Retractable Toolbox Connector for Obstruction-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices for tools and toolboxes interfere with large or irregular items when placed on storage surfaces, necessitating a solution that allows for a simple and convenient mounting structure without obstruction.
Innovation Solution
A connecting device with a base and a connecting assembly that can switch between a connection state and a hidden state, allowing the connector to be at a mating position or a hidden position relative to the base, facilitating easy mounting and dismounting of items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connecting device is mounted on the tool or toolbox to enable attachment of additional items, then the versatility and functionality of the tool system is improved, but the connecting device may interfere with large or irregular items when they are placed on the storage surface
Solution Approach 1:
The connecting assembly is designed to be movable relative to the base, capable of switching between a connection state (protruding outward to engage with to-be-mounted parts) and a hidden state (retracted into the accommodation cavity). This dynamic configuration allows the connecting device to adapt its position based on operational needs, eliminating interference with items placed on the storage surface while maintaining attachment functionality when required
Solution Approach 2:
The connecting assembly is nested within an accommodation cavity formed in the base when in the hidden state. The connector can be stored inside the base structure, allowing the connecting device to occupy minimal space and not protrude outward to interfere with item placement. When needed, the connecting assembly can be deployed from this nested position
2Adaptability or versatility
If the connecting assembly is always in the connection state to ensure mounting capability, then the versatility is improved, but the connecting assembly may be damaged by items placed on the storage surface
Solution Approach 1:
The connecting assembly transitions from a static to a dynamic configuration, being movable between the connection state and hidden state. When not in use, it retracts into the accommodation cavity, protecting the connector from damage by items placed on the storage surface. When needed, it can be deployed to the connection state to perform mounting operations
Solution Approach 2:
The accommodation cavity provides preliminary protection for the connecting assembly by receiving and shielding the connector when it is not in use. This pre-protective measure prevents damage before it can occur, extending the service life of the connecting assembly
3Ease of manufacture
If the connecting device has a simple structure to ease manufacture, then the ease of manufacture is improved, but the ability to switch between connection and hidden states may be compromised
Solution Approach 1:
The connecting assembly incorporates a movable connection mechanism that allows it to switch between states. The connecting base can be pivotally connected to the base, or the connecting assembly can slide within the accommodation cavity, providing state switching capability through relatively simple mechanical movements rather than complex mechanisms
Solution Approach 2:
The connecting device is divided into separate components: a base with an accommodation cavity and a connecting assembly that can move relative to the base. This segmentation allows each component to be manufactured independently with simpler structures, while the overall system achieves the required state switching capability through the interaction of these simplified parts

AI summary
Provided is a cart. A cart includes a connecting device formed on or connected to the cart. The connecting device is configured to mount a to-be-mounted part onto the cart. The connecting device includes a base formed on or connected to the cart, where the base is formed with an accommodation cavity; and a connecting assembly connected to the base, where the connecting assembly is configured to be connected to the to-be-mounted part. The connecting assembly includes a connector mating with the to-be-mounted part to connect to the to-be-mounted part. The connecting assembly has at least a connection state and a hidden state relative to the base. When the connecting assembly is in the connection state, the connector is at a mating position so that the connector is capable of mating with the to-be-mounted part. When the connecting assembly is in the hidden state, the connector is at a hidden position so that the connector is separated from the mating position.
