Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screed beam support apparatuses require tools for operating set screws, increasing setup time and making it cumbersome, especially for multiple installations.
Innovation Solution
A clamp with an elongated handle perpendicular to the set screw, allowing for lever action to apply torque without the need for tools, and a hook for supporting the screed beam at a desired height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hex head set screw is used for securing the clamp to the post, then the fastening is secure, but a tool is required for operation which increases setup time and makes operation cumbersome
Solution Approach 1:
The set screw incorporates an integrated T-shaped handle that allows the user to tighten and loosen the screw by hand without requiring external tools. The handle serves the dual purpose of both fastening mechanism and operating tool, enabling self-service operation that eliminates the need to locate and use separate wrenches or screwdrivers.
Solution Approach 2:
The patent combines the set screw fastening mechanism with an integrated T-shaped handle into a single unified component. This merging of the fastening element and the operating tool allows the user to directly manipulate the set screw with hand torque, eliminating the need for separate tools while maintaining secure fastening capability.
2Volume of moving object
If a compact grip is used for hand-tightening the set screw, then the device size is reduced, but the surface area for applying torque is limited which may cause slippage
Solution Approach 1:
The set screw transitions from a compact circular grip to an elongated T-shaped handle that extends in a direction perpendicular to the screw axis. This dimensional change provides a larger lever arm and increased surface area for torque application, reducing slippage while maintaining a compact overall device profile through the perpendicular orientation.
Solution Approach 2:
The handle is segmented into an elongated shape with distinct sections that provide optimal leverage points. The T-shape creates separate functional zones: the horizontal arms provide leverage for torque application while the vertical portion interfaces with the screw head, allowing efficient force distribution and reducing slippage during operation.
3Adaptability or versatility
If multiple clamps are installed on different posts, then the screed beam can be supported at multiple positions, but locating and operating tools for each clamp increases the time spent
Solution Approach 1:
Each clamp is equipped with an integrated T-shaped handle on its set screw, allowing workers to quickly tighten and loosen multiple clamps throughout the installation process without needing to locate, transport, or manage separate tools. This self-service capability dramatically reduces setup time when installing multiple clamps at different post locations.
Solution Approach 2:
The T-shaped handle design provides universal functionality across all clamp installations. The same integrated handle mechanism works identically for every clamp, whether installing the first clamp or the tenth clamp, eliminating the need for different tools or procedures and streamlining the overall installation process for multiple positions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick and efficient installation of screed beam supports by enabling tool-free operation, reducing slippage and enhancing torque application.
Implementation Method 1
The increased radially extending surface area reduces slippage during operation
Implementation Method 2
The set screw is rotatable to move the set screw alternately toward and away from the second portion. The set screw and the second portion of the body are configured to cooperatively clamp the post therebetween
Implementation Method 3
The handle is coupled to the set screw outside of the channel and is elongated between a pair of ends and is oriented perpendicularly to the set screw

AI summary
A screed beam support apparatus for supporting a screed beam at a desired height above a ground surface includes a clamp and a hook. The clamp secures the hook to a vertical post to position the screed beam at the desired height. The clamp uses a set screw with a handle that extends perpendicularly to the set screw. The handle facilitates increasing a torque applied to the set screw by a user via a lever action.
