotations. This dynamic transformation resolves the contradiction by allowing full rotational freedom while reducing adjustment time.
Solution Approach 2:
The patent introduces a telescoping rod assembly with gear set as an intermediary mechanism between the wrench and the shaft product. This intermediary component translates the wrench's rotational motion into the desired angular adjustment while enabling 360° continuous rotation. The gear set acts as a mediator that converts the input rotation into controlled output movement, resolving the limitation of direct wrench rotation.
2Productivity
If the wrench rotates back and forth repeatedly within 180° to reach the corresponding angle, then the angle adjustment can be achieved, but the efficiency is low
Solution Approach 1:
The patent implements continuity of useful action by enabling the wrench to rotate continuously through 360° in one direction without needing to reverse or pause. The telescoping rod assembly maintains continuous rotational motion throughout the adjustment process, eliminating the intermittent back-and-forth movements. This continuous action improves productivity by reducing the number of operational cycles required.
Solution Approach 2:
The dynamic mechanism allows the system to adapt its motion pattern from limited 180° oscillation to continuous 360° rotation. The telescoping rod assembly with gear set provides dynamic motion control that maintains optimal rotational velocity throughout the adjustment process, improving operational efficiency and reducing the complexity of repeated positioning operations.

AI summary
Provided is a vehicle wheel stopper. The vehicle wheel stopper includes a bracket, clamping jaws and a telescoping rod assembly. The clamping jaws include a first clamping jaw and a second clamping jaw. Both the first clamping jaw and the second clamping jaw are pivotally connected to the bracket. The telescoping rod assembly includes a telescoping rod set and a gear set. The gear set drives the telescoping rod set to rotate around an axis of the telescoping rod set, and the telescoping rod set simultaneously drives the first clamping jaw and the second clamping jaw so that the first clamping jaw and the second clamping jaw separately have a first state of simultaneously clamping the two spaced wheels and a second state of simultaneously loosening the two spaced wheels. In this device, the wrench rotates the gear set within a range of 360° to further drive the support rod.
