Solution Overview

Problem

Existing tool storage devices face challenges in securely mounting to walls with varying sizes and shapes, especially those with protruding lips, and often fail to remain stable during transportation and vibrational movements.

Innovation Solution

An adjustable mounting mechanism with a U-shaped or L-shaped bar and shaft collars that can accommodate different wall thicknesses and lips, featuring a locking mechanism to ensure secure attachment and allow for temporary removal and reattachment of the tool tray.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed mounting mechanism is used, then the structure is simple, but it cannot accommodate walls with varying sizes and shapes

Engineering Contradiction:
Improveadaptability to different wall dimensionsVSAvoidmounting mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting mechanism incorporates adjustable components including a shaft collar that can be rotated along the mounting bar to change the distance between the tool tray and the wall. This dynamic adjustment capability allows the same mounting mechanism to adapt to walls of varying thicknesses and configurations, resolving the contradiction between adaptability and structural simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting mechanism is divided into separate functional components: a mounting bar, shaft collars, and locking mechanisms. This segmentation allows each component to be independently adjusted and positioned, enabling the system to accommodate different wall dimensions while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a secure mounting mechanism is used, then the tool tray remains stable during transport, but it becomes difficult to remove and reattach

Engineering Contradiction:
Improvemounting stability during transportVSAvoidease of removal and reattachment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The shaft collar locking mechanism is designed to be self-securing through friction and geometric interlocking. Once the mounting bar is inserted through the shaft collar and the locking feature engages, the mechanism automatically secures itself without requiring additional fasteners or complex locking procedures, thereby maintaining both stability and ease of operation.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the tool tray is fixed to the wall, then it provides stable support, but it cannot be temporarily removed for accessibility

Engineering Contradiction:
Improvetool tray stabilityVSAvoidtemporary removal and reattachment capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The mounting mechanism transitions from a static fixed connection to a dynamic adjustable connection. The shaft collar and mounting bar assembly allows the tool tray to be securely mounted when needed, yet easily detached and repositioned, providing both stability and operational flexibility.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If a universal mounting system is designed, then it can accommodate various wall types, but the manufacturing complexity increases

Engineering Contradiction:
Improveuniversal compatibility with different wallsVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The mounting mechanism is designed as a universal system where the mounting bar and shaft collar combination can accommodate various wall thicknesses and configurations. This multi-functional design achieves universal compatibility through standardized components that can be adjusted rather than through multiple specialized mounting solutions.

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