Load Restraint Apparatus with Slot and Hook Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for restraining loads during transportation, such as using flexible tape or chain, are inadequate in preventing fore-and-aft movement and sideways sway due to variations in load mass, friction, and vehicle dynamics.
Innovation Solution
The use of an apparatus with a slot and hook-shaped components to secure tape or chain around loads, allowing for easier installation and removal, and providing enhanced lateral and longitudinal restraint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple restraints are used to reliably secure loads, then load stability is improved, but device complexity and time for installation/removal increase
Solution Approach 1:
The patent combines multiple restraint functions into a single integrated restraint unit that can simultaneously secure multiple load items. The restraint system incorporates multiple attachment points and routing paths within one unit, allowing it to perform the work of multiple separate restraints while simplifying installation and removal operations.
Solution Approach 2:
The restraint unit is designed with universal attachment mechanisms that can secure various types of load items (pallets, boxes, drums) using a single device design. The restraint incorporates multiple functional elements including attachment points, routing paths, and securing mechanisms that can adapt to different loading configurations, reducing the need for multiple specialized restraints.
2Reliability
If multiple restraints are used to prevent load movement, then load stability is improved, but time for releasing and re-fixing restraints increases
Solution Approach 1:
By combining multiple restraint functions into a single unit with integrated attachment and release mechanisms, the patent enables simultaneous securing and releasing of multiple load items. The unified design allows operators to attach or detach entire restraint units in one operation rather than individually adjusting multiple separate restraints, significantly reducing time loss during delivery operations.
3Reliability
If tape is stretched taut over load to restrain it, then load restraint effectiveness is improved, but tape friction and wear increase
Solution Approach 1:
The patent introduces friction-reducing intermediaries such as low-friction coatings, lubricated surfaces, or protective layers between the tape and load items. These intermediary elements allow the tape to maintain sufficient restraint force while reducing direct friction and wear on the tape material, extending its service life and maintaining restraint effectiveness.

AI summary
A load (22, 26, 27, 28, 29) is restrained against movement by passing a tape or chain (21, 31, 39) around the load (22, 26, 27, 28, 29) and passing the tape or chain (21, 31, 39) through a slot (17, 44) in a plate or the like (14, 41).
