Tool Box Storage Member Pivoting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool boxes do not allow screwdriver heads or sockets to be pivoted for exhibition purposes, limiting their functionality and ease of recognition and retrieval.
Innovation Solution
A tool box design featuring two pivoted halves with positioning units and storage members that can pivot and be fixed in various angles, including vertical, inclined, and horizontal positions, allowing for improved tool storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If storage members are fixed in conventional tool boxes, then tools can be stored for easy recognition and pickup, but the tools cannot be pivoted for exhibition purposes
Solution Approach 1:
The storage member is designed with pivoting capability through arc-shaped guide grooves that allow the storage member to rotate between vertical, inclined, and horizontal positions. The positioning units can move along these curved paths to lock the storage member in different orientations, transforming a static storage system into a dynamic one that adapts to various display and storage needs.
Solution Approach 2:
The positioning mechanism is divided into discrete positioning units distributed along the arc-shaped guide grooves. Each positioning unit can independently engage with the guide groove at different locations, allowing the storage member to be segmented into multiple selectable positions rather than requiring a continuous complex mechanism.
2Adaptability or versatility
If multiple positioning units are added to enable pivoting, then tool exhibition capability is improved, but the structural complexity of the tool box increases
Solution Approach 1:
The arc-shaped guide grooves serve multiple functions: they guide the pivoting motion of the storage member, define the available rotation paths, and provide engagement surfaces for the positioning units. This single structural element accomplishes what would otherwise require separate complex mechanisms for each function.
Solution Approach 2:
The use of arc-shaped guide grooves instead of straight linear guides enables smooth rotational movement while maintaining compact space utilization. The curved geometry naturally constrains the motion to a circular path, simplifying the positioning mechanism compared to using multiple linear actuators or complex joint systems.

AI summary
A tool box includes two pivoted halves and a chamber with a bottom and two opposite walls. A plurality of positioning units formed in the walls each include a positioning cavity located in one direction, a first guide groove located farther from the bottom than the positioning cavity, a first pivot cavity at one end of the first guide groove and located in the one direction, a second pivot cavity formed at another end of the first guide groove and located in another direction, a second guide groove and located between the first pivot and positioning cavities, a third pivot cavity formed at one end of the second guide groove, located in the two directions and disposed between the first pivot and positioning cavities, and a fourth pivot cavity formed at another end of the second guide groove and located between the second pivot cavity and the bottom.
