Multi-tool Assembly Integrating Blade and Writing Utensil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drywall workers face inefficiencies and safety hazards due to the need to frequently switch between writing utensils and utility knives, which can be distracting and potentially dangerous as they handle sharp blades.
Innovation Solution
A hand-held multi-tool assembly with a housing that integrates a blade and a slot for a secondary tool, allowing quick and safe switching between tools without putting them down, featuring a set screw for secure engagement and a design that accommodates writing utensils for drawing patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If workers carry multiple separate tools (pencil and utility knife), then they can perform both drawing and cutting functions, but they must repeatedly take out and put away tools which increases time consumption and safety risks
Solution Approach 1:
The patent combines a utility knife blade and a writing utensil (pencil or marker) into a single integrated housing structure. The blade is disposed within the housing and can be extended, while the writing utensil is held in a recess within the same housing. This merging allows workers to switch between cutting and drawing functions by simply rotating or adjusting the housing, eliminating the need to put down and pick up separate tools, thereby reducing time loss and maintaining productivity.
2Adaptability or versatility
If workers carry multiple separate tools, then they can perform different functions, but the repeated handling of sharp blades creates safety hazards
Solution Approach 1:
By integrating both the blade and writing utensil into one housing, the patent reduces the frequency of handling the blade. The blade remains enclosed within the housing and can be extended only when needed for cutting, while the writing utensil is accessible in the recess for drawing. This unified design minimizes repeated exposure to the sharp blade, thereby reducing safety hazards while maintaining functional versatility.
Solution Approach 2:
The writing utensil is nested within the housing structure, specifically held in a recess that is part of the same housing that contains the blade. This nesting arrangement allows both tools to coexist in a compact form, with the writing utensil positioned such that it can be accessed without requiring the blade to be extended or handled separately, thus reducing safety risks.
3Manufacturing precision
If workers use separate tools for drawing and cutting, then they can perform each function adequately, but the switching process is distracting and reduces focus on the task
Solution Approach 1:
The integrated housing design allows workers to maintain focus on the drywall surface while switching between drawing and cutting functions. By rotating or adjusting the housing to access either the blade or the writing utensil, workers can perform function switches without looking away from or distracting themselves from the task at hand, thereby maintaining both precision and ease of operation.

AI summary
An improved multi-tool assembly which includes a housing that extends between opposing first and second longitudinal ends is provided. The multi-tool assembly further includes a blade which is partially disposed within the housing and which projects out of the first longitudinal end of the housing. The housing has a slot which opens to the second longitudinal end of the housing and at least one tool engaging element disposed at least partially within the slot of releasably securing a tool in the slot at the second longitudinal end of the housing such that the tool projects out of the second longitudinal end of the housing.
