Multi-tool Pre-deployment and Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-tools are difficult to open due to compact storage of numerous tool components, making it hard for users to quickly access and choose a specific tool component.
Innovation Solution
A multipurpose tool with a pre-deployment assembly that partially opens and extends tool components at various angles, combined with a handle pivoting and locking mechanism, allowing easy access and secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tool components are compactly stored within the handle bodies, then the tool maintains a compact form factor, but users cannot quickly access and choose specific tool components
Solution Approach 1:
The pre-deployment assembly performs preliminary action by partially opening and positioning tool components at various angles before the user selects a specific tool. This preliminary deployment makes the tool components visible and accessible, allowing users to quickly choose and access the desired tool without having to fully open or search through compactly stored components.
2Volume of moving object
If handles are made pivotable for storage, then the tool can be compactly stored, but accidental movement may occur during use
Solution Approach 1:
The locking mechanism dynamically adapts to the handle's position. When the handle is in the extended working position, the locking mechanism engages to prevent movement. When the handle needs to be repositioned for storage, the locking mechanism disengages, allowing the handle to pivot to a compact storage position. This dynamic behavior provides both secure operation and compact storage capability.
3Adaptability or versatility
If numerous tool components are stored within handle bodies, then the tool becomes multi-functional, but the complexity of opening and accessing components increases
Solution Approach 1:
The tool components are segmented and arranged at different angles and positions within the handle bodies. The pre-deployment assembly segments the opening action by partially deploying each tool component independently to a specific angle, rather than requiring all components to be opened simultaneously or through a complex single mechanism. This segmentation simplifies the overall opening process while maintaining multi-functionality.

AI summary
A hand tool, such as a multi-tool including pivotable handles is shown. The multi-tool includes a first and second handle, a first and second jaw portion, coupled to the first and second handle, and a plurality of tool components. The multi-tool further includes a locking mechanism that includes an engagement member, a pin, and a biasing element. When the first or second handle is in a locked position, the biasing element applies a force pushing the pin into engagement with the engagement member to secure the first or second handle. When the first or second handle is in an unlocked position, the pin is movable along the engagement member such that the first or second handle is pivotable. In a specific embodiment, the multi-tool including a pre-deployment mechanism configured to deploy the tool component at various angles thereby improving access and opening of the tool components.
