Tool Assembly with Ratchet Mechanism and Pivotable Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool assemblies have limited expandability for drive bits, requiring complex and inconvenient steps to switch between tools, as the outer and inner sleeves can only accommodate a limited number of bits.
Innovation Solution
The tool assembly features a first part with multiple receiving units and a ratchet mechanism, allowing for easy removal and reconnection of tools, along with pivotable second tool units, enabling more tools to be carried and used without the need for reverse connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple drive bits are stored in nested sleeves, then the number of tools carried is increased, but the structure becomes complex and tool switching becomes inconvenient
Solution Approach 1:
The tool assembly is divided into separate functional modules: a handle with receiving units for storing drive bits, and a separate operation member with a ratchet mechanism. This segmentation eliminates the need for nested sleeves while maintaining the capability to carry multiple bits, thereby reducing structural complexity.
Solution Approach 2:
The invention extracts the drive bits from the nested sleeve structure and places them in dedicated receiving units within the handle. This extraction simplifies the overall structure by removing the complex nested sleeve mechanism while preserving the function of carrying multiple bits for easy access.
2Quantity of substance
If drive bits are stored in nested sleeves, then multiple tools can be carried, but the process of switching between bits becomes time-consuming
Solution Approach 1:
Drive bits are pre-positioned in individual receiving units within the handle, ready for immediate access. This preliminary arrangement eliminates the need to manually navigate nested sleeves or reverse connections, allowing users to quickly select and attach the required bit to the operation member, significantly reducing tool switching time.
3Reliability
If a ratchet mechanism is added for secure engagement, then tool retention is improved, but the device complexity increases
Solution Approach 1:
The ratchet mechanism is integrated into the operation member itself, allowing it to automatically engage and secure the drive bit through its inherent ratchet action. This self-service mechanism provides secure tool retention without requiring additional external locking devices or complex assembly procedures, thereby maintaining simplicity while improving reliability.

AI summary
A tool assembly includes a first part, a second part, an operation member, two second tool units, and two first connection members. The first part has a first space, two first rails, two first engaging portions, two second spaces and two first connection portions. The second part has a head and a receiving portion which is insertion in the first space and includes receiving units for receiving first tools therein. Two second rails are formed on the second part and slidably engaged with the first rails. The operation member is connected to the second part. The two second tool units are pivotably connected to the two first connection portions and located in the two second spaces. The second tool units each have second tools which are pivotable about the first connection portion corresponding thereto. The first tools can be removed from the receiving units and connected to the operation member.
