Pivoting Door Wrench Case for Secure Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrench cases do not efficiently store and transport combination wrenches, as they lack a secure and user-friendly mechanism for easy access and organization of wrenches of varying sizes.
Innovation Solution
A wrench case with a body, post, and pivotally coupled door that allows each wrench to be easily removed and stored, featuring stepped sections on the post for size accommodation, and a double hinge door that pivots 360 degrees, along with elastic latches for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional wrench case design is used, then the structure is simple, but the ease of operation for removing and storing wrenches is poor
Solution Approach 1:
The door is pivotally coupled to the body, allowing it to rotate between a closed position (for secure storage) and an open position (for easy access). This dynamic element enables users to quickly retrieve or store wrenches by simply pivoting the door, dramatically improving ease of operation without requiring complex tools or mechanisms.
Solution Approach 2:
The wrench case is divided into distinct functional segments: a body for storage, a pivotally coupled door for access, posts for securing wrenches, and tabs for organization. This segmentation allows each component to perform its specific function efficiently, making the overall system easier to operate while maintaining reasonable complexity.
2Adaptability or versatility
If wrenches of varying sizes are stored together, then the adaptability is improved, but the organization and retrieval efficiency deteriorates
Solution Approach 1:
The posts are positioned at specific locations within the body, and tabs are spaced apart along the front side to create gaps of varying dimensions. Each gap is locally optimized to accommodate wrenches of specific sizes, allowing the case to adapt to various wrench sizes while maintaining organized separation that enables quick identification and retrieval.
Solution Approach 2:
The design incorporates both horizontal spacing (tabs spaced apart along the front side) and vertical positioning (posts at different locations) to create a two-dimensional organization system. This dimensional approach allows multiple wrench sizes to be stored simultaneously in an organized manner, improving both adaptability and retrieval efficiency.
3Ease of operation
If the door is always open for easy access, then the ease of operation is improved, but the security and protection of wrenches during transport deteriorates
Solution Approach 1:
The pivotally coupled door provides dynamic functionality, allowing it to be open during use for easy access to wrenches, and closed during transport to secure the wrenches inside. This dynamic capability resolves the contradiction by enabling the door to adapt its state based on the operational context.
Solution Approach 2:
The door can be closed and latched before transport, preliminarily securing the wrenches in place within the body. This preliminary action ensures that during transport, the wrenches are protected and cannot shift or fall out, while still allowing quick access when the door is opened at the destination.
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
Enables secure storage and easy access to wrenches of different sizes, preventing sliding during transport and allowing for efficient organization and retrieval, enhancing user convenience.
Implementation Method 1
The case includes an elastic latch that engages with the door to retain the door in the closed position
Implementation Method 2
The door is pivotally coupled to the body. The door is pivotable relative to the body between a closed position and an open position

AI summary
A wrench case for a set of combination wrenches, where each wrench includes an open end, a closed end, and an elongate handle extending therebetween. The wrench case includes a handle, a post receiving the open end of each wrench, and a body including a front side and a back side. The front side supports the elongate handle of each wrench. The wrench case further includes a plurality of tabs spaced apart along the front side of the body. Between adjacent tabs is a gap that receives each wrench. The wrench case further includes a door pivotally coupled to the body between a closed position, in which the door is coupled adjacent the front side of the body to maintain each wrench against the body, and an open position, in which the door is coupled adjacent the back side of the body.
