Remote Light Fixture Adjustment With Motorized Pan, Tilt, and Spot Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio-visual lighting systems require manual adjustment of light fixtures, which is time-consuming and unsafe due to the need for repeated climbing and lowering of fixtures to achieve desired lighting conditions.
Innovation Solution
A remote light adjustment apparatus comprising a main body, extending arm, and remote body with motors for pan, tilt, and spot control, allowing for wireless operation and secure mounting to external structures, enabling remote control of lighting fixtures from the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of light fixtures is performed by climbing ladders or lowering fixtures, then lighting adjustments can be made, but safety risks increase and time consumption increases
Solution Approach 1:
The patent replaces manual mechanical adjustment (climbing ladders, physically moving fixtures) with an automated motorized system. Motors drive pan and tilt mechanisms to position light fixtures remotely, eliminating the need for operators to climb towers or manually lower fixtures. This mechanical substitution resolves the contradiction by maintaining adjustment capability while removing safety risks associated with manual high-altitude operations.
Solution Approach 2:
The patent introduces a remote control system as an intermediary between the operator and the light fixture. The control unit communicates wirelessly with the motorized fixture, allowing the operator to remain on the ground while the fixture is positioned remotely. This intermediary mechanism enables lighting adjustments without direct physical interaction at height, resolving the safety contradiction.
2Ease of operation
If manual adjustment of light fixtures is performed by climbing ladders or lowering fixtures, then lighting adjustments can be made, but time consumption increases
Solution Approach 1:
The automated motorized system replaces time-consuming manual operations. Instead of repeatedly climbing ladders or physically moving heavy fixtures to adjust positioning, the motorized pan and tilt mechanisms rapidly reposition fixtures electronically. This substitution dramatically reduces the time required for lighting adjustments while maintaining full operational capability.
Solution Approach 2:
The system allows for preliminary positioning and adjustment to be made remotely before final setup. Operators can pre-position multiple fixtures from the ground using the remote control system, then make fine adjustments without time-consuming climbs. This preliminary action through the intermediary control system reduces overall setup time.
3Productivity
If remote control capability is added to light fixtures, then operational safety and efficiency improve, but device complexity increases
Solution Approach 1:
The patent employs universal mounting apparatus that can accommodate various light fixture types and tower configurations. The motorized pan and tilt mechanisms are designed with standardized interfaces and control protocols that work across different fixture models. This universality allows the system to handle multiple functions (different fixture types, mounting positions, adjustment ranges) without proportionally increasing complexity, resolving the contradiction between productivity improvement and device complexity.
