Solution Overview

Problem

Current acoustic panel systems are limited in their ability to quickly and easily switch between different acoustic modes (absorbing, reflecting, and diffusing) without affecting the original design of a space and require manual labor to reconfigure, which is time-consuming and laborious.

Innovation Solution

A device with a movable back plate and front panel system that allows for three acoustic modes - absorbing, reflecting, and diffusing - by adjusting the position of acoustic elements through apertures, which can be controlled wirelessly, allowing for quick changes in acoustic properties without manual object movement and maintaining the space's original design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If movable acoustic elements are added or removed from a space to change acoustic properties, then the acoustic settings can be modified for different events, but the process requires manpower and is time-consuming

Engineering Contradiction:
Improveacoustic settings modificationVSAvoidtime to reconfigure
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies the dynamics principle by making the acoustic panel itself movable rather than stationary. The panel can be automatically positioned at different locations within the space (ceiling, walls, or floor) to change acoustic properties. This automated dynamic positioning eliminates the need for manual movement of multiple separate acoustic elements, thereby reducing both time and labor while maintaining adaptability for different acoustic settings.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple separate acoustic elements are introduced to increase absorbing properties or add reflective/diffusing properties, then the acoustic properties can be enhanced, but the process is laborious and time-consuming due to fastening requirements

Engineering Contradiction:
Improveacoustic property enhancementVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent merges multiple acoustic functions (absorption, reflection, diffusion) into a single integrated acoustic panel. This unified panel contains all necessary acoustic elements in one structure, eliminating the need to install and fasten multiple separate components. The merged design simplifies installation while providing comprehensive acoustic property enhancement across different modes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The acoustic panel is designed with multi-functionality to perform multiple acoustic roles simultaneously. The panel can operate in different modes (absorption, reflection, diffusion) by adjusting its position and orientation, making it a universal acoustic solution that replaces multiple specialized elements. This universality reduces installation complexity while maintaining the ability to enhance various acoustic properties.

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

3Adaptability or versatility

If acoustic elements are added or removed to change acoustic settings, then the acoustic properties can be modified, but the original design of the space may be affected negatively

Engineering Contradiction:
Improveacoustic settings adjustmentVSAvoidoriginal design integrity
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent uses a movable acoustic panel that can be positioned at different locations (ceiling, walls, or floor) to create equivalent acoustic effects without permanently altering the space's original design. The panel acts as a temporary, repositionable element that copies or replicates the acoustic functions of fixed elements, allowing acoustic settings adjustment while preserving the integrity of the original architectural design.

Inventive Principle:
Principle #26Copying
