Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving tools lack efficient storage solutions for engagement bits, such as sockets and screwdriver bits, which often result in inconvenience and difficulty in accessing the desired bit during use.
Innovation Solution
The driving tool incorporates a handle with a cavity and an end cap that retains engagement bits, and a shaft with multiple steps to accommodate various sized sockets, allowing for convenient storage and easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If driving tools include storage for engagement bits, then convenience of accessing bits is improved, but device complexity increases
Solution Approach 1:
The patent implements nesting by placing engagement bits inside a cavity within the handle body, and further nesting the end cap inside the cavity when closed. This allows the storage mechanism to be integrated within the existing handle structure rather than adding external components, thereby improving bit accessibility while minimizing increases in overall device complexity.
Solution Approach 2:
The patent merges the bit storage function with the existing handle structure by incorporating a cavity into the handle body and using the end cap as both a closure and a retention mechanism. This combining of storage functionality with the handle itself avoids adding separate standalone storage devices, thus improving convenience while controlling structural complexity.
2Adaptability or versatility
If shaft includes multiple steps for different sized sockets, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies local quality by creating multiple steps at specific locations along the shaft to accommodate different socket sizes. Each step is positioned and dimensioned to match specific socket dimensions, allowing the shaft to interface correctly with various socket types while maintaining a relatively simple overall cylindrical form that is easy to manufacture.
Solution Approach 2:
The shaft is segmented into multiple stepped sections along its length, with each step providing a different diameter interface for various socket sizes. This segmentation allows the single shaft component to serve multiple functions with different tool attachments while maintaining a straightforward manufacturing process using conventional turning or machining operations.

AI summary
Various embodiments of a driving tool with bit storage are provided. In a specific embodiment, the driving tool includes a handle, a shaft, and a socket. The shaft is centered on and extends along a longitudinal axis. The shaft includes a flange extending away from an external surface of the shaft. The flange includes a first step extending circumferentially around the longitudinal axis, and the first step defines a first radius. The flange further includes a second step extending circumferentially around the longitudinal axis, and the second step defines a second radius different from the first radius. The socket includes a first end configured to engaged with the first step such that the first step defines a first effective depth of the socket.
