Solution Overview

Problem

Existing lighting fixtures in suspended ceilings face challenges with acoustic jackets that require physical attachment, making installation, maintenance, and repair cumbersome and time-consuming, often damaging the fixture when removed.

Innovation Solution

An acoustic jacket device that can be installed over suspension cables without attaching to the lighting fixture, allowing easy access for maintenance and installation, using a folding and locking mechanism with PET Felt material and a computer program for precise cuts and scores.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the acoustic jacket is physically attached to the lighting fixture, then the acoustic coverage and noise reduction are improved, but the installation complexity and maintenance difficulty increase significantly

Engineering Contradiction:

Improvenoise reductionVSAvoidinstallation complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system separates the acoustic jacket from the lighting fixture, allowing the jacket to be independently suspended on cables while the fixture remains separate. This segmentation enables the jacket to provide acoustic coverage without being physically attached to the fixture, simplifying both installation and maintenance operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The suspension cable system acts as an intermediary between the acoustic jacket and the lighting fixture. The cable support structure enables the jacket to be positioned and secured in place without direct attachment to the fixture, resolving the contradiction between acoustic coverage and installation complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the acoustic jacket is physically attached to the lighting fixture, then the acoustic coverage is improved, but the maintenance time and fixture damage risk increase

Engineering Contradiction:

Improveacoustic coverageVSAvoidmaintenance ease

Core Design Contradiction:

Object-affected harmful factorsVSEase of repair

Solution Approach 1:

By separating the acoustic jacket from the lighting fixture through independent suspension systems, the jacket can be removed and reinstalled without affecting the fixture. This eliminates the need to damage or disassemble the fixture during maintenance, significantly improving ease of repair.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The acoustic jacket is extracted from the fixture assembly and suspended independently on separate cables. This extraction allows the jacket to be maintained, removed, or replaced without any impact on the lighting fixture, eliminating fixture damage risk during maintenance operations.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of repair

If the jacket device is removed from suspension cables for maintenance, then the lighting fixture access is improved, but the installation time and complexity increase

Engineering Contradiction:

Improvefixture accessVSAvoidinstallation time

Core Design Contradiction:

Ease of repairVSLoss of time

Solution Approach 1:

The independent suspension cable system for the jacket allows the fixture and jacket to be installed separately and independently. The fixture can be installed first on its own support structure, and the jacket can be subsequently suspended on separate cables, reducing total installation time and complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lighting fixture can be installed and positioned in advance on its support cables before the acoustic jacket is suspended. This preliminary installation of the fixture allows the jacket to be added later without requiring removal or repositioning of the fixture, reducing overall installation time.

Inventive Principle:

Principle #10Preliminary action

4Ease of repair

If separate cable systems are used for fixture and jacket, then the maintenance ease is improved, but the device complexity and cost increase

Engineering Contradiction:

Improvemaintenance easeVSAvoidsystem complexity

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The suspension cable system is designed to support both the lighting fixture and the acoustic jacket independently. The cables and support structure serve multiple functions: supporting the fixture, supporting the jacket, and enabling independent maintenance of either component, thereby reducing overall system complexity despite the separate suspension capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)
