Solution Overview

Problem

Existing solutions for tool bit management, such as tool caddies and holders, fail to provide efficient retention and easy release of tool bits and small magnetically susceptible hardware items, especially in a vertical orientation, leading to loss and misplacement during use.

Innovation Solution

A magnetic tool bit wallet with a pliable fabric body that can be folded, featuring a magnetic support portion, a bit retainer portion with blocks or channels for tool bits, and a closeable pocket, utilizing alternating polarity magnet assemblies for secure retention and easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional tool caddies and holders are used to store tool bits, then tool bits can be retained, but they are difficult to release quickly and easily during use

Engineering Contradiction:

Improveease of tool bit releaseVSAvoidsecure retention of tool bits

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces traditional mechanical retention systems (elastic bands, hooks, clips) with a magnetic field-based retention system. The magnetic tool holder uses one or more magnets to retain tool bits, eliminating the need for mechanical clamping or binding mechanisms. This substitution enables tool bits to be retained securely through magnetic attraction while allowing for quick and easy release by simply moving the tool bit away from the magnetic field, directly resolving the contradiction between secure retention and ease of release.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the retention mechanism from mechanical force to magnetic force, fundamentally altering the physical parameter used for retention. By using magnetic field strength as the retention parameter instead of mechanical clamp force, the system achieves both strong retention (when tool bits are within the magnetic field) and easy release (when tool bits are moved out of the magnetic field), resolving the contradiction between secure retention and operational ease.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If tool bits are set aside when not in use, then they remain available, but they are subject to loss or misplacement

Engineering Contradiction:

Improveavailability of tool bitsVSAvoidprevention of loss

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The magnetic tool holder provides self-service retention by automatically holding tool bits through magnetic attraction without requiring active user intervention. When tool bits are placed near the holder, they are automatically retained by the magnetic field, eliminating the need for separate storage containers or active management. This ensures tool bits remain readily available while preventing loss through automatic magnetic retention.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If multiple tool bits are carried to the work site, then different functions are available, but tracking and selecting the desired bit becomes time-consuming

Engineering Contradiction:

Improvevariety of tool bit functionsVSAvoidtime to identify and select tool bit

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The magnetic tool holder serves multiple functions: it retains various types of tool bits (drill bits, screwdriver bits, etc.), provides organized storage, enables quick selection, and prevents loss. By consolidating these functions into a single magnetic-based system, the holder supports tool bit versatility while reducing the time needed to identify and select the desired bit, as all bits are readily accessible and visible in one location.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A magnet tool bit wallet includes a fabric body formed from first and second overlying panels, and having a magnetic support portion, a bit retainer portion, and a closeable pocket portion. The magnetic support portion encloses a pair of elongate magnet assemblies between the panels, each magnet assembly including a row of disc magnets disposed between a pair of ferromagnetic strips. The rows of disc magnets have opposite polarity to adjacent magnets, and opposite polarity to corresponding magnets in the other magnet assembly. The bit retainer portion includes at least one block configured to retain tool bits. In a folded configuration the magnet assemblies overlie each other, and a flap on the magnetic portion overlies the pocket portion to retain the wallet in the folded configuration.
