Solution Overview

Problem

Conventional tool suspension members have limited capacity for tool storage, are cumbersome in size, and require the cover to be removed for tool retrieval, making them inconvenient for use.

Innovation Solution

A tool suspension device featuring a suspension member with pivot structures that allow two receiving members to pivot and stack together, minimizing size while maximizing tool capacity and facilitating easy tool access by pivoting apart for retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional suspension members use a closed cover design with partition plates, then tool storage capacity is limited and size is large, but tool security is maintained

Engineering Contradiction:
Improvetool storage capacityVSAvoidsuspension member size
Core Design Contradiction:
Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The first and second receiving members are designed to be nested or piled together when not in use, with the second receiving member positioned inside or alongside the first receiving member. This nesting arrangement minimizes the overall volume of the suspension device while maintaining the capacity to store multiple tools across both receiving members.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The receiving members are made movable relative to each other through pivot connections, allowing them to transition between a compact piled-together state for storage and an expanded apart state for tool access. This dynamic configuration enables the device to adapt its volume based on operational needs.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If conventional suspension members use a closed cover design, then tool security is maintained, but tool retrieval requires cover removal making operation inconvenient

Engineering Contradiction:
Improvetool retrieval convenienceVSAvoidcover removal mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The receiving members are connected via pivot structures that allow them to rotate or pivot open, replacing the static cover removal mechanism with a dynamic pivoting action. This enables users to access tools by simply pivoting the receiving member apart from the suspension member, eliminating the need to remove covers entirely.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The suspension device is segmented into the suspension member and separate receiving members that can move independently. This segmentation allows the receiving members to be pivoted apart for tool access while maintaining the overall structural integrity of the suspension device.

Inventive Principle:
Principle #1Segmentation

3Quantity of substance

If multiple receiving members are added to increase tool capacity, then storage capacity improves, but device size and complexity increase

Engineering Contradiction:
Improvetool storage capacityVSAvoidnumber of components
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The first and second receiving members are designed to nest within or alongside each other, allowing multiple tool storage compartments to occupy a compact spatial footprint. This nesting reduces the overall device complexity by minimizing the space and structural support needed for multiple receiving members.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The pivot structures serve dual functions: they enable the receiving members to move for tool access while also serving as connection points that secure the receiving members to the suspension member. This merging of movement and connection functions reduces the need for separate fastening mechanisms, thereby reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A tool suspension device includes a suspension member, a first and a second receiving members. The suspension member is protrudedly formed with a first and a second pivot structures at two ends. The suspension member has a suspension portion for suspension. The first and the second receiving members are pivotably connected with the first and the second pivot structures respectively. Thus, the first receiving member and the second receiving member are able to be piled together for storing. Also, the first and the second receiving members are able to pivot to be unfolded for available of tools for a user.
