Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an apparatus that can effectively deploy and move radar antennas between stowed and deployed positions, while also being transportable and capable of withstanding various environmental conditions, with efficient cooling and stability features.
Innovation Solution
The apparatus includes a platform with a screw-threaded drive element, a carriage, and a backstay system that allows the antenna to be rotated and positioned between stowed and deployed orientations, featuring self-cleaning and self-lubricating components, and adjustable stands for level mounting, along with a cooling system using centrifugal airflow cleaners and ducting for effective heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a device is designed to be stable in a propped orientation, then stability is improved, but the device becomes difficult to move between stowed and deployed positions
Solution Approach 1:
The propping apparatus employs a dynamic mechanism where the carriage moves along rails to adjust the backstay position, enabling the device to transition between stable propped orientation and movable stowed/deployed positions. The screw-threaded drive element provides controlled motion while maintaining stability during operation.
Solution Approach 2:
The device is divided into separate functional components: a platform, a movable carriage, a rotatable backstay, and a drive mechanism. This segmentation allows independent optimization of stability (through the braced propped configuration) and mobility (through the adjustable carriage and backstay system).
2Adaptability or versatility
If a radar antenna system is made transportable on a vehicle, then adaptability is improved, but the system becomes more complex
Solution Approach 1:
The platform serves multiple functions: it supports the antenna system during operation, provides a base for the propping mechanism, and facilitates transport on vehicles. The same structural elements are used for both operational and transport configurations, reducing overall system complexity despite enhanced versatility.
Solution Approach 2:
The propping mechanism, drive system, and transport platform are integrated into a unified structure where components serve dual purposes. The backstay and carriage assembly既能 provide operational stability又能 facilitate transport, merging multiple functions into a cohesive system.
3Temperature
If cooling components are added to manage heat, then temperature control is improved, but device complexity increases
Solution Approach 1:
The cooling system is designed to operate autonomously, with cooling components that self-regulate based on thermal conditions. The system provides necessary cooling functionality without requiring complex external control mechanisms, maintaining simplicity while achieving temperature management.

AI summary
Apparatus for propping a device, comprising a platform, a bracket, a carriage and a backstay. The backstay is rotatable relative to the carriage and to the device. The carriage can be moved in a first direction, which can causes a device to move between a stowed position and a deployed position. Apparatus comprising a rotatable assembly and a device movable between stowed and deployed positions, a center of rotation of the device in the deployed position being at or displaced only substantially vertically from a center of gravity of the rotatable assembly. Apparatus comprising a platform mounting portion, a platform structure rotatably mounted thereon, a duct extending through the platform mounting portion and into a space within the platform structure, whereby fluid can be passed through the duct and into the enclosed space while the platform structure is rotating relative to the mounting portion.
