Adjustable Load Carrier Fastening with Integrated Toggle Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Securing transport objects like coils, slit strips, or circular blanks on load carriers in a vertical loading mode with minimal distance between them is challenging, as existing fastening methods are expensive and not always effective, requiring additional securing means like tension belts.
Innovation Solution
A fastening system with adjustable clamping elements, such as toggle levers or scissor linkages, integrated within tubular fasteners that can change their clear width to securely hold loads without additional securing means, allowing for easy adaptation to different load sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stanchions of different widths are used to secure transport objects of different dimensions, then the adaptability to various load sizes is improved, but the device complexity and cost increase
Solution Approach 1:
The fastening means incorporates an adjustable clear width mechanism that allows a single stanchion design to adapt to different load dimensions. The tensioning element can modify the distance between clamping elements, enabling one fastener type to secure various transport object sizes without requiring multiple fixed-width stanchions.
Solution Approach 2:
The fastening means is designed as a universal solution that can secure different types of transport objects (coils, slit strips, strip steel, wire rings, circular blanks) with a single fastener design. The adjustable clear width and repositionable clamping elements allow one fastener type to perform multiple securing functions across various load configurations.
2Reliability
If additional securing means such as tension belts are used to prevent cargo shifting, then the reliability of load securing is improved, but the device complexity and cost increase
Solution Approach 1:
The fastening means integrates multiple securing functions into a single device. The clamping elements provide lateral restraint while the adjustable clear width accommodates different load dimensions, eliminating the need for separate tension belts or additional securing means. The single fastener performs both positioning and securing functions.
Solution Approach 2:
The fastening means is designed to secure loads independently without requiring additional auxiliary securing elements. The clamping elements with adjustable positioning provide sufficient restraint forces to prevent cargo shifting, making the system self-sufficient and eliminating dependency on external tensioning devices.
3Productivity
If transport objects are arranged at minimal distance to maximize space utilization, then the productivity is improved, but the ease of operation for loading and unloading deteriorates
Solution Approach 1:
The fastening means divides the securing function into multiple repositionable clamping elements that can be independently positioned. This segmentation allows the fastener to adapt to loads at minimal distances by adjusting individual clamping point positions, maintaining ease of operation while maximizing space utilization through compact load arrangement.
4Reliability
If fixed-width stanchions are used to prevent cargo slipping, then the reliability of load securing is improved, but the adaptability to different transport object dimensions deteriorates
Solution Approach 1:
The fastening means transitions from fixed-width stanchions to a dynamic clear width design. The tensioning element enables continuous adjustment of the distance between clamping elements, allowing the same fastener to reliably secure transport objects of varying dimensions while maintaining securing reliability across different load sizes.
