Solution Overview
Problem
High-quality vacuum cleaner nozzles with rotatably driven brush rollers face challenges in optimizing the limited installation space for both functional lighting and aesthetic design, particularly in providing efficient and energy-saving lighting solutions that enhance the visual appeal without compromising on cleaning functionality.
Innovation Solution
The integration of decorative lighting using a light source and a light-guiding distributor within the nozzle's housing, where the light is distributed through a transparent material to create a diffuse glow effect, allowing for both decorative and functional lighting with a single light source, optimizing space and energy usage, and potentially using a rotating brush roller-driven air turbine to generate power for the lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single light source is used for both decorative lighting and functional illumination, then space utilization is improved and device complexity is reduced, but the light distribution control becomes more difficult and aesthetic quality may be compromised
Solution Approach 1:
The housing is divided into different functional zones with distinct lighting requirements. The light-guiding distributor segments the light from a single source into decorative portions (guiding light along the housing contour) and functional portions (illuminating the working area), allowing one light source to serve multiple purposes effectively
Solution Approach 2:
A light-guiding distributor acts as an intermediary element between the single light source and the various lighting zones. This mediator component directs and distributes light appropriately to different areas, enabling both decorative and functional lighting requirements to be met simultaneously
2Shape
If decorative lighting is added to enhance aesthetic appeal, then visual design is improved, but energy consumption increases
Solution Approach 1:
The decorative lighting function is merged with the functional illumination requirement. A single light source serves dual purposes: providing necessary working area illumination while simultaneously creating decorative visual effects through the light-guiding distributor, thereby avoiding additional energy consumption
Solution Approach 2:
The lighting system is designed with multi-functionality, where one light source performs multiple functions including both decorative illumination (enhancing aesthetic appeal) and functional illumination (providing working area lighting), eliminating the need for separate lighting systems
3Illumination intensity
If multiple lighting functions are provided separately, then lighting quality for each function is optimized, but installation space requirement increases
Solution Approach 1:
The lighting system is designed with multi-functionality, where one light source performs multiple functions including both decorative illumination (enhancing aesthetic appeal) and functional illumination (providing working area lighting), eliminating the need for separate lighting systems
Solution Approach 2:
The decorative lighting function is merged with the functional illumination requirement. A single light source serves dual purposes: providing necessary working area illumination while simultaneously creating decorative visual effects through the light-guiding distributor, thereby avoiding additional energy consumption
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
This configuration enhances the aesthetic appeal of the nozzle while efficiently utilizing space and energy, providing effective decorative and functional lighting without increasing material costs or production complexity, and allows for self-sufficient power generation from the suction air flow.
Implementation Method 1
the distributor is at least partially transparent internally, allowing the coupled light to propagate within at least a portion of its volume
Implementation Method 2
the coupling area is designed such that at least a subset of the coupled light can exit at the surface of the light-guiding distributor. To the observer, this creates the effect that the coupling area appears to emit light
