V-Shaped Wire Support Member for Aircraft ECS Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing aircraft environmental control systems (ECS) face challenges in routing and supporting wiring to prevent interference and wear, which can disrupt the communication between the pack control unit and cabin air compressor modules across varying flight conditions.
Innovation Solution
A wire support assembly with V-shaped wire support members and flanges that securely route and support wiring bundles, minimizing contact with other components and preventing wear, while maintaining lightweight and compact design to ensure continuous communication between the pack control unit and modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wiring is routed through the ECS without dedicated support members, then the system structure remains simple, but the wiring will interfere with other parts and wear through
Solution Approach 1:
The patent introduces wire support members as intermediary components between the wiring and the ECS structure. These support members act as mediators that protect the wiring from direct contact with moving parts while maintaining proper routing and organization within the confined ECS space.
Solution Approach 2:
The wiring system is segmented into multiple supported sections using discrete wire support members positioned at critical locations. This segmentation allows the wiring to be protected at specific vulnerability points without requiring a continuous complex support structure throughout the entire ECS.
2Reliability
If wire support members are added to route and protect wiring, then wiring wear is prevented, but the device complexity increases
Solution Approach 1:
The wire support members are designed to perform multiple functions simultaneously: they provide mechanical support for the wiring, prevent wear through proper spacing, maintain organized routing, and protect communication continuity. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The patent specifies precise geometric parameters for the wire support members, including a ratio of length L1 to diameter D1 between 2.0 and 2.3. This parameter optimization ensures adequate wiring clearance and wear prevention while minimizing the size and complexity of the support members themselves.
3Volume of moving object
If wiring is closely routed to minimize space, then the ECS remains compact, but the wiring is more susceptible to wear and interference
Solution Approach 1:
The wire support members create a third dimensional layer for wiring placement within the ECS. By elevating or positioning wiring on support members rather than laying it flat against surfaces, the design provides wear protection while maintaining compact overall dimensions through efficient vertical or lateral spacing.

AI summary
A wire support member for supporting the wiring of an environmental control system. The wire support member has a base edge, a first edge, and a second edge, the first and second edges form a V-shaped apex opposite the base edge. The ratios of the diameter of a first fastener opening through the wire support member to a length from the center of the first fastener opening to the first edge, and of the diameter of the first fastener opening to a length from the center of the first fastener opening to the second edge optimize the routing and support for the wiring.
