Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid display technologies fail to create dynamic and selectable light effects in laminar or low turbulent liquid streams, limiting their ability to display stationary or moving patterns effectively.
Innovation Solution
The method involves generating a laminar or low turbulent liquid stream with adjustable liquid parameters and synchronized light and light deflecting means, using light packets and particles or bubbles introduced into the stream to create cinematographic effects through Sequential Pulse Modulation (SPM), allowing for the display of various patterns based on environmental and user-defined settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light sources are located outside the liquid stream (external illumination), then the device complexity is reduced, but the illumination intensity and visual effect are insufficient
Solution Approach 1:
The light source is nested within the liquid stream itself, with the liquid acting as both the medium and the light guide. The light emitter is positioned inside the liquid flow path, allowing light to propagate through the liquid from the interior, creating enhanced visibility and visual effects without requiring external illumination structures.
2Illumination intensity
If laminar flow is maintained to create glass-like jet effects, then the light guidance is improved, but the light visibility to onlooker is reduced
Solution Approach 1:
The system introduces periodic disturbances to the laminar flow using thumpers or scratchers that locally and temporarily disrupt the flow at regular intervals. This periodic action allows light to escape from the stream at controlled points, making the light visible to onlookers while maintaining overall laminar flow stability for light guidance.
Solution Approach 2:
The continuous laminar flow is segmented by introducing localized disturbances at specific points along the stream. These segmentations create discrete light escape points through which light becomes visible, while the rest of the stream maintains its laminar structure for effective light guidance.
3Illumination intensity
If stream interrupters or thumpers are introduced to enhance light visibility, then the light visibility is improved, but the manufacturing precision and flow control become more difficult
Solution Approach 1:
The thumpers or scratchers are designed to be passive elements that rely on the kinetic energy of the liquid stream itself to operate. The flow velocity and pressure naturally drive these disturbance elements, eliminating the need for external power sources or complex control mechanisms, thereby maintaining manufacturing precision while enhancing light visibility.
4Illumination intensity
If additive water streams are introduced to create ripple effects, then the light radiation is enhanced, but the device complexity and control difficulty increase
Solution Approach 1:
The additive water stream system is merged with the main liquid stream at the outlet, where the additive stream and main stream combine to create the desired ripple effects. This integration reduces the need for separate control systems and simplifies the overall device complexity while maintaining enhanced light radiation capabilities.
