Sensor Lid Reflector Units for Homogeneous Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing status displays for sensors require significant construction space and suffer from light loss due to the use of pucks, which homogeneously emit light in all directions, making it inefficient to illuminate only specific areas.
Innovation Solution
A lid with a basic body having a covering surface and side wall, featuring a first and second reflector unit arranged oppositely to reflect light emitted by a lighting means onto a light-transmissive light emitting region, allowing for efficient and homogeneous illumination of desired areas without the need for pucks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a puck is used to reflect and distribute light homogeneously, then the light distribution becomes uniform, but the construction space increases and light output is lost
Solution Approach 1:
The single puck is segmented into two separate reflector units (first and second reflector units) positioned at different locations. Each reflector unit independently directs light to specific regions, achieving homogeneous overall illumination while reducing the volume required compared to a single large puck.
Solution Approach 2:
Instead of using a single volumetric puck, the solution transitions to a planar arrangement with reflector units positioned at opposite sides of the lid. This dimensional change from a three-dimensional puck to a two-dimensional distributed reflector system reduces construction space while maintaining light distribution effectiveness.
2Illumination intensity
If a puck is used to homogenously emit light in all directions, then light distribution is uniform, but light output is lost and specific area illumination becomes inefficient
Solution Approach 1:
Each reflector unit is designed to direct light to specific local regions of the lid rather than distributing light uniformly in all directions. The first reflector unit illuminates its corresponding light-emitting region while the second reflector unit illuminates its opposite region, reducing unnecessary light loss while achieving homogeneous overall illumination.
3Illumination intensity
If a puck is used for status display illumination, then the display is visible, but the device complexity and construction space increase
Solution Approach 1:
The reflector units are integrated directly into the lid structure itself, merging the illumination function with the housing structure. This eliminates the need for separate puck components and reduces overall device complexity while maintaining effective status display illumination.

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 provides a space-saving and efficient illumination of the status display, enhancing visibility of the sensor status even under bright conditions, while minimizing light loss and allowing flexibility with different lighting means.
Implementation Method 1
the light emitted by the lighting means (16) is reflected to the at least one light emitting region (36) by means of the first reflector unit (30) and the second reflector unit (32)
