Solution Overview

Problem

Ceiling-mounted speakers have a uniform appearance that does not blend with ceiling surface patterns, limiting design options for architects and interior designers.

Innovation Solution

A printable sound diffuser with magnetically attachable components that can be customized to match ceiling patterns, featuring a steel ring and disc cover plate with printable surfaces and rare earth magnets for alignment with ceiling designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional ceiling speakers with uniform frames and grills are used, then manufacturing simplicity and ease of installation are maintained, but aesthetic versatility and ability to match ceiling patterns are limited

Engineering Contradiction:
Improveaesthetic versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ceiling speaker system is divided into separate components: a fixed frame, a removable grill, and a printable diffuser overlay. This segmentation allows each component to be optimized independently - the frame provides structural support, the grill enables speaker replacement, and the diffuser provides aesthetic customization without increasing overall system complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The diffuser uses printed patterns that copy or replicate ceiling surface patterns (such as acoustic tile patterns) to create visual blending. This allows the speaker to match various ceiling designs without requiring custom manufacturing for each pattern, maintaining ease of production while achieving aesthetic versatility

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If magnetic attachment components are added for pattern alignment, then aesthetic integration with ceiling patterns is improved, but manufacturing complexity and component quantity increase

Engineering Contradiction:
Improvepattern alignment capabilityVSAvoidease of manufacture
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The magnetic attachment system enables self-alignment of the diffuser with the ceiling pattern through manual rotation. The magnets provide the attachment force while allowing the user to independently position and align the pattern, eliminating the need for complex alignment mechanisms or specialized installation tools

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The diffuser incorporates printed patterns with varying colors and designs that can match different ceiling patterns. This visual customization approach achieves aesthetic integration without requiring physical customization of the component structure, maintaining ease of manufacture through standard printing processes

Inventive Principle:
Principle #32Color changes

3Adaptability or versatility

If printable surfaces are incorporated on steel components, then aesthetic customization capability is improved, but manufacturing complexity and material requirements increase

Engineering Contradiction:
Improvecustomization capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The steel ring and disc cover plate serve multiple functions: they provide structural support, magnetic attachment surfaces, and printable aesthetic surfaces. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in device complexity while achieving customization capability

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

AI summary

A sound diffuser for a ceiling speaker system having a downward-facing (when installed) flat disc cover plate and a flat barrel flange that assists in clamping a ceiling tile. The downward facing surfaces of the disc cover plate and a flat ring releasably attached to, and covering, the barrel flange are printable surfaces. The ring and the disc are magnetically attractable and are held in place with magnets. The ring and the disc cover plate can be rotated to align patterns printed on the ring and the disc cover plate to align to a pattern on the ceiling and to each other. Three-dimensional printing of the ring and/or the disc cover plate is included. The diffuser is preferably used in conjunction with the SMALL CEILING SPEAKER SYSTEM of US patent application serial number 15/710,654, the entire contents of which are incorporated herein by reference.
