Solution Overview

Problem

Existing ceiling speaker systems either lack the ease of installation of lay-in speakers or the aesthetic appeal of tile-mounted speakers, with no solution combining both benefits.

Innovation Solution

A support frame and back box assembly configured for installation on top of a ceiling tile, allowing for the mounting of a removable loudspeaker cartridge through a hole in the tile, with interchangeable cartridges and a design that accommodates multiple installations, including a fire-resistant back box for compliance with building codes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a speaker is mounted directly to a ceiling tile, then the installation is simple, but the speaker size is limited due to the tile's limited structural strength

Engineering Contradiction:
Improveease of installationVSAvoidstructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The system divides the mounting structure into separate components: a support frame that attaches to the ceiling tile and a back box that provides additional structural support. This segmentation allows the tile to remain intact while the support frame and back box bear the speaker's weight, enabling larger speakers to be installed without compromising the tile's structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support frame acts as an intermediary between the ceiling tile and the speaker, distributing the load across the tile's surface through the frame's geometry. The back box serves as a second intermediary, providing additional structural support and mounting surface. This intermediary structure eliminates the need to rely on the tile's inherent structural strength while maintaining simple installation procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If a support frame is added to support a heavier speaker, then the speaker weight capacity increases, but the installation complexity increases

Engineering Contradiction:
Improveweight capacityVSAvoidinstallation complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The support frame and back box are designed to work together as an integrated assembly. The support frame attaches to the ceiling tile grid, and the back box mounts to the support frame, creating a unified structure that supports the speaker. This merging of components streamlines the installation process compared to using separate support structures, as the frame and box are designed to fit together precisely and require minimal alignment adjustments.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support frame is designed to accommodate various speaker sizes and configurations, making it a universal mounting solution. The back box serves multiple functions: providing structural support, enclosing the speaker's rear components, and offering a mounting surface for electrical connections. This multi-functionality reduces the number of separate components needed, thereby simplifying installation while maintaining high weight capacity.

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

3Reliability

If a metal back can is added for fire code compliance, then fire safety compliance is achieved, but the device complexity increases

Engineering Contradiction:
Improvefire code complianceVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fire-resistant back box is integrated with the structural support function. The same back box that provides mounting surface and structural support also serves as the fire containment enclosure. This merging of fire safety function with structural and mounting functions eliminates the need for separate fire containment structures, thereby maintaining device simplicity while achieving fire code compliance.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If a lay-in speaker design is used, then the installation is easy, but the visual appearance is compromised

Engineering Contradiction:
Improveease of installationVSAvoidvisual appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The system separates the installation structure (support frame and back box) from the visible speaker assembly. The support frame attaches to the ceiling tile grid, while the speaker is mounted within the back box, which is positioned to be flush with or slightly recessed in the ceiling tile. This segmentation allows the visible portion to maintain the clean appearance of a traditional tile-mounted speaker while the hidden support structures provide the ease of installation characteristic of lay-in speakers.

Inventive Principle:
Principle #1Segmentation
