Rotatable Outdoor Speaker Tower with Rotation Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor sound systems lack directional sound delivery and integrated lighting solutions for enhanced ambiance, often resulting in tangled wires and inadequate terrain illumination.
Innovation Solution
A combination speaker and lighting tower, or bollard, featuring a rotatable speaker unit with a stop to prevent full 360-degree rotation and integrated illumination devices for directional sound and terrain lighting, anchored to a base that can be mounted on a flat surface or embedded in the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the speaker unit is made rotatable to provide directional sound delivery, then sound directionality is improved, but wire tangling occurs due to excessive rotation
Solution Approach 1:
A stop mechanism is built into the rotatable speaker unit to prevent it from rotating more than necessary. This preliminary constraint stops the rotation before wires become tangled, allowing directional sound control while avoiding the harmful effect of wire tangling
2Illumination intensity
If outdoor sound systems are designed without integrated lighting, then device complexity is reduced, but terrain illumination and ambiance are insufficient
Solution Approach 1:
The patent combines a speaker system with a lighting tower into a single integrated outdoor unit. The lighting tower includes multiple illumination devices that can be positioned at different heights and angles to provide both terrain illumination and ambient lighting, while the speaker system provides directional sound delivery
Solution Approach 2:
The integrated bollard serves multiple functions simultaneously: it provides directional sound delivery through the rotatable speaker unit, terrain illumination through downward-facing lights, ambient lighting through upward-facing lights, and structural stability through its tower design with base and ground stake
3Adaptability or versatility
If the illumination devices are positioned to provide both terrain and ambient lighting, then versatility of lighting coverage is improved, but device complexity increases
Solution Approach 1:
The lighting tower is segmented into multiple illumination devices positioned at different locations and orientations. One device is positioned to illuminate terrain downward, while another is positioned to provide ambient lighting upward, allowing versatile lighting coverage without requiring a single complex adjustable device

AI summary
A combination speaker and lighting tower for use outdoors. The lighting tower has a base and a housing that includes at least one lamp. A rotatable coupler is used to mount a speaker unit on the tower, which allows the speaker unit to rotate in a horizontal plane. A stop is provided in the coupler to prevent the speaker unit from rotating a full 360 degrees. The speaker unit may be fixed to a specific location or allowed to oscillate back and forth. The lighting tower may be installed on a patio or anchored in the ground.
