Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing anti-skid devices use complex structures with multiple moving parts and intricate designs, then the reliability and functionality of the device are improved, but the device complexity and manufacturing costs increase significantly
Solution Approach 1:
The patent combines multiple functions into a single integrated fastening element that attaches to the wheel rim and supports the extension arm. This merging of components reduces the overall number of parts while maintaining the required reliability and anti-skid functionality, directly addressing the contradiction between reliability and device complexity
Solution Approach 2:
The fastening element is designed to serve multiple purposes: attaching to the wheel rim, supporting the extension arm, and providing a mounting point for the anti-skid device. This multi-functionality reduces the need for separate components, thereby reducing device complexity while maintaining reliability
2Adaptability or versatility
If existing anti-skid devices use intricate designs with multiple components, then the functionality and performance are improved, but the assembly complexity and production costs increase
Solution Approach 1:
The patent divides the anti-skid device into modular components: a fastening element, an extension arm, and a holder. This segmentation allows each component to be manufactured independently using simple processes, improving ease of manufacture while maintaining overall functionality through the coordinated assembly of these modular parts
Solution Approach 2:
The patent merges the fastening mechanism and support structure into a single integrated fastening element, reducing the number of parts that need to be manufactured and assembled. This merging simplifies manufacturing processes and reduces production costs while preserving the necessary functionality
3Stability of the object's composition
If the extension arm is rigidly fixed to the fastening element, then the structural stability is improved, but the ability to accommodate wheel diameter variations and positioning adjustments is reduced
Solution Approach 1:
The patent introduces a pivot connection between the extension arm and the holder, replacing a rigid fixed connection with a dynamic articulated joint. This allows the extension arm to rotate and adjust its position, accommodating wheel diameter variations and positioning requirements while maintaining structural stability during operation
4Manufacturing precision
If the distance between the fastening element and coupling element is fixed, then the manufacturing precision is improved, but the adaptability to different wheel sizes and positions is reduced
Solution Approach 1:
The patent replaces the fixed distance constraint with a dynamic pivot connection that allows the extension arm to rotate and adjust its position. This dynamic connection maintains manufacturing precision through controlled articulation while providing adaptability to different wheel sizes and positions through rotational adjustment

AI summary
The device (14) has a fastening element (5) that is fastened to a vehicle wheel (1). The fastening element is connected with a coupling element (15) by an arm (16) that lies in a plane (E) running transverse to a wheel axis (A). The arm has a guide element by which the arm is adjustable into a shifting direction and rotatably guided around a rotational axis relative to the fastening element, where the rotational axis runs parallel to the wheel axis. The arm is formed by sheet metal. The guide element is formed by guidance surfaces of the arm.
