Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact-type interference method is used to generate tactile feel, then tactile feedback is achieved, but wear occurs on the wheel module over time
Solution Approach 1:
The patent replaces the contact-type mechanical interference method with a magnetic field-based non-contact method. The first magnetic module generates a magnetic field that interacts with the metal ratchet to produce tactile feedback, eliminating physical contact between the magnetic module components and the ratchet, thereby preventing wear while maintaining tactile feedback functionality.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the control mechanism and the metal ratchet. The magnetic field serves as a non-contact mediator that can apply force to the ratchet teeth to generate tactile feedback without requiring direct physical contact, thus solving the wear problem while preserving the tactile feedback function.
2Reliability
If contact-type interference method is used, then tactile feel is generated, but rotating mode cannot be switched immediately
Solution Approach 1:
The patent replaces the mechanical contact-based mode switching mechanism with a magnetic field-based system. The magnetic field can be rapidly adjusted and switched without the mechanical delays inherent in contact-type systems, enabling immediate mode switching while maintaining tactile feedback through magnetic interaction with the metal ratchet.
Solution Approach 2:
The patent employs a dynamic magnetic field control system that can rapidly adjust the strength and configuration of the magnetic field to switch between different rotating modes. This dynamic control allows for immediate mode transitions without the mechanical inertia and contact delays associated with traditional mechanical switching mechanisms.
3Loss of substance
If non-contact magnetic interaction is used, then wear is reduced, but tactile feedback mechanism must be redesigned
Solution Approach 1:
The patent replaces complex mechanical contact structures with a magnetic field-based system. The first magnetic module uses magnetic fields to interact with the metal ratchet, eliminating the need for complex mechanical contact structures and reducing wear. The magnetic interaction provides a simpler, more durable mechanism for generating tactile feedback.
Solution Approach 2:
The patent changes the fundamental interaction parameter from mechanical contact force to magnetic field force. By utilizing magnetic field strength and distribution as the control parameter instead of mechanical contact pressure, the system achieves wear-free operation while maintaining tactile feedback. The magnetic module structure is optimized to generate appropriate magnetic field patterns for tactile feedback generation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid switching between tactile and non-tactile modes, reducing wear and enhancing the durability of the wheel module while maintaining tactile feedback, outperforming conventional contact-type interference methods.
Implementation Method 1
The first magnetic module includes a first magnetic element, a first magnetic conductor and a second magnetic conductor. The first magnetic element is arranged between the first magnetic conductor and the second magnetic conductor.
Implementation Method 2
If the second magnetic element is introduced into the magnet accommodating space and like poles of the second magnetic element and the first magnetic element face each other, magnetic attractive forces generated at the first end of the first magnetic conductor and the first end of the second magnetic conductor attract the metal ratchet.

AI summary
A wheel control mechanism includes a support base, a wheel module, a first magnetic module and a second magnetic module. The wheel module, the first magnetic module and the second magnetic module are installed on the support base. The first magnetic module generates a magnetic attractive force to attract a metal ratchet of the wheel module. By adjusting the position of the second magnetic module relative to the first magnetic module, the strength of the magnetic attractive force is changed. Consequently, the rotation of the wheel module results in a tactile feel or does not result in the tactile feel.
