Spring-Loaded Diffuser Fastening for Reflector Screen Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diffusers for reflector screens often obstruct the light exit opening, leading to heat buildup and non-uniform lighting due to inadequate tensioning and difficult attachment/removal processes.
Innovation Solution
The diffuser features spring-loaded, flat plate fastening elements with eccentrically positioned openings to accommodate umbrella spokes, allowing for even tensioning and easy handling, ensuring the diffuser is positioned at a distance from the light exit opening and securely attached without direct contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If diffusers are detachably attached using conventional fastening means (Velcro, buttons), then the diffuser can be exchanged and removed, but the light exit opening is closed off leading to heat buildup and the diffuser folds due to lack of tension
Solution Approach 1:
The fastening system is segmented into multiple individual spring elements (5) distributed around the diffuser element's circumference, each independently accommodating a screen spoke (4). This segmentation allows localized attachment points that maintain tension without blocking the entire light exit opening, enabling heat circulation while preserving detachability.
Solution Approach 2:
The spring elements (5) provide dynamic, elastic attachment that automatically tensions the diffuser element (2) when attached to the reflector screen (1). The spring mechanism maintains constant tension force, preventing folding while allowing easy attachment and removal. The dynamic nature of the spring connection enables the diffuser to adapt to slight variations in screen spoke positioning.
2Ease of operation
If conventional fastening means are used, then attachment is possible, but the attachment and removal process becomes more difficult and tensioning is insufficient
Solution Approach 1:
The spring elements (5) are designed to automatically tension the diffuser element (2) upon attachment to the screen spokes (4). The spring mechanism self-adjusts to provide uniform tensioning force across all attachment points without requiring manual adjustment. This self-tensioning feature ensures reliable, wrinkle-free attachment while maintaining ease of operation - the user simply attaches the diffuser and the springs automatically provide the necessary tension.
3Strength
If the diffuser is positioned close to the light exit opening for secure attachment, then attachment strength is improved, but heat circulation is blocked reducing operational life
Solution Approach 1:
The spring elements (5) extend radially outward from the diffuser element's attachment perimeter, creating a dimensional extension that allows the diffuser to be positioned at an optimal distance from the light exit opening. This radial extension provides sufficient attachment leverage and strength while maintaining clearance for heat circulation between the diffuser and the light source, thereby preserving the service life of the reflector screen and lamps.
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
This design enhances the operational life and uniformity of lighting by allowing heat circulation and easy handling, preventing wrinkles and ensuring secure attachment, thus improving the performance and usability of reflector screens.
Implementation Method 1
the fastening elements are designed as one-piece elements that apply a spring effect
Implementation Method 2
the diffusers, which are arranged in the area of a light exit opening of the reflector screen, serve in particular to scatter the light
