Solution Overview
Problem
Existing load binding systems for heavy and bulky cargo are inadequate as they often require complex maintenance, are not easily adjustable, and fail in adverse weather conditions, especially when dealing with variably sized and shaped loads.
Innovation Solution
A load binding apparatus with minimal moving parts, utilizing standard chains and cables, featuring a threaded fastener for continuous adjustment and easy installation/removal by one or two operators, with chain couplers at opposed ends to secure loads effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ratcheting systems are used for load binding, then load securing function is provided, but adjustment to optimize tension for various load sizes is difficult due to fixed displacement per cycle
Solution Approach 1:
The patent replaces the fixed-step ratcheting mechanism with a dynamic, continuously adjustable threaded fastener system. The tie bolt with external threads engages with a threaded aperture, allowing operators to adjust the binder length incrementally by rotating the bolt, thereby optimizing tension for any load size without being constrained by fixed displacement cycles.
Solution Approach 2:
The invention changes the adjustment parameter from fixed discrete steps (ratchet teeth) to continuous variable adjustment (threaded rotation). The threaded fastener allows fine-tuning of the binder length by controlling the rotation amount, enabling precise tension optimization for diverse load configurations.
2Reliability
If woven straps are used in ratchet systems, then load binding is achieved, but reliability deteriorates in cold weather as straps fray and become brittle
Solution Approach 1:
The patent replaces the reusable but weather-vulnerable woven straps with a disposable-style approach using standard chains and cables. These alternative materials do not become brittle in cold weather and can be easily replaced if damaged, maintaining reliability across all weather conditions without the maintenance burden of protecting woven straps.
Solution Approach 2:
The invention uses composite construction by combining a metal threaded fastener body with separate chain or cable binding elements. This composite approach allows each component to be optimized for its function: the metal fastener provides weather-resistant adjustment mechanism while chains/cables provide durable, temperature-independent binding strength.
3Adaptability or versatility
If geared systems are used for load binding, then adjustment capability is provided, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent extracts and removes the complex geared mechanism entirely, replacing it with a simple threaded fastener system. By taking out the unnecessary gears and complex transmission components, the invention achieves adjustment capability through the straightforward threading action, dramatically reducing device complexity and eliminating maintenance requirements.
Solution Approach 2:
Instead of using a complex geared system to multiply small rotational inputs into linear adjustment, the invention inverts the approach by using direct threading where the rotation of the tie bolt directly converts to linear displacement through the thread geometry. This simpler mechanical advantage approach eliminates the need for intermediate gear mechanisms.
4Reliability
If complex load binding systems are used, then load securing function is provided, but ease of installation and removal deteriorates requiring extensive training
Solution Approach 1:
The patent segments the load binding system into simple, modular components: a first part, a second part, and a chain or cable. This segmentation allows operators to easily assemble and disassemble the binder by connecting and disconnecting the parts, reducing installation complexity while maintaining secure load binding capability.
Solution Approach 2:
The invention uses universal standard chains and cables that can be used with various loads and configurations. The threaded fastener mechanism serves multiple functions: adjustment, locking, and tensioning. This multi-functionality reduces the need for specialized components and training, allowing operators to master a single simple system for diverse applications.
