Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail type tool racks with combined end covers face challenges in practical usability due to nonremovable designs or accidental disengagement of elastic buckle blocks, leading to inconvenience in assembly and disassembly.
Innovation Solution
A rail type tool rack design featuring a track with symmetrically arranged tool positioning seats, combined end covers with side claws and an end limit block, and a bump for secure positioning in X, Y, and Z directions, allowing for easy assembly and firm attachment without accidental disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a release press button is provided on the end cover for disengagement, then the end cover can be removed, but the button is located in a region easily pressed by accident, causing unintended disengagement
Solution Approach 1:
The release function is extracted from the end cover itself and transferred to a separate operating mechanism. The user presses the lateral side wall of the track to activate the release, rather than pressing a button on the end cover. This separates the release function from the grip area, eliminating accidental activation while maintaining ease of disassembly.
Solution Approach 2:
The lateral side wall of the track acts as an intermediary element for the release operation. Instead of directly pressing a button on the end cover, the user presses the track's lateral wall, which then transmits the force through the elastic buckle block to release the end cover. This intermediary mechanism prevents accidental activation while preserving user-friendly operation.
2Reliability
If the end cover is fixed with adhesives, then the end cover is securely attached, but it becomes nonremovable, causing inconvenience for future adjustments
Solution Approach 1:
The connection mechanism transitions from a static adhesive bond to a dynamic mechanical connection using an elastic buckle block. The elastic buckle block can be in a locked state for secure attachment or a released state for easy removal. The elasticity of the buckle block allows it to deform during assembly and disassembly, providing both strong attachment when engaged and easy release when activated.
3Device complexity
If the end cover is designed without a release mechanism, then the structure is simpler, but the end cover cannot be removed for future adjustments
Solution Approach 1:
The elastic buckle block provides self-locking functionality, automatically securing the end cover to the track when assembled without requiring additional fastening operations. The elastic deformation of the buckle block creates a self-retaining mechanism that holds the end cover firmly in place while still allowing for easy release when needed, achieving both simplicity and adjustability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides a stable and convenient assembly process with reduced risk of accidental disengagement, ensuring the combined end cover remains securely attached, enhancing user experience and practicality.
Implementation Method 1
uses an elastic buckle block, the elastic buckle block is embedded in a slot opening in the seat surface of railroad shoe when the combined end cover is in combined state
Implementation Method 2
The bump is a block protruding downwards in the position between two side claws from the abutting surface, and the bump is embedded in the corresponding through hole of the intermediate plate for the track
Implementation Method 3
The two side claws are two elastic undercuts protruding downwards near the two lateral sides from the abutting surface, and the two side claws grip the outer side of the corresponding side wall edge of track respectively

AI summary
Disclosed is a tool rack having a track, at least one tool positioning seat and two combined end covers. The track has an intermediate plate, two lateral grooves and two ends. Each lateral groove forms two side wall edges and one side opening, and the intermediate plate is respectively provided with a through hole at a position adjacent to each end. Each combined end cover includes a main body, one end limit block, two side claws and a bump. The main body has two lateral sides and one end side, and an abutting surface used for abutting against an outer wall surface of one side wall edge of the track. The end limit block abuts on the end of the track. The two side claws are respectively gripped and positioned outside the side wall edge of the track, and the bump is embedded in the through hole.
