Recessed Lighting Orientation Adjustment via External Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recessed outdoor lighting apparatuses with sealed optics compartments require professional intervention to change light beam orientation, exposing internal components to pollutants and leading to malfunctions due to atmospheric exposure.
Innovation Solution
A lighting apparatus with external actuation means allowing users to adjust the orientation of the light beam without opening the sealed compartment, using a system of rotating supports and knobs to manipulate the optics from outside, ensuring the compartment remains sealed and protected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optics compartment is opened to adjust the orientation of the light beam, then the orientation can be changed, but the internal components are exposed to pollutants and moisture causing degradation
Solution Approach 1:
The patent introduces an intermediary mechanism (actuating means with shafts and knobs) that transmits rotational motion from the external environment to the internal optics without requiring direct access to the sealed compartment. This mediator allows orientation adjustment while maintaining the seal integrity, preventing pollutant and moisture ingress.
Solution Approach 2:
The apparatus is segmented into a sealed optics compartment and an external actuation mechanism. The actuation mechanism operates independently outside the sealed compartment, allowing users to adjust orientation without compromising the sealed environment that protects sensitive internal components.
2Reliability
If professional installers adjust the optics orientation in a controlled environment, then the components are protected from contamination, but the adjustment process requires specialized personnel and controlled conditions
Solution Approach 1:
The patent enables end-users to perform orientation adjustments themselves through externally accessible actuating means (knobs and shafts). This self-service capability eliminates the need for professional installers and controlled environments, while the sealed compartment continues to protect components from contamination.
Solution Approach 2:
The external actuating mechanism serves as an intermediary that bridges the gap between user accessibility and component protection. Users can easily operate the knobs from outside the sealed compartment, and this intermediary mechanism translates their actions into precise orientation adjustments without requiring them to open the sealed compartment.
3Adaptability or versatility
If the sealed compartment is opened for orientation changes, then the light beam direction can be modified, but the sealing is compromised leading to oxidation and corrosion
Solution Approach 1:
The system is divided into a sealed compartment housing the optics and an external actuation system. This segmentation allows the compartment to remain continuously sealed for component protection, while the external actuation system provides the necessary orientation adjustment capability without compromising the seal.
Solution Approach 2:
The actuating means (knobs, shafts, and coupling mechanisms) act as an intermediary that enables orientation changes without breaking the seal. The mechanism transmits rotational input from the external environment to the internal optics through the sealed barrier, maintaining sealing integrity while providing orientation flexibility.
