Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling and positioning of large, heavy temporary wall braces in construction sites is labor-intensive, time-consuming, and poses safety risks due to the need for substantial manpower and machinery, leading to inefficiencies and increased costs.
Innovation Solution
A temporary brace cart equipped with a frame, wheels, a bracket for coupling to vehicles, a hoist, and a winch system that allows for easy transportation and precise positioning of braces using a boom lift or other machinery, reducing manual labor and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If temporary wall braces are made robust and sturdy to maintain panel stability, then the structural strength is improved, but the weight and size of the braces increase significantly
Solution Approach 1:
The system divides the heavy braces into segments that can be individually handled and transported on the cart, with the cart itself being movable and separable from the braces. This allows the braces to be distributed and managed in smaller, more manageable units rather than handling extremely heavy individual pieces.
Solution Approach 2:
The cart system acts as an intermediary between the heavy braces and the workers/machinery. The cart with its hoist and winch mechanisms serves as a mediating device that enables the handling of heavy braces without requiring direct manual lifting or complex heavy-duty machinery for each positioning operation.
2Strength
If heavy temporary braces are used to ensure panel stability, then the structural strength is improved, but the ease of operation deteriorates due to labor-intensive handling
Solution Approach 1:
The cart system provides self-service capabilities through its integrated hoist and winch mechanisms that can automatically lift and position braces without requiring extensive manual intervention. The system serves itself by having built-in mechanisms for its own operation, reducing the need for external heavy machinery and manual labor.
Solution Approach 2:
The cart acts as an intermediary device that simplifies the operation of handling heavy braces. Instead of workers directly manipulating extremely heavy braces or requiring complex heavy-duty machinery, the cart system mediates the interaction between the braces and the operators, making the process more manageable and easier to control.
3Strength
If heavy temporary braces are used to maintain panel stability, then the structural strength is improved, but the productivity decreases due to time-consuming positioning operations
Solution Approach 1:
The cart system with its self-contained hoist and winch mechanisms enables quick and efficient positioning of braces without requiring external heavy machinery or extensive manual intervention. This self-service capability significantly reduces the time required for brace installation and improves overall construction productivity.
Solution Approach 2:
The cart system allows for preliminary positioning and preparation of braces before final installation. The hoist and winch mechanisms enable braces to be pre-positioned and held in place, facilitating faster and more efficient final installation compared to traditional methods that require complete manual positioning from scratch.
4Strength
If heavy temporary braces are used to ensure panel stability, then the structural strength is improved, but the safety deteriorates due to increased risk of worker injuries
Solution Approach 1:
The cart system serves as a protective intermediary between workers and the extremely heavy braces. By using the cart's hoist and winch mechanisms to handle and position braces, workers are shielded from the direct risks of manual handling heavy loads, significantly reducing the potential for strains, sprains, and other musculoskeletal injuries.
Solution Approach 2:
The self-contained cart system with its own lifting and positioning mechanisms reduces the need for workers to directly handle heavy braces, thereby minimizing exposure to safety risks. The system essentially protects itself and its operators by automating the hazardous lifting and positioning operations.

AI summary
A temporary brace cart features a frame, a plurality of wheels for moving the frame, a bracket for coupling the frame to a vehicle (e.g., boom lift or other machine), a hoist extending vertically from the frame, a hoist arm extending from the hoist, and a winch coupled to the end of the hoist arm. In some uses, a plurality of temporary braces are positioned longitudinally along the frame for transport. A boom lift or other machine tows the cart to the desired location. Once at position, a cable may extend from the winch to a temporary brace. The winch may then be actuated so as to raise one end of the temporary brace, where it may be held until secured to the wall and ground by a worker.
