Toolbox With Crossed Strips And Notched Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toolboxes lack effective positioning mechanisms for containers, leading to components being dislodged during movement and instability when stacked, causing inconvenience in use and component retrieval.
Innovation Solution
A toolbox design featuring crossed strips on the inner bottom of one shell and notches on the container bottoms for secure positioning, along with indented lids and pegs for enhanced stacking stability, allowing containers to be placed randomly and stacked securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If containers are placed in the toolbox without a positioning mechanism, then the toolbox structure is simple, but the containers move randomly during movement causing components to disperse
Solution Approach 1:
The bottom of the toolbox is segmented into multiple regions by dividing lines, and the container bottom is segmented with notches that align with these dividing lines. This segmentation allows for simple structural design while providing stable positioning of containers in specific locations.
Solution Approach 2:
The notches on the container bottom and the corresponding positioning structures on the toolbox bottom act as intermediary elements that connect and secure the container to the toolbox, preventing random movement while maintaining overall structural simplicity.
2Device complexity
If containers are stacked without stacking design, then the structure is simple, but the stacked containers fall down easily causing inconvenience
Solution Approach 1:
Containers are designed to be stacked one on top of another like nested dolls, with the upper container fitting over the lower container. The notches on the bottom of upper containers align with protrusions or positioning features on the lids of lower containers, creating a stable nested arrangement that prevents falling while adding minimal structural complexity.
Solution Approach 2:
The stacking mechanism utilizes the vertical dimension by creating interlocking features between the bottom of upper containers and the lid of lower containers. The notches and corresponding positioning elements engage in the vertical stacking direction, providing stability through three-dimensional interlocking rather than relying solely on horizontal placement.
3Stability of the object's composition
If containers are positioned using protrusions in vacant areas, then positioning is achieved, but the positioning part can only be placed in specific vacant areas causing inconvenience
Solution Approach 1:
The notches on the container bottom are designed to work universally with the dividing lines and positioning structures distributed across the entire toolbox bottom. This universal design allows containers to be positioned flexibly in multiple locations rather than being restricted to specific vacant areas, enhancing both positioning stability and placement convenience.

AI summary
A toolbox is disclosed, comprising a case having two shells, wherein one of the two shells is formed with several strips which are crossed at right angles, and several containers put in the case and formed with several notches at a bottom edge of a body of the container to engage with the strips of the shell for positioning the container. Therefore, the containers can be put at any position in the toolbox by corresponding the strips which are crossed at right angles at the shell to the notches at the container's bottom, increasing the convenience of the positioning of the containers. Besides, when the containers are stacked with each other, the notches at the outer bottom of the body of the upper container is engaged with pegs on the lid of the lower container for positioning, thereby increasing the stability in the stacked condition.
