Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tensioning brackets and systems for securing building parts, such as straps and girders, require on-site adaptation and connection, leading to potential worker errors and increased loads during construction, especially under extraordinary conditions like strong winds or settling structures, necessitating a stronger and safer installation method.
Innovation Solution
A tensioning bracket with a design featuring a first and second body section connected via a common section, allowing pins to align with holes for direct force transfer, along with a tensioning nut for secure locking and force distribution, enabling easy and safe installation and minimizing the risk of faults during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If on-site adaptation and connection of straps and brackets is performed, then the tensioning system can be customized to fit specific building parts, but the risk of worker errors increases and installation safety decreases
Solution Approach 1:
The bracket is pre-assembled with pins and holes in specific patterns before delivery to the construction site. This preliminary preparation ensures proper alignment and connection geometry, eliminating the need for workers to perform complex on-site adaptation while maintaining customization capability through different pre-configured bracket designs.
2Adaptability or versatility
If on-site connection of bracket and straps is performed, then the installation can be adapted to specific needs, but the complexity of the installation process increases
Solution Approach 1:
The bracket is divided into distinct functional segments: body sections for structural support, a common section for bending and connection, and pre-formed pins and holes for strap attachment. This segmentation allows each component to be independently manufactured and then easily assembled on-site, reducing overall installation complexity while maintaining adaptability.
3Ease of manufacture
If traditional connection methods are used, then existing installation procedures can be maintained, but the force distribution becomes uneven and structural integrity decreases
Solution Approach 1:
The bracket design incorporates asymmetric pin and hole patterns in the body sections that are specifically configured to align with corresponding features on the straps. This asymmetric arrangement ensures that forces are distributed evenly across multiple connection points, preventing stress concentration and improving structural integrity while maintaining straightforward installation procedures.
4Adaptability or versatility
If the bracket design requires multiple separate components, then manufacturing flexibility increases, but the number of parts increases and manufacturing cost increases
Solution Approach 1:
Multiple functional elements are merged into a single integrated bracket component: the body sections, common section, pins, and holes are all formed as one piece through bending and shaping operations. This consolidation reduces the total number of parts, simplifies manufacturing processes, and lowers costs while maintaining the design flexibility needed for different application requirements.

Function Achieved in This Case
The solution provides a strong, safe, and cost-effective tensioning system that ensures even force distribution and easy installation, reducing the risk of worker errors and material costs, while maintaining structural integrity under varying loads.
Implementation Method 1
the pull in the tensioning bracket is transferred from the pulling means to the tensioning bracket and then via the pins and holes to the perforated band substantially in a straight line
Implementation Method 2
when bending the element along a bending line in the common section the pins of the first section are received in holes of the second body section
Implementation Method 3
the tensioning bracket provides an even distribution of forces from the one part to the other
