Solution Overview

Problem

Existing tool holders often compromise between securely engaging a tool and providing flexibility of motion, with configurations prioritizing retention and security at the expense of user comfort.

Innovation Solution

A tool mount with a locking handle and positioning wheel that allows for a sleever bar to be secured in a fixed position or rotated freely, featuring a retention assembly with ball detents and engagement features to ensure stable attachment and user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the tool holder uses a fixed securement mechanism (such as an angled holder), then tool retention and security are improved, but user comfort and flexibility of motion deteriorate

Engineering Contradiction:

Improvetool retentionVSAvoidflexibility of motion

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The tool holder employs a dynamic locking mechanism that can transition between locked and unlocked states. The locking handle with ball detents and engagement features allows the positioning wheel to be either fixed in place or free to rotate, enabling the system to adapt between secure retention and flexible motion based on operational needs.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the tool holder allows free rotation (such as a leather belt strap with free-rotating pigtail), then flexibility of motion is improved, but tool security and retention deteriorate

Engineering Contradiction:

Improveflexibility of motionVSAvoidtool security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The positioning wheel coupled to the locking handle creates a dynamic system where the tool can freely rotate when unlocked but can be securely fixed when needed. The ball detent mechanism provides automatic engagement at specific positions, ensuring both flexibility and security are achieved through the same mechanism.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If the tool holder uses a fixed position mechanism, then tool stability is improved, but adaptability to different working conditions deteriorates

Engineering Contradiction:

Improvetool stabilityVSAvoidadaptability to working conditions

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The tool holder design incorporates multiple functions within a single mechanism. The positioning wheel with engagement features can accommodate different tool orientations and positions, while the locking handle provides both locked and unlocked modes, making the device adaptable to various working conditions while maintaining stability when needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A tool mount for use with a sleever bar includes a locking handle moveable between a secured position and a locked position. The tool mount further includes a positioning wheel aligned adjacent to the locking handle. The positioning wheel may be configured to engage the locking handle when the locking handle is in the locked position, and rotate freely relative to the locking handle when the locking handle is in the secured position. The tool mount further includes a tool holder coupled to the positioning wheel and configured to receive the sleever bar, wherein the tool holder rotates freely with the positioning wheel when the locking handle is in the secured position.
