Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display cases face issues with glare and uneven illumination due to localized light sources, which distract viewers and create non-uniformity in product displays, and some products are inadequately illuminated when located far from light sources.
Innovation Solution
A redemption counter or display case with a housing featuring translucent panels and a pattern of multicolor LEDs connected to a control unit, allowing for uniform color emission and adjustable lighting to enhance visibility and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light sources are positioned near the ends of shelves in display cases, then illumination intensity at the ends is improved, but uneven illumination and glare are created across the display
Solution Approach 1:
The display case is divided into multiple sections with individual lighting zones. Each shelf section can be illuminated independently, allowing the ends to receive enhanced illumination while the center maintains appropriate lighting levels, thus achieving both end illumination and overall uniformity through segmented lighting control
Solution Approach 2:
Different regions of the display case are provided with different lighting characteristics. The end regions receive higher illumination intensity through positioned light sources, while the center regions maintain moderate illumination, creating local quality variations that satisfy both end illumination requirements and overall display uniformity
2Illumination intensity
If light sources are positioned to illuminate specific areas, then localized illumination is improved, but glare and distraction are created for viewers
Solution Approach 1:
Diffusing panels or translucent materials are introduced as intermediaries between the light sources and the displayed items. These intermediaries soften and distribute the light, maintaining localized illumination intensity while reducing glare and harsh direct lighting that causes viewer distraction
Solution Approach 2:
The lighting system adjusts parameters such as color temperature, intensity, and beam angle to optimize illumination. By changing these parameters, the system provides sufficient localized illumination while minimizing glare effects that would distract viewers, achieving both illumination effectiveness and visual comfort
3Use of energy by moving object
If horizontal fluorescent tubes are used to light the interior, then energy efficiency is improved, but products far from the light source are inadequately illuminated
Solution Approach 1:
The lighting system transitions from purely horizontal fluorescent tube illumination to a multi-dimensional lighting arrangement that includes vertical lighting elements and angled positioning. This dimensional change allows light to reach products at various distances and positions within the display case, improving illumination coverage while maintaining energy efficiency through targeted lighting zones
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 provides a uniformly illuminated display with adjustable color options, reducing glare and enhancing the visibility of all products, while maintaining a visually appealing and consistent lighting effect across the display case.
Implementation Method 1
A pattern of multicolor LEDs is provided inside the housing behind this at least one translucent panel. The multicolor LEDs are connected to a control unit for controlling the color emitted by each multicolor LED.
Implementation Method 2
The control unit and the at least one translucent panel are adapted to impart a determined impression of color to the at least one panel. the pattern of multicolor LEDs is arranged such that a substantially uniform impression of color is imparted to the at least one translucent panel.
