Molded Mesh Buffer Concealing Hazard Detector Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hazard detectors, such as smoke and carbon monoxide detectors, have visible internal components due to apertures for air and sound passage, compromising their aesthetic appeal and functionality.
Innovation Solution
A breathable, three-dimensionally molded mesh is integrated between the chassis and grille of the detector, conforming to the contoured surface, providing a uniform appearance while allowing air and sound permeability, and securing the mesh using flexible tabs and adhesive, ensuring acoustic and fluid flow properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If apertures are provided in the detector casing for air and sound passage, then air permeability and sound transmission are improved, but internal components become visible compromising aesthetic appearance
Solution Approach 1:
A mesh buffer element with controlled porosity is positioned between the chassis and grille. The mesh allows air molecules to pass through while blocking the view of internal components, achieving both air permeability and aesthetic concealment simultaneously
Solution Approach 2:
The mesh buffer element serves as an intermediary component between the chassis and grille. It mediates the conflict by providing a visual barrier while maintaining acoustic and airflow transmission, resolving the contradiction between aesthetics and functionality

3Shape
If a mesh buffer element is added between chassis and grille, then aesthetic appearance and component concealment are improved, but device complexity increases
Solution Approach 1:
The mesh buffer element is a simple, inexpensive component that can be easily manufactured and replaced. Despite adding a component, the overall complexity increase is minimal because the mesh is a passive element requiring no active control or complex integration
Solution Approach 2:
A mesh buffer element with controlled porosity is positioned between the chassis and grille. The mesh allows air molecules to pass through while blocking the view of internal components, achieving both air permeability and aesthetic concealment simultaneously

Implementation Method 1
aligning an adhesive backing of a mesh with a front surface of the chassis
Implementation Method 2
applying heat and pressure to the mesh to mold the mesh to conform to a three dimensional shape
Implementation Method 3
applying heat and pressure to the mesh to mold the mesh to conform to a three dimensional shape
Implementation Method 4
The molded mesh may define a mesh central aperture corresponding to the chassis central aperture
Implementation Method 5
The hazard detector may also include a grille secured to the chassis. The grille may define a grille central aperture corresponding to the chassis central aperture and further defining a plurality of openings positioned along a body of the grille

AI summary
A hazard detector includes a chassis configured to house components of the hazard detector. The chassis includes a front defining a central aperture. The front has a domed contour such that an outer edge of an inner portion extends beyond an outer periphery of the front. The inner surface tapers from the outer edge toward the inner portion. The detector includes a mesh formed to the contour of the front so the mesh is flat against the front. The mesh defines an aperture corresponding to the central aperture. The detector includes a grille secured to the chassis that defines an aperture corresponding to the central aperture and defines openings positioned along the grille. An inner surface of the grille includes a contour corresponding to the contour of the front so the mesh is flat against the inner surface. The mesh is positioned between the grille and the chassis.
