Safety Deck Brace With Angled Engagement Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety decking systems are time-consuming to assemble and prone to overtightening, which can deform scaffold members and reduce strength, leading to potential point failures and safety hazards.
Innovation Solution
A brace with spaced apart wing portions and an angled engagement portion is designed to rapidly and securely couple diagonal and standard components, allowing for rapid assembly and improved stability by positioning the diagonal relative to the standard, and can be used at various locations within the safety deck assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tube clamps with threaded rods and nuts are used to connect diagonal bracing members to standards, then the connection can be tightened and loosened, but the assembly process becomes time-consuming and prone to overtightening
Solution Approach 1:
The invention extracts the time-consuming threaded rod and nut mechanism from the connection system. Instead of using traditional threaded fasteners that require winding and tightening, the patent employs a simple pin insertion system where the connection is achieved by directly inserting a pin through aligned holes in the wing portions and tube, eliminating the multi-step tightening process
Solution Approach 2:
The invention inverts the traditional fastening approach by replacing the tightening mechanism (threaded rod and nut) with a simple insertion mechanism. Instead of progressively tightening a connection, the design uses pre-aligned holes that require only straightforward pin insertion, reversing the complex sequential operation into a simple single-action connection
2Strength
If tube clamps are overtightened to form strong connections, then the connection strength increases, but the scaffold members deform leading to point failure
Solution Approach 1:
The invention introduces the pin as an intermediary element that transfers load between the wing portions and the tube without requiring high clamping forces. The pin acts as a direct load-bearing mediator that distributes stresses evenly across the connection interface, preventing the localized deformation and stress concentration that occurs with overtightened tube clamps
Solution Approach 2:
The invention changes the fundamental parameter of connection mechanics from high-contact-pressure friction-based fastening to low-pressure pin insertion. By altering the connection mechanism from threaded fasteners that rely on high clamping force to a pin system that relies on geometric interlocking and distributed load transfer, the design eliminates the risk of deformation while maintaining connection strength
3Manufacturing precision
If tube clamps need to be installed at specific times during assembly, then proper positioning is achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The invention applies preliminary action by providing pre-drilled and pre-aligned holes in the wing portions and tube before the actual connection is made. The alignment features and hole positions are predetermined during manufacturing, so that when components are brought together, the pins can be inserted directly without requiring complex positioning or adjustment during assembly
Solution Approach 2:
The wing portions are designed with universal features that can accommodate different tube positions and orientations. The spaced-apart wing portions with aligned holes create a versatile connection system that can adapt to various assembly configurations without requiring different components or complex positioning procedures for different installation scenarios
