Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary restraint assemblies for cargo in aircraft cargo compartments are inefficient and require manual operation, lacking automation and often require additional components, which can complicate integration with smart cargo compartment features.
Innovation Solution
A fully automated cargo restraining system utilizing a worm gear and motor mechanism, integrated with a controller, that extends and retracts a restraint head to secure cargo, reducing the number of components and enabling seamless integration with other smart cargo features, with a gear assembly and worm gear ratio optimized for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used for auxiliary restraint assemblies, then device complexity is reduced, but ease of operation deteriorates and productivity decreases
Solution Approach 1:
The patent replaces manual mechanical operation with an automated motor-driven system. The motor assembly rotates the ball panel automatically, eliminating the need for manual intervention while managing complexity through integrated control mechanisms.
Solution Approach 2:
The restraint assembly is designed to automatically secure cargo without requiring external manual operation. The system self-activates through the motor-driven rotation mechanism, performing the restraint function autonomously once initiated.
2Adaptability or versatility
If additional components are added to auxiliary restraint assemblies, then functionality is improved, but device complexity increases
Solution Approach 1:
The ball panel assembly serves multiple functions: it acts as both a restraint mechanism and an integrative platform for smart cargo compartment features. This multi-functionality reduces the need for separate dedicated components, thereby managing complexity while enhancing adaptability.
Solution Approach 2:
The patent combines the restraint assembly with the ball panel structure, merging what could be separate components into a unified system. This integration reduces component count while maintaining the ability to incorporate smart features through the combined structure.
3Productivity
If gear assembly and worm gear ratio are optimized, then productivity is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes the worm gear ratio and gear assembly parameters to achieve high productivity in cargo restraint operations. By carefully selecting and adjusting these mechanical parameters, the system achieves efficient operation while balancing the required manufacturing precision through design optimization rather than extreme precision requirements.
