Solution Overview

Problem

Existing acoustic panels with lighting systems face challenges due to non-uniform dimensions of mounting grooves, requiring multiple profiles for different widths, leading to increased tooling, warehousing, and logistics costs, as well as complex planning.

Innovation Solution

A diffuser profile with outwardly curved profile legs and retaining elements allows secure clamping in varying groove widths, eliminating the need for additional profiles and reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple profiles with different widths are used to accommodate varying groove widths, then secure fixation in all groove types is achieved, but tooling, warehousing, and logistics costs increase significantly

Engineering Contradiction:
Improvefixation securityVSAvoidprofile variety
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The diffuser profile is designed with a universal structure that can accommodate multiple groove widths through its adjustable profile legs. The profile legs can be positioned at different distances from each other, allowing the same profile to fit into grooves of varying widths, thus eliminating the need for multiple specialized profiles.

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

Solution Approach 2:

The profile legs are designed to be movable and adjustable rather than fixed. This dynamic capability allows the installer to adapt the profile leg spacing to match the specific groove width, providing a flexible solution that maintains secure fixation across different installation scenarios without requiring multiple static profile types.

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple profiles with different widths are used to accommodate varying groove widths, then secure fixation in all groove types is achieved, but planning complexity increases significantly

Engineering Contradiction:
Improvefixation securityVSAvoidplanning simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The universal profile design simplifies planning by providing a single standardized component that can be used across all installation scenarios. Planners no longer need to calculate and order multiple profile types based on groove width variations, reducing planning complexity while maintaining fixation security through adjustable profile leg positioning.

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

3Device complexity

If a single diffuser profile is used in varying groove widths, then tooling and logistics costs are reduced, but secure fixation becomes challenging

Engineering Contradiction:
Improveprofile varietyVSAvoidfixation security
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The profile legs are pre-configured with retaining elements that engage with the groove walls. Before final installation, the profile legs can be preliminarily positioned and adjusted to the appropriate spacing, ensuring that when the diffuser profile is inserted, secure fixation is automatically achieved without requiring additional fastening operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The adjustable profile legs provide dynamic adaptation capability, allowing the single profile type to maintain secure fixation across varying groove widths. The profile legs can be positioned and secured at different spacings, ensuring reliable engagement with groove walls regardless of the specific groove width encountered.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution enables cost-effective installation in differently sized grooves, reducing tooling and logistics costs while ensuring secure fixation, thus simplifying planning and enhancing sustainability.

Implementation Method 1

The profile legs are at least partially curved outwards and have retaining elements on their outer surface designed to clamp the diffuser profile within a receiving groove of the acoustic panel. The outward (convex) curvatures of the profile legs allow the diffuser profile to be clamped to a certain extent in receiving grooves of varying widths.
