Solution Overview

Problem

Aircraft floor heating systems rely on centralized control and power distribution units, limiting operational flexibility and increasing dependency on these systems, which can be a drawback in terms of scalability and fault tolerance.

Innovation Solution

Integration of a controller within each aircraft floor panel allows for localized control, reducing dependency on centralized systems and enabling networked or standalone operation, with ambient sensors and manual power level/temperature selection options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If centralized control and power distribution units are used, then system management is simplified, but operational flexibility and scalability are reduced

Engineering Contradiction:
Improvesystem managementVSAvoidoperational flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent divides the centralized control system into distributed intelligent modules, with each floor panel containing its own controller that can independently manage heating operations. This segmentation allows individual panels to operate autonomously while still being part of the overall system, thereby improving operational flexibility without completely abandoning system-wide coordination capabilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller within each floor panel is designed to dynamically adapt its operation based on local conditions such as temperature sensors, occupancy detection, and power availability. This dynamic capability enables the system to respond flexibly to changing operational requirements while maintaining simplified management through standardized control logic across all panels.

Inventive Principle:
Principle #15Dynamics

2Reliability

If centralized control systems are used, then coordination across multiple panels is improved, but dependency on centralized units increases

Engineering Contradiction:
Improvecoordination capabilityVSAvoidsystem independence
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

Each floor panel is equipped with its own intelligent controller that can function independently of the centralized system. This segmentation ensures that if the centralized control unit fails or is unavailable, individual panels can continue to operate based on their local sensors and pre-programmed logic, thereby reducing dependency while maintaining coordination capabilities through optional network connectivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The floor panel controllers are designed to autonomously monitor local temperature conditions, adjust heating output accordingly, and manage their own power consumption without requiring constant intervention from the centralized system. This self-service capability reduces dependency on centralized units while maintaining system-wide coordination when needed.

Inventive Principle:
Principle #25Self-service

3Device complexity

If all panels are connected to the same controller, then power distribution is simplified, but fault tolerance is reduced

Engineering Contradiction:
Improvepower distributionVSAvoidfault tolerance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The power distribution architecture is segmented so that each floor panel has its own power management circuitry and can draw power independently from the aircraft's electrical system. This segmentation means that a power distribution failure affecting one panel does not necessarily impact other panels, thereby improving fault tolerance while maintaining simplified power connection interfaces through standardized outlets.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller includes built-in diagnostic capabilities and backup logic that can detect faults in the power supply or heating elements before they cause complete system failure. This beforehand cushioning allows the panel to switch to alternative power sources or safe operating modes, maintaining reliability while keeping the power distribution system relatively simple.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

An aircraft heated floor panel (10) comprising a heat-generating layer (20) including an electric heater (52) having current supply lines (54) and a controller (60) which controls the current supplied to the heater (52) via the supply lines (54) to thereby control the heat generated by the layer (20). The controller (60) is integrated into the floor panel (10) whereby the panel has a stand-alone control system which need only be connected to the on-board power source of the aircraft, but can be connected to a main controller for networking or other purposes.
