Solution Overview

Problem

Radiant ceiling panel systems suffer from significant heat loss and sound reflection issues due to side wall elements, which are difficult to retrofit and comply with structural and material standards, and existing thermal decoupling methods are costly and impractical.

Innovation Solution

Applying a thermally insulating and sound-absorbing coating to the side wall sections facing away from the tube register, allowing the coating to be open and exposed, which reduces lateral heat loss and sound reflection without requiring extensive structural changes, and allowing existing systems to be retrofitted efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If side wall elements are provided to enclose the tube register, then structural stability and protection are improved, but heat loss through convection increases and sound reflection worsens

Engineering Contradiction:
Improvestructural stabilityVSAvoidheat loss
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The side wall elements are designed with a porous structure that allows controlled air flow through the walls rather than creating hard reflections. This porous design reduces sound reflection while maintaining structural integrity and minimizing convective heat loss by allowing gradual pressure equalization.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The side wall elements combine multiple materials with different properties - structural materials for stability, insulating materials for heat reduction, and acoustic-absorbing materials for sound management. This composite approach resolves the contradiction by integrating multiple functions into a single component system.

Inventive Principle:
Principle #40Composite materials

2Loss of energy

If thermal decoupling of side parts is implemented, then heat loss is reduced, but manufacturing complexity and cost increase

Engineering Contradiction:
Improveheat lossVSAvoidmanufacturing complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The side wall elements integrate thermal insulation, acoustic absorption, and structural support functions into a single unified component rather than using separate decoupling elements. This merging approach reduces heat loss while avoiding the manufacturing complexity of multiple discrete thermal decoupling parts.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The side wall elements are designed as multi-functional components that simultaneously provide structural stability, thermal insulation, and acoustic absorption. This universal design eliminates the need for separate thermal decoupling mechanisms, reducing both heat loss and manufacturing complexity.

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

3Reliability

If side wall elements completely enclose the tube register, then protection is improved, but sound reflection increases

Engineering Contradiction:
ImproveprotectionVSAvoidsound reflection
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The side wall elements utilize porous materials that absorb sound waves rather than reflecting them, while still providing complete enclosure and protection for the tube register. The porous structure allows sound energy to be dissipated through the material matrix rather than being reflected back into the room.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The acoustic properties of the side wall elements are optimized by changing material parameters such as porosity, density, and thickness to achieve sound absorption while maintaining protective enclosure functions. This parameter optimization allows complete protection without harmful sound reflection.

Inventive Principle:
Principle #35Parameter changes
