Adjustable Suspended Lighting Fixtures Angular Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suspended lighting fixtures lack the ability to adjust the angle and orientation of lower supports relative to the ground, limiting user flexibility in configuration and aesthetics.
Innovation Solution
The use of adjustable suspension cables attached to rotatable members allows for the angular adjustment of lower supports, enabling them to be fixedly maintained at various angles without user intervention, with the cables also capable of transmitting electrical power to light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed suspension cords are used, then the structure is simple and stable, but the angular configuration of lower supports cannot be adjusted
Solution Approach 1:
The patent applies the Dynamics principle by replacing fixed suspension cords with adjustable suspension cables that can be repositioned along rotatable members. This allows the lower supports to be dynamically adjusted to various angular configurations while maintaining structural stability. The cables can be moved to different positions on the rotatable members to change the angular orientation of the lower supports relative to the ground.
Solution Approach 2:
The patent implements Another dimension (Dimensionality change) by introducing rotatable members that add rotational freedom to the suspension system. The upper cord support includes rotatable members that can rotate about axes, enabling the suspension cables to be positioned not only at different heights but also at different angular orientations, thereby adding a rotational dimension to the previously fixed linear suspension.
2Ease of operation
If adjustable suspension cables with rotatable members are used, then angular configuration flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent applies Universality (Multi-functionality) by designing the suspension cables to serve multiple functions: they provide structural support, enable angular adjustment, and transmit electrical power to the light sources. The rotatable members also serve dual purposes as both adjustment mechanisms and cable support structures, reducing the need for separate components.
Solution Approach 2:
The patent implements Merging (Combining) by integrating the suspension and power transmission functions into a single cable system. The suspension cables are configured to both mechanically support the lower supports and electrically power the light sources, eliminating the need for separate power conduits and reducing overall system complexity.
3Adaptability or versatility
If multiple cords are used for suspension, then stability is improved, but the ability to independently adjust angles of multiple lower supports is limited
Solution Approach 1:
The patent applies Segmentation by providing independent rotatable members for each lower support, allowing each support to be adjusted independently to different angular configurations. Each suspension cable is associated with its own rotatable member, enabling individual adjustment without affecting other supports.
Solution Approach 2:
The patent implements Dynamics by enabling independent dynamic adjustment of multiple lower supports through separate rotatable members. Each lower support can be repositioned to different angular orientations as needed, providing flexible configuration options for multi-support fixtures while maintaining operational simplicity.

AI summary
A fixture such as a light fixture includes, for example, a first lower support, and a first cord and a second cord for suspending the first lower support. Lower portions of the first and second cords are attachable to the first lower support. An upper cord support is attachable to upper portions of the first and second cords. The upper cord support is operable to fixedly position the upper portions of the first and second cords over a range of different positions so that the first lower support is fixedly maintainable at different angles relative to the ground. A fixture may include a second lower support and the upper cord support may be operable to independently fixedly position the upper portions of the third and fourth cords over a range of different positions so that the second lower support is fixedly maintainable at different angles relative to the ground.
