Speed striker multi-function masonry tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Masons often need to switch between multiple tools frequently for various tasks in masonry, leading to a cluttered and inefficient work site, as existing tools do not combine multiple functions into a single implement effectively.
Innovation Solution
A multifunction masonry tool with a four-sided polygonal handle and integrated loop and pick components, where the handle is designed for a firm grip and the loop and pick are formed from a single piece of hardened steel rod, allowing for tasks like cutting mortar and striking materials with a single hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate masonry tools are used for different tasks, then each tool can be optimized for its specific function, but the work site becomes cluttered and tool switching becomes frequent and inefficient
Solution Approach 1:
The patent combines a pick tool and a mortar jointer tool into a single dual-function implement. The pick end includes a hardened steel pick for striking and breaking masonry materials, while the jointer end includes a loop-shaped blade for cutting and shaping mortar joints. This merging eliminates the need to carry and switch between two separate tools, reducing work site clutter while maintaining both specialized functions.
Solution Approach 2:
The masonry tool is designed with universal applicability by incorporating multiple functions in one implement. The handle is configured to accommodate both the pick and jointer components, allowing a single tool to perform diverse masonry tasks including striking, breaking, cutting mortar, and shaping joints, thereby serving multiple purposes that previously required separate specialized tools.
2Productivity
If a single hand tool is designed to perform multiple masonry functions, then tool switching is reduced and work site clutter is minimized, but the tool design becomes more complex
Solution Approach 1:
The masonry tool is segmented into distinct functional components: a handle portion, a pick end with hardened steel point, and a jointer end with loop-shaped blade. Each segment performs a specific function, and the segmentation allows the tool to be manufactured by forming these components separately and assembling them, thereby managing structural complexity while maintaining multiple functions.
Solution Approach 2:
The tool employs composite construction by combining different materials for different components. The handle is made of a durable material to provide grip and structural support, while the pick end uses hardened steel for striking durability, and the jointer end uses a loop-shaped blade material suitable for cutting mortar. This composite approach allows each component to be optimized for its specific function while integrating into a single tool.
3Ease of operation
If the handle is designed with a narrow neck for enhanced finger grip, then dexterity and control are improved, but the overall handle structure becomes more complex
Solution Approach 1:
The handle features a localized neck region with reduced diameter that provides enhanced grip control for the user's fingers. This local quality change is concentrated in one specific area of the handle rather than affecting the entire structure, allowing improved dexterity for precise operations while maintaining a relatively simple overall handle geometry that is easy to manufacture.

AI summary
A multifunction masonry tool includes a handle adapted to be held firmly in the grip of one hand. The handle is a polygonal solid, with for example four sides arrayed in generally rectangular or square cross-sectional arrangement. A narrow neck is disposed adjacent to a first end of the handle to enhance the grip of the thumb and forefinger. A loop extends from one end of the handle and a pick extends from the opposed end, both formed of a hardened, form-retaining rod material. The pick and loop may be formed from a single piece of the rod material that extends axially through the handle.
