Modular Tool Box With Sliding Restriction Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool box assemblies face issues with restricted movement and detachment of insertion plates due to connectors, limited locking positions, and difficulty in smooth detachment of the engaging portion from the room, leading to inefficient stacking and handling.
Innovation Solution
The tool box structure incorporates a first and second case with restriction units that allow for modular locking and unlocking of the limit portion, enabling smooth detachment and increased locking positions through the use of first and second restriction units and receiving grooves, allowing for flexible assembly and stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If connectors are snapped onto blocks to stack tool boxes, then stacking stability is improved, but insertion plates are restricted and cannot be detached from notches
Solution Approach 1:
The patent extracts the restriction function from the connectors by introducing separate restriction blocks that can be independently controlled. The connectors focus on stacking stability while the restriction blocks manage the insertion plate detachment, separating these two functions to resolve the contradiction.
Solution Approach 2:
The restriction blocks act as intermediary elements between the connectors and insertion plates. They mediate the interaction by providing a controlled restriction mechanism that allows insertion plates to be detached when needed while maintaining stacking stability during normal operation.
2Device complexity
If connectors only slide leftward or rightward, then connector structure is simple, but locking positions are limited to only three positions
Solution Approach 1:
The patent segments the locking mechanism into multiple independent components: connectors for basic stacking and restriction blocks for additional locking positions. This segmentation allows the system to achieve multiple locking positions (more than three) without significantly increasing the complexity of each individual component.
Solution Approach 2:
The restriction blocks introduce dynamic adjustability to the stacking system. They can be moved along the connectors to provide multiple locking positions, transforming a static three-position system into a more versatile dynamic system with continuous or near-continuous position adjustment capability.
3Device complexity
If hook and inclined face are located at the same side, then structure is compact, but engaging portion cannot be detached from room smoothly
Solution Approach 1:
The patent applies the inversion principle by positioning the hook and inclined face on opposite sides rather than the same side. This spatial inversion resolves the detachment problem by allowing the engaging portion to be released smoothly from the room, while the overall structure remains compact through optimized component arrangement.

AI summary
A tool box structure includes multiple tool boxes. Each of the tool boxes includes a first case, a second case, a first restriction unit, and a second restriction unit. The first case is provided with a receiving space, multiple first mounting portions, a first locking portion, a first inclined face, two second mounting portions, and a limit portion. The second case is provided with multiple third mounting portions, a second locking portion, a second inclined face, two fourth mounting portions, a first receiving groove, a second receiving groove, and a third receiving groove. The first restriction unit is mounted in the first receiving groove and moved in the first receiving groove to restrict or release the limit portion. The second restriction unit is mounted in the second receiving groove. The second restriction unit is assembled with the first restriction unit.
