Tool Friction Assembly for Single-Person Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tools such as spirit levels and heavy equipment parts often require stabilization on surfaces, but existing designs make it difficult for a single person to maintain their position, especially on vertical or overhead surfaces, due to shifting and the need for two-person operation.
Innovation Solution
Integration of high-friction and low-friction materials in tool designs, where low-friction materials allow easy movement and high-friction materials provide stabilization, enabling tools to be freely movable and fixed as needed, using assemblies with adjustable and retractable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a long and weighty level is used, then the level can provide accurate leveling over longer distances, but it becomes almost impossible for a single person to hold and position it accurately
Solution Approach 1:
The foot assembly incorporates a movable component that can transition between extended and retracted positions. When extended, it provides high friction to prevent slipping on vertical or overhead surfaces. When retracted, it reduces the overall footprint and allows easier handling by a single person. This dynamic adjustment resolves the contradiction between providing stable positioning for long levels and maintaining ease of single-person operation.
Solution Approach 2:
The friction coefficient of the foot assembly is changed by extending or retracting the movable component. In the extended position, high friction material contacts the surface to prevent slipping. In the retracted position, the friction characteristic changes to allow easier movement. This parameter change enables the level to provide both stable positioning and ease of operation.
2Stability of the object's composition
If high-friction materials are used on the tool feet, then the tool remains stable on the surface, but the tool becomes difficult to move or reposition
Solution Approach 1:
The foot assembly uses a movable component that can dynamically adjust its position. When the tool needs to be stable, the component extends to provide high friction contact with the surface. When the tool needs to be moved, the component can be retracting or repositioned to reduce friction. This dynamic mechanism resolves the contradiction between stability and ease of movement.
Solution Approach 2:
The foot assembly is segmented into fixed and movable portions. The movable portion can be independently adjusted to extend or retract, allowing the tool to transition between high-friction stable contact and low-friction easy movement. This segmentation enables the tool to provide both stability and ease of operation as needed.
3Length of stationary object
If the level is placed high above the person's head on a vertical surface, then the level can reach the required position, but it constantly shifts position and cannot be held steady
Solution Approach 1:
The movable component of the foot assembly extends when the level is placed against vertical or overhead surfaces, providing high friction to prevent slipping. This dynamic extension ensures that even when the level is positioned high above the user's head, it remains stable and does not constantly shift position, resolving the contradiction between reach distance and position stability.

AI summary
Apparatuses are provided for various tools that incorporate materials with a high coefficient of friction and a low coefficient of friction. The materials with a low coefficient of friction may be mounted on a tool and have a perpendicular movement to the tool. This perpendicular movement may be implemented with a spring mechanism. The materials with a high coefficient of friction may be mounted on the tool in a fixed position. The tool may be pressed against a surface, first engaging the materials with a low coefficient of friction. The tool may freely move across the surface while the materials with a low coefficient of friction maintain contact with the surface. As the tool is continually pressed to the surface, the materials with a high coefficient of friction subsequently make contact with the surface, thereby causing the lateral movement of the tool with respect to the surface to be restricted and stabilized. An example of the tool may be a spirit or carpenter level.
