Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjustable light fixtures face challenges in meeting specific standards for environments such as wet locations and air-tight ratings, while also requiring flexibility in installation and positioning, which existing technologies struggle to address effectively.
Innovation Solution
The design includes a housing with a cavity that allows for multiple positions of a body portion, utilizing a resilient device to maintain the body's position relative to the housing, and a sealing member to ensure environmental isolation, allowing for adjustable tilt and rotation while meeting regulatory standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light fixture is made adjustable to allow multiple positions and tilt angles, then the adaptability and ease of operation are improved, but the device complexity increases
Solution Approach 1:
The light fixture incorporates a dynamically adjustable body that can move between multiple positions and tilt angles within a housing. The body is configured to have multiple positions relative to the housing, including a tilt angle, allowing the fixture to adapt to different installation requirements while maintaining a relatively simple overall structure through controlled dynamic movement.
Solution Approach 2:
The light fixture is divided into distinct segments: a housing and a separate body portion that can move independently. The body is divided into first and second body portions that movably abut against each other, allowing independent adjustment of different sections to achieve multiple positions without complicating the entire fixture structure.
2Ease of operation
If the light fixture is made adjustable with multiple positions, then the ease of operation is improved, but the reliability in meeting environmental standards deteriorates
Solution Approach 1:
A resilient device acts as an intermediary between the movable body and the housing, maintaining continuous contact and pressure to ensure sealing surfaces remain engaged. The resilient device pushes the first body portion against the top portion of the housing and the second body portion against the bottom end, ensuring environmental standards are met regardless of the body's position.
Solution Approach 2:
The patent employs sealing members that can flex or deform to maintain contact with the housing walls across multiple body positions. These flexible sealing elements adapt to the varying positions of the adjustable body while maintaining environmental isolation, allowing ease of adjustment without compromising reliability.

AI summary
An adjustable light fixture can include a housing having at least one wall that forms a first cavity, wherein in the housing has a top portion and a bottom end. The fixture can also further include a body having a first body portion and a second body portion, where the body is movably disposed within the first cavity of the housing, where the body is configured to have a plurality of positions relative to the housing. The adjustable light fixture can also include a resilient device disposed between the first body portion and the second body portion to simultaneously push the first body portion against the top portion of the housing and the second body portion against the bottom end of the housing when the body is in each of the positions relative to the housing.
