Emergency Light Status Visibility via Segmented Housing Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency lights with integrated status displays for battery charge state, when installed in a wall or ceiling, obscure the visibility of the light source indicating the battery state due to the display device covering the lamp housing, making the status light invisible to the observer.
Innovation Solution
Incorporating a light exit opening in the lamp housing frame allows the light emitted by the status light source to project outward, ensuring visibility outside the housing, with the light source positioned at a distance from the exit opening to reduce susceptibility to failure and facilitate installation, and optionally featuring a holding device with a positioning knob for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display device completely covers the lamp housing, then the aesthetic appearance is improved, but the visibility of the status light becomes impossible
Solution Approach 1:
The housing frame is segmented to include a light exit opening that allows the status light to be visible while maintaining the overall aesthetic appearance. The display device covers most of the housing but leaves a specific segment (light exit opening) exposed for status indication.
Solution Approach 2:
The housing frame has different local qualities: most areas are covered by the display device for aesthetics, while the light exit opening area remains exposed to allow status light visibility. This local differentiation resolves the contradiction between aesthetic appearance and status visibility.
2Volume of stationary object
If the light source is positioned close to the housing wall, then the installation space is reduced, but the light source becomes susceptible to external influences and installation difficulties
Solution Approach 1:
The light source is positioned in a different spatial dimension relative to the housing wall - specifically, at a distance from the wall rather than directly adjacent to it. This dimensional separation reduces susceptibility to external influences while maintaining compact overall installation.
3Volume of moving object
If the light source is positioned close to the housing wall, then the overall device size is reduced, but the installation precision becomes difficult to achieve
Solution Approach 1:
A holding device with a positioning knob acts as an intermediary between the light source and the housing wall. This intermediary component facilitates precise positioning and alignment of the light source at the required distance from the wall, making installation precise while maintaining compact device size.
4Reliability
If the light source is positioned away from the housing wall, then the susceptibility to external influences is reduced, but the device complexity increases
Solution Approach 1:
The holding device with positioning knob enables the light source to be self-positioned and secured at the correct distance from the housing wall. This self-service mechanism reduces susceptibility to external influences while adding minimal complexity, as the positioning system is integrated into the installation process itself.
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
The solution ensures the status light is visible to the observer, enhances stability by maintaining a small gap between the display device and the wall, and simplifies installation while reducing the risk of light source failure from external influences.
Implementation Method 1
a light source (5) for displaying the state of charge of batteries or accumulators (10; 20) located in the light housing (1), which are suitable for supplying the light sources (3; 5) of the display device (3) in an emergency, wherein the illuminant is arranged within the lamp housing (1), and wherein a light exit opening (4) is provided in the housing frame (2) and the illuminant of the light exit opening (4) so is assigned that the light emitted by the bulb passes through the light exit opening (4) and projects a light cone on the wall so that it is visible outside the lamp housing

AI summary
The processing apparatus (1) has a movable holding unit (3) that is arranged relatively to the housing (2). The shaping blank and processing tool (5) are connected with the holding unit. The processing tool is arranged to supply liquid such as water, in a processing area of the shaping blank. The processing area is separated from the housing by partially surrounding the processing area with a cover unit (6).
