Wrench Handle Driver Storage Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ratchet wrenches lack a structure for storing different drivers, requiring an additional tool box and hindering immediate access, and their manufacturing process is costly due to integral handle and wrench body formation.
Innovation Solution
A wrench design with a movable cover on the handle that contains switchable drivers, allowing for portable storage and separate manufacturing of components to reduce costs and improve accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional ratchet wrench is designed without driver storage structure, then the structure is simple and manufacturing cost is low, but additional tool box is needed and driver access is inconvenient
Solution Approach 1:
The patent merges the driver storage function with the wrench handle by forming a containing space within the handle structure. This integration eliminates the need for separate tool boxes while maintaining structural simplicity, as the storage function is embedded within an existing component rather than adding a completely separate system.
Solution Approach 2:
The wrench handle is designed to serve multiple functions: it provides the structural handle for operation, contains the driver storage space, and incorporates the movable cover mechanism. This multi-functionality reduces the need for additional separate components, resolving the contradiction between operational convenience and structural complexity.
2Reliability
If handle and wrench body are combined by injection molding, then the structure is integrated and reliable, but manufacturing cost remains high and product competitiveness is weakened
Solution Approach 1:
The patent segments the wrench into distinct components: operating section, connecting section, and handle, which are manufactured separately and then assembled. This segmentation allows each component to be optimized for its specific function and manufactured using appropriate processes, reducing overall manufacturing complexity and cost while maintaining structural integrity through quality assembly.
Solution Approach 2:
The patent employs a nested structure where the containing space for driver storage is integrated within the handle, and the movable cover is nested within the handle structure. This nesting approach allows for compact design and efficient use of material while enabling separate manufacturing of components that are then assembled together, balancing structural integrity with manufacturing flexibility.
3Adaptability or versatility
If driver storage space is added to handle, then driver portability is improved, but the handle structure becomes more complex
Solution Approach 1:
The storage space is merged with the handle structure itself rather than being a separate attachment. The containing space is formed as an integral part of the handle, and the movable cover is integrated into the same structure, which minimizes additional complexity while providing versatile driver storage capability.
Solution Approach 2:
The patent introduces a movable cover that can dynamically open and close to access the driver storage space. This dynamic element provides versatility and ease of access while the cover itself is designed as a simple, movable component that integrates with the handle structure, minimizing the increase in overall structural complexity.

AI summary
A wrench with driver in storage includes an operating section having one end thereof provided with a head for movably receiving a driver and the other end thereof provided with a combining part; a connecting section removably combined to the combining part; a handle having a containing space for storing the driver mounted around the connecting section with an end part of the handle mounted around the combining part; and a movable cover, disposed on the handle for sealing the containing space. The driver is stored in the handle of the wrench, facilitating the convenience of usage.
