Tool Box With Peg Sheet Partition And Rotatable Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool boxes fail to securely store tools of various sizes without displacement during handling and provide adequate visibility when the cover is open, and the manufacturing of uniform peg rows is challenging due to deformation during welding.
Innovation Solution
A tool box design featuring rotatable covers and partition plates with peg sheets that securely hold tools in place, allowing visibility and preventing intermingling, along with a method for forming pegs that ensures uniform spacing and reduces manual labor through angled pegs and latches for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tools are placed in designated channels or compartments, then tools are organized and visible, but tools become displaced and scattered during rough handling or inversion
Solution Approach 1:
The tool box interior is divided into multiple compartments with individual lids, creating separate storage zones. Each compartment can be independently accessed while maintaining secure tool placement through the lid closure mechanism that prevents tool displacement during handling.
Solution Approach 2:
The lid closure mechanism applies a preliminary restraining action on tools placed in compartments. When the lid is closed, it creates a physical barrier and securing force that prevents tools from being displaced during subsequent handling or inversion of the tool box.
2Reliability
If individual lids are added to compartments to prevent tool displacement, then tool position stability is improved, but tool visibility and ease of finding appropriate tools deteriorates
Solution Approach 1:
The lids are designed to be rotatable between open and closed positions, creating a dynamic system. When closed, lids secure tools in place; when opened, they provide full visibility and access to tools. This dynamic capability allows the system to switch between securing and accessibility modes as needed.
Solution Approach 2:
The lids are pre-positioned in a closed state to secure tools, but can be quickly opened when tool access is needed. The preliminary closed position maintains tool stability while the quick-open capability ensures tools remain visible and accessible when required.
3Reliability
If metal pegs are welded to plates for tool storage, then tools are securely held in position, but uniform spacing and alignment of pegs becomes difficult due to deformation from welding heat
Solution Approach 1:
The welding process is replaced with a cold-forming process where pegs are formed from a flexible sheet material. This substitution eliminates the heat deformation problem inherent in welding while achieving the same tool-securing function through mechanical engagement of the formed pegs with tools.
Solution Approach 2:
The manufacturing method changes from thermal joining (welding) to mechanical forming (cold-forming). This parameter change in the manufacturing process eliminates heat-induced deformation and enables precise control over peg spacing and alignment through the forming process rather than welding.
4Quantity of substance
If numerous storage pegs are added to maximize tool storage capability, then storage capacity is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
Multiple pegs are merged into a single integrated sheet structure that can be formed as one piece. This combining approach allows numerous pegs to be created without increasing manufacturing complexity, as the entire peg array is formed through a single cold-forming process rather than assembling individual pegs.
Solution Approach 2:
The sheet material serves multiple functions: it provides the structural framework for the pegs, acts as the mounting surface, and enables the cold-forming process that creates all pegs simultaneously. This multi-functionality reduces the number of separate components and simplifies manufacturing while maximizing tool storage capacity.

AI summary
A tool box has a bottom portion, a pair of side portions, a back portion, a front portion, and a cover rotatably mounted adjacent the back portion. The cover has a horizontal section and a slanted section sloping downwardly from the horizontal section. A partition plate is positioned in the interior of the tool box and has a peg sheet mounted thereto with a row of pegs extending upwardly from the top of the partition plate. The upper ends of the pegs contact or are in close proximity to the horizontal section of the cover when the cover is in its closed position such that tools disposed on the pegs are secured in position. A pair of compartments are positioned in the interior, one near the bottom of the box and one intermediate the bottom and the top, both having a cover structure disposed thereon with peg sheets for maintaining tools in secured and unsecured positions.
