Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting fixtures lack the ability to redirect light effectively without occupying excessive space, as most are fixed or require manual adjustment and have limited mechanized motion.
Innovation Solution
A rotatable lighting fixture with a mobile housing and stationary housing, featuring a connection rod and two rotation mechanisms that allow the light source and lens to be positioned in various orientations, enabling wide-range motion without occupying large volumes, using magnetic interactions and motors for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lighting fixtures are made fixed, then installation is simple and structure is stable, but the ability to redirect light is lost
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed lighting fixture into a movable one. The fixture incorporates a motorized rotation mechanism that enables automatic redirection of light without manual intervention. The housing can rotate about a vertical axis and the lens can rotate about a horizontal axis, allowing dynamic adjustment of light direction controlled by a user interface or automation system.
2Ease of operation
If mechanized adjustment systems are added to lighting fixtures, then ease of operation improves, but device complexity and volume increase
Solution Approach 1:
The patent applies segmentation by dividing the rotation mechanism into two independent parts: a first rotation mechanism for rotating the housing about a vertical axis, and a second rotation mechanism for rotating the lens about a horizontal axis. This segmentation allows each mechanism to be simpler and more compact, reducing overall device complexity while maintaining full adjustability capability.
Solution Approach 2:
The patent applies the nested doll principle by placing the second rotation mechanism (lens rotation) inside the first rotation mechanism (housing rotation). The lens rotation assembly is nested within the housing structure, allowing both mechanisms to occupy overlapping spatial volumes and reducing the overall footprint of the mechanized adjustment system.
3Adaptability or versatility
If wide range of motion is achieved in lighting fixtures, then adaptability improves, but the volume occupied increases
Solution Approach 1:
The patent applies dimensionality change by implementing rotation about two different axes (vertical and horizontal) rather than attempting to achieve wide motion in a single plane. This multi-axis approach allows the fixture to redirect light across a broad three-dimensional space while keeping each individual rotation mechanism compact, as each mechanism only needs to handle rotation about one axis.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible and efficient redirection of light over a wide area without occupying excessive space, providing ease of installation and operation through dual-axis rotation mechanisms.
Implementation Method 1
The geared covering member may include an electromagnet or a permanent magnet. The mobile housing may include one or more of an electromagnet or a permanent magnet configured to interact with the geared covering member to cause rotation of the mobile housing about the second rotational axis.
Implementation Method 2
The geared covering member, the mobile housing, and the encasing member may include an electromagnet that may be configured to generate a sequential magnetic field. The sequential magnetic field may be sequenced to interact with an opposing magnet to cause rotation of the mobile housing about the second rotational axis.
Implementation Method 3
The encasing member may comprise a ferromagnetic member configured to interact with the geared covering member to cause rotation of the mobile housing about the second rotational axis.

AI summary
A lighting fixture comprising a stationary housing and a mobile housing carried by the stationary housing is provided. The lighting fixture also includes a lens carried by the mobile housing, a first rotation mechanism operatively connected to the connection rod, and a second rotation mechanism carried by the encasing member. The connection rod may protrude at least partially through the backing of the mobile housing. The first rotation mechanism may be configured to rotate the mobile housing about a first rotational axis, and the second rotation mechanism is configured to rotate the mobile housing about a second rotational axis. The mobile housing is configured to rotate about the first rotational axis such that portions of the lens are selectively positionable below a plane defined by a lower surface of the encasing member.
