Aircraft Floor Beam Wire Mounting Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing equipment in aircraft passenger cabins require modifications to floor beams, which can weaken the structure and introduce stress concentrations, and lack flexibility in relocating wiring or equipment, leading to high costs and delays.
Innovation Solution
A removable support bracket with a support body, cable cradles, and adjustable tension bolts that can be attached and removed from aircraft floor beams without modifying them, providing a universal, lightweight, and cost-effective solution for mounting wires, cables, and conduits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If drilling holes in floor beams to mount wiring and equipment, then mounting capability is improved, but structural strength deteriorates and regulatory approval complexity increases
Solution Approach 1:
A support bracket serves as an intermediary component between the floor beam and the wiring/equipment. The bracket attaches to the floor beam through its legs that fit over the beam, and provides mounting surfaces through arms and fastening mechanisms for cables and equipment, thus enabling mounting capability without drilling holes in the floor beam structure
Solution Approach 2:
The support bracket is divided into separate functional segments: legs for attachment to the floor beam, arms for supporting wiring and equipment, and fastening mechanisms for securing items. This segmentation allows the mounting function to be added without modifying the floor beam structure
2Adaptability or versatility
If drilling holes in floor beams to mount wiring and equipment, then mounting capability is improved, but regulatory approval time and cost increase
Solution Approach 1:
The support bracket is designed as a removable, non-permanent installation that does not require structural modification approval. While the bracket itself is a durable component, its installation method mimics temporary mounting solutions that bypass regulatory hurdles associated with permanent structural changes
Solution Approach 2:
By introducing the support bracket as an intermediary mounting solution, the need for direct structural modification is eliminated, thereby avoiding the regulatory approval process entirely and reducing installation time
3Strength
If using original design mounting brackets in newly built aircraft, then structural integration is improved, but flexibility in relocating wiring deteriorates
Solution Approach 1:
The support bracket is designed with removable and repositionable features, allowing it to be easily detached and relocated to different positions on the floor beam. The legs can be removed from one location and reattached elsewhere, providing dynamic adaptability that contrasts with fixed original design brackets
Solution Approach 2:
The bracket's segmented design with separate legs, arms, and fastening components enables easy disassembly and relocation. Each segment can be independently positioned or replaced, providing flexibility not available in integrated original design brackets
4Adaptability or versatility
If modifying floor beams for equipment installation, then mounting capability is improved, but device complexity increases
Solution Approach 1:
The support bracket serves as a self-contained intermediary system that provides all necessary mounting functions in one component. It includes integrated legs for attachment, arms for support, and fastening mechanisms, eliminating the need for complex structural modifications and multiple separate installation components

Function Achieved in This Case
Enables secure and flexible mounting of wires, cables, and conduits to aircraft floor beams without altering the structure, reducing the risk of metal fatigue and allowing for easy relocation, thus minimizing costs and delays associated with regulatory approvals.
Implementation Method 1
at least clamping block connected to the support body with at least one adjustable tension bolt, the clamping block having a beam engaging surface wherein tension in the at least one bolt urges the beam engaging surface toward the support body
