Pivotable Tool Holder for Secure Bit Retention and Dual-Side Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable toolboxes fail to securely retain bits and spanners, leading to accidental drops when the cover is opened, as bits can fall from sockets and spanners are exposed and prone to falling off.
Innovation Solution
A portable toolbox design featuring a pivotable holder within a frame, allowing the holder to be positioned either retreated or extended, with the holder's base and protrusions ensuring secure retention of bits and spanners, and clips to prevent spanner escape, while allowing access from both sides when extended.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is opened to access bits, then the bits can be taken out, but the bits may accidentally fall from the sockets
Solution Approach 1:
The patent applies preliminary anti-action by designing the holder with a structure that proactively prevents bit dropout before it can occur. The holder includes a base with protrusions that extend into the sockets from below, creating a physical barrier that stops bits from falling out even when the cover is opened. This preventive structure is built in advance and continuously active, counteracting the potential harmful effect of bit dropout.
2Ease of operation
If the spanner is held exposed outside the holder, then it is easily accessible, but it contacts objects and drops because there is no cover to protect it
Solution Approach 1:
The patent applies segmentation by dividing the holder into distinct functional zones: an exposed region for the spanner that remains accessible, and a protected region with a cover for the bits. The spanner is held in a dedicated position outside the main holder body, allowing easy access while the bit sockets are enclosed when the cover is closed. This spatial segmentation allows each component to be accessed or protected as needed.
3Ease of operation
If the holder is fixed in position, then the structure is simple, but the bits and spanner cannot be accessed from both sides
Solution Approach 1:
The patent applies dynamics by making the holder pivotable relative to the frame. The holder can rotate between a first position where bits are accessible from one side and a second position where spanner is accessible from the opposite side. This dynamic movement allows flexible access to different components based on which side the user is approaching from, while the pivot mechanism maintains structural integrity.

AI summary
A portable toolbox is disclosed. The portable toolbox includes a frame and a holder. The holder can hold a plurality of bits. The holder is put in the frame so that the holder can be pivoted between a retreated position and an extended position relative to the frame. In the retreated position, the bits are kept in the holder in cooperation with the frame. In the extended position, the bits can be put onto and taken from the holder from two opposite sides of the frame.
