Auxiliary Strap Assembly With Anchor Body For Load Bearing Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strap assemblies for load-bearing platforms are flexible and lack structural support, often deforming the platform during tightening and failing to securely mount objects.
Innovation Solution
An auxiliary strap assembly with an elongate anchor body and a cam lock arrangement that provides adjustable support, featuring a canted slot and pivotally coupled lock body to securely attach and adjust the strap, ensuring alignment and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible straps are used for mounting objects, then the straps can be easily adjusted and installed, but they fail to provide structural support and deform the load bearing platform during tightening
Solution Approach 1:
The strap assembly is divided into distinct functional segments: a rigid anchor body for structural support, a flexible strap for adjustment, and a cam lock mechanism for secure fastening. This segmentation allows each component to perform its specialized function without compromising the others.
Solution Approach 2:
The assembly combines rigid materials (anchor body, cam lock) with flexible materials (strap) to create a composite system that exhibits both structural strength and flexibility. The rigid components provide platform support while the flexible strap enables adjustment.
2Strength
If rigid structures are used to provide structural support, then structural strength is improved, but the ability to adjust and conform to different positions is reduced
Solution Approach 1:
The cam lock mechanism introduces dynamic adjustability to the otherwise rigid anchor body. The strap can be positioned at various lengths and securely locked, allowing the rigid structure to adapt to different mounting requirements while maintaining structural integrity.
Solution Approach 2:
The anchor body serves multiple functions: providing structural support, enabling adjustment through the strap, and ensuring secure fastening via the cam lock. This multi-functionality allows a single rigid component to address both strength and adaptability requirements.
3Ease of manufacture
If traditional straps are used for tightening, then installation is simple, but they deform the shape of the load bearing platform
Solution Approach 1:
The rigid anchor body acts as an intermediary between the flexible strap and the load bearing platform. It distributes the tightening forces across a larger area through its rigid structure, preventing the flexible strap from directly deforming the platform while maintaining simple installation procedures.
4Reliability
If adjustable mechanisms are added to provide secure mounting, then mounting reliability is improved, but device complexity increases
Solution Approach 1:
The cam lock mechanism is designed to be self-locking through its geometric configuration. Once the strap is tensioned, the cam lock automatically engages and maintains secure mounting without requiring additional fastening actions or complex control systems, thereby limiting the increase in device complexity.

AI summary
An auxiliary strap assembly provides a simple, adjustable strap device for mounting objects to an underlying load bearing platform. In some implementations, the strap assembly includes an elongate anchor body that provides support to the object(s) being secured and/or to the underlying load bearing platform. The strap assembly can be adapted for connection to ladder webbing, such as Pouch Attachment Ladder System (PALS) or HEXGRID® mounting system.
