Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical switches are used for waterproofing, then tactile feedback is provided, but the design becomes complex and waterproofing is difficult to achieve
Solution Approach 1:
The patent replaces traditional mechanical switch components with magnetic fields and hall sensors. The magnetic field interacts with the hall sensor to detect switch state changes without requiring physical contact or mechanical movement, thereby achieving waterproofing while eliminating complex mechanical structures. This substitution of mechanical system with magnetic sensing system directly resolves the contradiction between waterproofing reliability and design complexity.
2Ease of manufacture
If magnetic locks use simple magnet arrangements, then manufacturing is simple, but tactile and acoustic feedback is insufficient
Solution Approach 1:
The patent introduces terrain features with varying local properties (height, roughness, material) along the magnet's movement path. These localized variations create different interaction forces and acoustic signatures at specific positions, providing rich tactile and acoustic feedback without changing the overall simple magnetic lock structure. The local quality principle allows the system to maintain manufacturing simplicity while enhancing feedback information.
Solution Approach 2:
The patent utilizes mechanical vibrations generated when magnets interact with terrain features. As the magnet moves over varying terrain, it produces characteristic vibrations and sounds that provide acoustic feedback. This vibration-based feedback mechanism enhances the information quality without adding complex electronic components, maintaining ease of manufacture while improving tactile and acoustic feedback.
3Ease of manufacture
If fidget toys use simple magnetic components, then manufacturing cost is low, but haptic and acoustic feedback is insufficient
Solution Approach 1:
The patent employs spherical magnets that roll over curved terrain features instead of sliding on flat surfaces. The spherical shape combined with curved terrain creates natural rolling motion and varying contact points, generating rich haptic feedback. This geometric approach enhances sensory feedback quality while using only simple spherical magnets and molded terrain features, maintaining low manufacturing cost.
Solution Approach 2:
The patent generates acoustic and haptic feedback through mechanical vibrations produced when spherical magnets interact with varying terrain. The rolling motion over bumps, valleys, and ridges creates characteristic vibrations and sounds that provide sensory feedback. This vibration-based mechanism achieves enhanced feedback quality without requiring expensive components, maintaining ease of manufacture.
4Ease of manufacture
If tabletop games use smooth plain surfaces, then manufacturing is simple, but player engagement and sensory feedback are reduced
Solution Approach 1:
The patent replaces smooth plain surfaces with three-dimensional terrain featuring curves, bumps, and valleys. The curved terrain interacts with spherical game pieces to create natural rolling motion and varying contact forces, providing tactile feedback that enhances player engagement. The terrain can be molded directly into the game board, maintaining manufacturing simplicity while dramatically improving sensory feedback.
Solution Approach 2:
The patent generates tactile and acoustic feedback through mechanical vibrations as game pieces move over varying terrain. The vibrations produced when pieces roll over different terrain features provide sensory engagement without requiring electronic components. This maintains manufacturing simplicity while significantly enhancing player sensory engagement and game experience.

Function Achieved in This Case
Offers novel sensory experiences, low-cost manufacturing, and realistic feedback in fidget toys, switches, and games, with potential applications in underwater use and automated systems.
Implementation Method 1
a control magnet is used to drag an escorted magnet over a rugged surface... the strength of the magnetic coupling between them, and can be felt as tactile or haptic feedback
Implementation Method 2
Features of the rugged terrain causes the escorted item to move closer to or farther from the control peg, as the escorted item is dragged across the terrain... Both height and planar interactions may produce various types of acoustic feedback

AI summary
A fidgetable device that relays haptic feedback via magnetic coupling to hands and fingers, when an operator uses an outside magnet to drag an inside magnet over a rugged interior surface. This haptic experience is akin to walking a pet on a retractable leash. Thus the designation fidget walker. Said haptic device, with its acoustic side effects, is also widely applicable in a variety of fields including percussion instruments, underwater switches, magnetic locks, tabletop games, and even automated machineries.
