Solution Overview

Problem

Conventional tool hangers require users to remove and rehang them or add additional hooks to change horizontal positions, which is inconvenient.

Innovation Solution

A tool hanger with a hanging hole featuring positioning grooves that allow engagement with hooks during horizontal movement, enabling stable repositioning without removing or adding hooks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a conventional tool hanger uses two fixed hanging holes for stable wall mounting, then the hanging stability is improved, but the ability to easily change horizontal position deteriorates

Engineering Contradiction:
Improvehanging stabilityVSAvoidease of horizontal repositioning
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The hanging hole is segmented into multiple positioning grooves (first, second, third positioning grooves) arranged horizontally, allowing the hook to engage with different grooves to achieve various horizontal positions while maintaining stable hanging

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hanging hole structure transitions from fixed positions to dynamically adjustable positions through the array of positioning grooves, enabling the tool hanger to be repositioned horizontally by simply moving it along the wall while maintaining engagement with the hook

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If additional hooks are added to the wall to change horizontal position, then the positioning flexibility is improved, but the device complexity and installation difficulty worsen

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The single hook on the wall serves multiple functions by engaging with different positioning grooves, allowing the same hook to support the tool hanger at various horizontal positions without requiring additional hooks or wall modifications

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A tool hanger includes a main body having an upper portion and a lower portion opposite to the upper portion. The upper portion of the main body is provided with a hanging hole having a top wall and a plurality of positioning grooves located on the top wall and for engaging with a hook. The lower portion of the main body is provided with a tool hanging part for hanging at least one tool. As such, when a user horizontally moves the tool hanger, the hook is positionable in any one of the positioning grooves, allowing the tool hanger to be easily horizontally moved and stably positioned.
