Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cargo handling systems in aircraft are burdened with extra weight due to the inclusion of legacy physical control interfaces for redundancy, even as they transition to wireless technology.
Innovation Solution
A cargo handling system featuring a wireless adapter that couples to a system controller via a proprietary non-standard connector, enabling wireless control of power drive units and providing indicators for connection status and system errors, utilizing NFC, Wi-Fi, Bluetooth, Zigbee, or infrared spectrum for communication, and allowing for secure and lightweight operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If legacy physical control interfaces are included for redundancy, then system reliability is improved, but system weight increases
Solution Approach 1:
The patent extracts and removes the legacy physical control interfaces from the cargo handling system, retaining only the essential wireless control functionality. This eliminates the redundant hardware components that added weight while maintaining system reliability through the wireless control architecture.
Solution Approach 2:
The patent replaces the mechanical physical control interfaces with a wireless electronic control system. The wireless adapter and wireless control device substitute for the legacy physical panels, eliminating mechanical components while maintaining control functionality and improving reliability through electronic redundancy.
2Weight of moving object
If wireless technology is implemented, then system weight is reduced, but system complexity increases
Solution Approach 1:
The patent introduces a wireless adapter as an intermediary component that bridges the legacy system controller and the wireless control device. This intermediary handles the complexity of wireless communication protocols and data translation, isolating the complexity from the main system while maintaining weight reduction benefits.
Solution Approach 2:
The wireless adapter serves multiple functions including wireless communication, data translation, protocol handling, and system integration. By consolidating these diverse functions into a single multi-functional component, the patent reduces overall system complexity compared to implementing separate dedicated systems for each function.
3Ease of operation
If physical control panels are used, then ease of operation is maintained, but device complexity increases
Solution Approach 1:
The patent creates a wireless copy of the physical control panel functionality through the wireless control device. The wireless interface replicates the control commands and user interaction capabilities of the physical panels without requiring the physical hardware, thereby maintaining ease of operation while reducing device complexity.
