Equipment Mounting Baseplate With Cable Recess for Aircraft Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mounting and connecting electrical equipment housings in aircraft are inflexible, requiring pre-determined cable lengths and positions, which limits adaptability during assembly, maintenance, and reconfiguration, and exposes cables to damage during transportation and reconfiguration.
Innovation Solution
A modular fixing baseplate with a spacer, cable ties for winding cables, and a connector support with a locking device allows for adjustable cable lengths and positions, enabling flexible configuration of electrical equipment items within the aircraft's interconnection network, allowing for safe storage and adaptation of cable lengths without exposing excess cable lengths to damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pre-determined cable lengths and positions are used for mounting electrical equipment, then the initial installation is simplified, but adaptability during assembly, maintenance, and reconfiguration is limited
Solution Approach 1:
The base plate is divided into functional zones: a fixing base for mounting equipment, a storage recess for cable management, and a connector support for interconnections. This segmentation allows each zone to be optimized independently, enabling simplified initial installation while maintaining adaptability through modular cable storage and reconfigurable connector positions.
2Device complexity
If fixed cable routing is implemented, then cable paths are predetermined and simple, but cables are exposed to damage during transportation and reconfiguration
Solution Approach 1:
The storage recess is prepared in advance on the base plate, allowing cables to be neatly wound and stored before final connection. This preliminary cable organization protects cables during transportation and enables easy reconfiguration without exposing cables to damage, as they can be temporarily stored in the recess rather than left exposed or tightly routed.
3Adaptability or versatility
If excess cable length is allowed, then adaptability for reconfiguration is improved, but excess cable is exposed to damage and creates disorder
Solution Approach 1:
The storage recess provides a nested structure where excess cable length can be wound and stored within the base plate assembly. This nesting solution allows adaptability for reconfiguration by providing available cable length, while simultaneously protecting the excess cable from damage and maintaining order by containing it within the recess rather than leaving it exposed.
4Ease of operation
If electrical equipment items are frequently mounted and dismounted, then maintenance and reconfiguration are enabled, but the interconnection network requires extensive rechecking
Solution Approach 1:
The base plate with standardized connector support and storage recess provides a universal mounting interface that maintains interconnection network integrity. This multi-functional design allows equipment to be mounted or dismounted while keeping the connector positions and cable routing paths consistent, reducing the need for extensive rechecking of the interconnection network during maintenance operations.
