Magnetic Rotating Tool Rack for Fast Vehicle Tool Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency vehicle tool holders with mechanical locks require excessive time and risk over-rotation when accessing tools, as releasing the lock and rotating the turntable adds seconds to retrieval and can place tools out of reach.
Innovation Solution
A rotatable vehicle tool rack with circumferentially-spaced base and turntable magnets that maintain distinct stable positions through magnetic interaction, reducing the distance between magnets as tool weight increases, allowing quick and precise access to tools without user-applied torque above a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical lock is used to inhibit rotation of the turntable, then the turntable can be securely locked during vehicle motion, but releasing the lock adds time to tool access and risks over-rotation
Solution Approach 1:
The patent replaces the mechanical lock system with a magnetic field-based positioning system. Magnets are embedded in both the base and turntable to create magnetic attraction zones that automatically hold the turntable at specific rotational positions. This eliminates the need for manual lock release and prevents over-rotation, as the magnetic fields provide continuous positional guidance and holding force without requiring user intervention.
Solution Approach 2:
The magnetic positioning system provides self-aligning and self-holding functionality. The turntable automatically aligns with the magnetic attraction zones and maintains its position without external control. The system serves itself by using the interaction between base magnets and turntable magnets to create stable equilibrium positions, eliminating the need for manual locking or unlocking operations.
2Stability of the object's composition
If a mechanical lock is used to secure the turntable, then the turntable remains stable during vehicle motion, but the locking mechanism increases device complexity
Solution Approach 1:
The patent replaces complex mechanical locking components (latches, springs, levers) with a simpler magnetic field system. The magnetic attraction between base magnets and turntable magnets provides sufficient holding force to stabilize the turntable during vehicle motion, eliminating the need for intricate mechanical locking mechanisms while maintaining stability.
Solution Approach 2:
The patent changes the fundamental parameter of interaction from mechanical contact forces to magnetic field forces. By using magnetic field strength and distribution as the controlling parameter, the system achieves stable turntable positioning with simpler components. The magnetic fields create potential energy wells that naturally stabilize the turntable at specific positions without requiring mechanical constraints.
3Productivity
If the turntable can rotate freely for quick access, then tool retrieval is faster, but over-rotation can occur placing tools out of reach
Solution Approach 1:
The patent uses magnetic field guidance to replace mechanical stopping mechanisms. As the turntable rotates, the magnetic attraction zones provide continuous feedback and holding force at specific positions, guiding the user to the correct tool location without requiring abrupt stops or mechanical barriers that could cause over-rotation.
Solution Approach 2:
The magnetic positioning system provides continuous positional feedback through the interaction between base magnets and turntable magnets. The magnetic attraction zones create distinct stable equilibrium positions that give tactile and visual feedback to the user, indicating when the correct tool position is reached. This feedback mechanism prevents over-rotation by providing natural stopping points.
