Solution Overview

Problem

Existing light reflectors with non-circular light sources face challenges in achieving uniform light distribution due to the complexity and cost of producing diffusers, and they often experience noise issues from loose fastening due to heat effects.

Innovation Solution

A light reflector design featuring a translucent separating disk firmly attached using material deformation embossings, allowing for cost-effective production and noiseless operation, with a manufacturing process that connects multiple reflector jacket pieces for customizable light distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separating disk is attached using additional fastening means, then the separating disk is securely fixed, but the production becomes complicated and expensive

Engineering Contradiction:
Improvesecure fixing of separating diskVSAvoidproduction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The attachment embossings are formed directly on the reflector jacket surface, merging the fastening function into the existing structure. The reflector jacket itself serves as both the structural component and the fastening mechanism, eliminating the need for separate fastening elements and simplifying production.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The reflector jacket performs the fastening function autonomously through its own surface deformations. The material of the reflector jacket is deformed to create attachment embossings that directly secure the separating disk, allowing the component to serve its own fastening needs without external assistance.

Inventive Principle:
Principle #25Self-service

2Ease of manufacture

If the separating disk is loosely fastened, then the production is simpler, but disturbing noises arise during operation due to heat effects

Engineering Contradiction:
Improveproduction simplicityVSAvoidnoise from loose fastening
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The attachment embossings are formed in advance during the production process, creating pre-compression contact between the reflector jacket and the separating disk. This preliminary securing prevents the disk from loosening under subsequent thermal expansion and contraction during operation, cushioning against future noise problems.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The physical state of the reflector jacket material is changed through localized deformation to create permanent attachment points. The material undergoes plastic deformation to form embossings that mechanically interlock with the separating disk, changing from a smooth surface to a textured fastening surface.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple jacket pieces are used to form the reflector, then the light distribution can be customized, but the production complexity increases

Engineering Contradiction:
Improveconfigurable light distributionVSAvoidmulti-part assembly
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment embossing technique serves multiple functions: it secures the separating disk, connects multiple jacket pieces, and positions components accurately. This universal fastening method works for various assembly configurations, making the multi-part construction manageable despite its complexity.

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

Solution Approach 2:

The reflector jacket is divided into multiple detachable pieces that can be assembled separately and then connected through attachment embossings. This segmentation allows for customized light distribution profiles while maintaining production efficiency through modular manufacturing and assembly.

Inventive Principle:
Principle #1Segmentation

AI summary

The light reflector (1) has reflector casing whose interior portion is defined with light-permeable partition plate, to separate several reflector chambers (101,102). The plate is fixedly secured on the reflector casing by integrally formed attachment embossments (11). The reflector casing is produced by pressing process or injection molding process or deep-drawing process. The reflector casing is made of metal or light metal sheet, and also partially made of thermoplastically deformable plastic. Independent claims are included for the following: (1) lamp with bulb and light reflector; and (2) method for manufacturing light reflector.
