Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for connecting trusses to structural components in building frameworks rely heavily on installer skill for correct bracket location and fastening, with the adequacy of the connection often difficult to verify.
Innovation Solution
A method involving the use of a block with pre-applied fasteners that secure the truss to a structural component, ensuring correct relative positioning and preventing translational displacement, allowing for easy and reliable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional brackets with fasteners are used to interconnect framework components, then visual inspection of bracket location is possible, but installer skill is critical and adequacy of fastening cannot be verified
Solution Approach 1:
The fastener is pre-applied to the bracket in a controlled manufacturing environment, ensuring correct positioning and pre-verifying adequacy before the bracket is installed on site. This preliminary action transfers the skill requirement from installation to manufacturing, where verification is more feasible.
Solution Approach 2:
The patent introduces an intermediary verification mechanism through the pre-applied fastener configuration, which serves as a tangible indicator of proper installation. The fastener's pre-positioned state acts as a mediator that communicates installation adequacy without requiring complex inspection procedures.
2Reliability
If heavy reliance is placed on installer skill for reliable interconnection, then connection integrity may be achieved, but process complexity and training requirements increase
Solution Approach 1:
The pre-applied fastener system is designed to be self-verifying, where the fastener's configuration and positioning automatically indicate correct installation without requiring complex inspection procedures or highly skilled installers. The system serves itself by providing built-in verification cues.
Solution Approach 2:
The patent changes the state of the fastener from a hidden internal component to a pre-positioned visible element, transforming the verification parameter from invisible fastening adequacy to visible fastener positioning. This parameter change simplifies the installation process and reduces dependency on installer skill.
3Manufacturing precision
If fasteners are pre-applied to ensure correct positioning, then sliding between components is precluded, but assembly flexibility is reduced
Solution Approach 1:
The fastener is pre-applied to the bracket during manufacturing with precise positioning, establishing correct geometry before installation. This preliminary action ensures manufacturing precision while maintaining assembly flexibility because the pre-positioned fastener becomes part of the bracket assembly that can still be moved and positioned during installation.
