Solution Overview

Problem

Existing heater assemblies for water system ports are inefficient due to wasted heat, damage susceptibility, and complex assembly requirements, particularly in extreme environmental conditions like low temperatures and movement.

Innovation Solution

A heater assembly with a heat conducting element embedded in the housing, forming loops around port openings, using carbon nanotube material for efficient heat transfer and reduced energy consumption, along with a simple and adaptable design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a heater assembly is provided to heat ports in extreme environments, then freezing protection is improved, but heat efficiency deteriorates due to wasted heat

Engineering Contradiction:
Improvefreezing protectionVSAvoidheat efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The heater element is shaped to form a loop that conforms to the specific geometry of each port opening, providing localized heating precisely where needed rather than heating the entire housing. This targeted approach reduces wasted heat while maintaining effective freezing protection at the port surfaces.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The heater element transitions from a conventional planar heating configuration to a three-dimensional loop structure that wraps around port openings. This dimensional change allows the heater to follow the contours of the ports and directs heat more efficiently to the critical areas prone to freezing.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Temperature

If conventional heater assemblies are used, then heating function is provided, but device complexity and assembly difficulty increase

Engineering Contradiction:
Improveheating functionVSAvoidassembly complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The heater assembly is divided into modular sections, with each heater element loop corresponding to a specific port opening. This segmentation allows for independent fabrication and assembly of each heating zone, simplifying the overall assembly process and reducing complexity compared to integrated heating systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heater element design serves multiple functions: it provides heating, conforms to port geometry, and can be adapted to different port configurations. This multi-functionality reduces the need for additional components and simplifies the overall assembly structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If heaters are provided on assemblies subject to movement and vibration, then freezing protection is maintained, but durability deteriorates due to damage susceptibility

Engineering Contradiction:
Improvefreezing protectionVSAvoiddurability
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The heater element is constructed as a flexible loop that can accommodate movement and vibration without rigid structural constraints. This flexibility allows the heater to withstand mechanical stresses from aircraft operations while maintaining its heating function and protecting ports from freezing.

Inventive Principle:
Principle #30Flexible shells and thin films
