Solution Overview

Problem

Existing recessed ceiling lights designed to form a line of light often face challenges in maintaining precise alignment during installation due to the susceptibility of their side walls to bending, especially when intended for curved ceiling areas, leading to inaccurate attachment.

Innovation Solution

A luminaire with an elongate housing featuring a socket element that stabilizes the edge area, allowing for precise alignment through a snap-in connection and flexible design to accommodate curved surfaces, while maintaining the edge area's linear alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the housing is designed to be bendable for curved ceiling installations, then adaptability to curved surfaces is improved, but alignment precision of the edge area deteriorates

Engineering Contradiction:
Improveadaptability to curved surfacesVSAvoidalignment precision of edge area
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The housing is divided into multiple side wall segments that can be independently bent, allowing the housing to adapt to curved ceiling surfaces while maintaining precise alignment through the socket element that stabilizes each segment's edge area

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The socket element acts as an intermediary between the bendable housing and the installation opening, providing stabilization and alignment of the edge area while allowing the housing to maintain its flexibility for curved surfaces

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the side walls are made flexible for curved installations, then ease of installation is improved, but stability of the edge area deteriorates

Engineering Contradiction:
Improveease of installationVSAvoidstability of edge area
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The socket element serves as a mediator that provides stabilization to the flexible edge area of the housing, enabling easy installation in curved surfaces while maintaining the stability needed for precise alignment during mounting
