Recessed Floor Fitting With Isolated Power and Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recessed floor fittings lack efficient and safe mechanisms to house and manage various electrical, data, and communication connections, particularly in environments where unauthorized access needs to be prevented, such as airports, and do not provide adequate isolation of high and low voltage components.
Innovation Solution
A recessed floor fitting with a poke-through housing, divider assembly, and feeder plates that separate high and low voltage components, featuring a cover with tamper-resistant fasteners and separate access doors for different voltage types, allowing secure and safe installation and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a recessed floor fitting houses multiple electrical and data connections, then functionality and versatility are improved, but device complexity and safety risks increase
Solution Approach 1:
The interior chamber is divided into multiple isolated compartments by partition walls. Each compartment houses specific types of connections (electrical outlets, data ports, communication interfaces) separately, preventing interference between different voltage types and signal lines while maintaining overall functionality
Solution Approach 2:
Different compartments are designed with specific characteristics suited to their function: electrical compartments have grounding features and proper clearance, data compartments have shielding for signal integrity, and each compartment type is optimized for its specific connection requirements
2Device complexity
If high and low voltage components are housed together, then device complexity is reduced, but safety hazards and electromagnetic interference increase
Solution Approach 1:
Partition walls create physically isolated compartments that separate high voltage electrical outlets from low voltage data and communication ports. This segmentation prevents electromagnetic interference between different voltage systems and eliminates safety hazards from improper contact between high and low voltage components
Solution Approach 2:
The partition walls act as intermediary barriers between high and low voltage compartments. These walls provide physical separation and can incorporate grounding features and shielding to prevent electromagnetic coupling while maintaining the integrated housing structure
3Reliability
If unauthorized access is prevented through secure mechanisms, then safety and security are improved, but ease of operation and installation difficulty increase
Solution Approach 1:
The access door is divided into multiple independently accessible sections, each providing access to specific compartments (e.g., data ports, communication interfaces). This allows users to access only the compartments they need without requiring full disassembly or specialized tools, maintaining security while improving ease of operation
Solution Approach 2:
The access door mechanism incorporates movable elements such as hinged sections or sliding panels that can be opened to different degrees. This dynamic design allows flexible access levels: full access for installation/maintenance and partial access for routine user operations, balancing security with operational ease

AI summary
A recessed floor fitting includes a poke-through housing, a divider assembly, and a feeder plate. The poke-through housing has a base and an outer wall with an open top that defines an interior chamber. The base includes a central aperture, a first perimeter aperture, and a second perimeter aperture. The divider assembly separates the interior chamber into a center portion, a first portion, and a second portion. The center portion is in communication with the center aperture. The first and second portions are in communication with the respective first and second perimeter apertures. The feeder plate is connected to the base, and has a mounting flange and a conduit extending from the mounting flange.
