Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable lighting equipment lacks efficient control systems for operation, deployment, and runtime management, particularly in terms of battery power and environmental conditions, leading to suboptimal performance and user experience.
Innovation Solution
A portable lighting tower with an electronically-controlled system that includes a frame, adjustable mast, multiple legs with actuators, a controller, and a battery pack, which allows for dimming, deployment, and leveling based on user input and environmental conditions, using a tilt sensor to adjust leg deployment and a user interface for real-time monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the lighting tower uses battery power with extended runtime capability, then the duration of action is improved, but the weight of the battery pack increases
Solution Approach 1:
The battery system is divided into multiple modular battery packs that can be independently attached to different portions of the lighting tower structure. This allows the runtime to be extended by adding more battery modules while distributing the weight across multiple locations, making the system more manageable and adaptable to different runtime requirements.
2Ease of operation
If the lighting tower includes electronically-controlled actuators for automatic deployment and leveling, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The lighting tower incorporates self-leveling capabilities through electronically-controlled actuators that automatically adjust the tower's position and orientation. The system uses sensors to detect the tower's state and autonomously makes adjustments to maintain proper leveling, reducing the need for manual intervention and simplifying operation despite the added complexity of the control system.
3Adaptability or versatility
If the lighting tower provides dimmable light output with multiple intensity settings, then the adaptability to different environmental conditions is improved, but the device complexity increases
Solution Approach 1:
The lighting system incorporates dimmable LEDs with electronically-controlled intensity adjustment capabilities. The controller system dynamically adjusts the light output based on environmental conditions, user preferences, and battery status, providing adaptability to various operating scenarios. This dynamic control allows the system to optimize performance while managing power consumption effectively.
4Ease of operation
If the lighting tower uses electronically-controlled actuators instead of manual deployment, then the ease of operation is improved, but the use of energy increases
Solution Approach 1:
The electronically-controlled actuators are designed to operate in periodic cycles rather than continuously. The system activates the actuators only when deployment or adjustment is needed, then enters a low-power state. This periodic operation significantly reduces overall energy consumption while maintaining the ease of automatic deployment capability when required.

AI summary
A portable lighting tower includes a frame, an adjustable mast, multiple legs, a controller, and a battery pack. The adjustable mast is coupled to the frame and includes a light. The multiple legs each include an actuator operable to deploy and retract the respective leg. The controller is operatively coupled to the light and the actuators and configured to control operation of the light and the actuators. The battery pack is electrically coupled to the controller, the light, and the actuators. The light is dimmable between a maximum setting and a minimum setting, and the controller operates each of the linear actuators to deploy or retract the respective leg response to a user input.
