Solution Overview

Problem

Interior building materials with integrated light-emitting panels face challenges in maintenance and replacement due to the fixed structure, which hinders the detachment and replacement of the light source, leading to inefficiencies in decorative presentation and longevity.

Innovation Solution

A mounting structure that allows the planar light-emitting panel to be directly or indirectly attachable and detachable from a mounting member, with a decorative member covering the emission surface, enabling easy maintenance and replacement while providing a high decorative presentation effect through pattern changes with lighting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the light source is integrated into the translucent decorative material in a fixed structure, then the decorative presentation is improved, but the light source cannot be detached for maintenance or replacement

Engineering Contradiction:
Improvedecorative presentationVSAvoidmaintenance of light source
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The invention divides the interior building material into separate functional modules: a mounting member fixed to the wall, a planar light-emitting panel that can be detached, and a decorative member. This segmentation allows the light-emitting panel to be independently replaced for maintenance while preserving the decorative structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces a dynamic attachment system where the planar light-emitting panel can be attached to and detached from the mounting member. This dynamic connection enables easy maintenance and replacement of the light source while maintaining a stable fixed installation on the wall surface.

Inventive Principle:
Principle #15Dynamics

2Ease of repair

If the planar light-emitting panel is made detachable from the mounting member, then maintenance and replacement become easy, but the structural complexity increases

Engineering Contradiction:
Improvereplacement of light-emitting panelVSAvoidmounting structure
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The mounting structure is segmented into distinct functional components: a mounting member for wall attachment, a planar light-emitting panel for illumination, and a decorative member for aesthetic presentation. This clear segmentation simplifies the overall structure while enabling easy assembly and disassembly for maintenance.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the decorative member covers the emission surface of the planar light-emitting panel, then the decorative presentation effect is enhanced, but the light transmission is reduced

Engineering Contradiction:
Improvedecorative presentation effectVSAvoidlight transmission
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The decorative member is designed with spatially varying optical properties, featuring different patterns for non-lighting and lighting states. This local quality variation allows the decorative member to selectively transmit light in specific patterns while maintaining overall decorative coverage, thus enhancing the decorative presentation effect without completely blocking light transmission.

Inventive Principle:
Principle #3Local quality

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

Facilitates easy replacement and maintenance of the light-emitting panel, enhancing the decorative presentation and design properties by allowing the light-emitting panel to be detached and reattached, while ensuring a high decorative effect and efficient power supply to the panels.

Implementation Method 1

a planar light-emitting panel interposed between the mounting member and the decorative member, wherein the planar light-emitting panel is directly or indirectly attachable to and detachable from the mounting member with capability of supplying power from the mounting member side

Methodology Applied
Scientific EffectLight emission: Light Emitting Diode

Implementation Method 2

during lighting, the decorative member transmits a part of emitted light from the emission surface through the decorative member to express a second pattern different from the first pattern

Methodology Applied
Scientific EffectLight transmission: Refraction

AI summary

Provided is an interior building material having a high decorative presentation effect and an easy replacing capability of an organic EL panel. An organic EL panel is interposed between a mounting member and a decorative member. The mounting member is fixed to a wall surface of a fixed structure. The organic EL panel is directly or indirectly attachable to and detachable from the mounting member with power supply capability from a side of the mounting member. The decorative member covers an emission surface of the organic EL panel with presentation of a first pattern during non-lighting and with expression of a second pattern different from the first pattern during lighting.
