Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stage lights with brake motors often require an external power source to unlock and reset controlled components after power failure, leading to inefficient packing and maintenance due to locked states.
Innovation Solution
A stage light with an unlockable brake motor featuring a motor unit, braking unit, controller, auxiliary power source, and input unit, allowing manual resetting without external power, using a magnetic attraction braking mechanism and boost circuit for convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a brake motor is used to lock the controlled component after power off, then the controlled component is prevented from falling down and being damaged, but the controlled component cannot be manually moved or rotated for packing and maintenance
Solution Approach 1:
The auxiliary power source is integrated into the stage light system itself, eliminating the need for external power sources. The system serves itself by using its own auxiliary power source to unlock the brake motor when needed for packing or maintenance, making the system self-sufficient and easier to operate.
Solution Approach 2:
The brake motor's locking state is made dynamic rather than static. By using the auxiliary power source to temporarily power the brake motor, the controlled component can switch between locked and unlocked states as needed, enabling manual movement for packing while maintaining protection during normal operation.
2Stability of the object's composition
If the controlled component is locked in position after power off, then the controlled component maintains its original position, but the stage light cannot be efficiently packed or stored
Solution Approach 1:
The brake motor is activated periodically rather than continuously. It locks the controlled component during normal operation, then is temporarily deactivated using the auxiliary power source when packing is needed, and reactivated afterward. This periodic action maintains both stability and packing efficiency.
3Ease of operation
If an external power source is required to unlock the brake motor, then the controlled component can be reset, but the operation becomes complicated and time-consuming
Solution Approach 1:
The auxiliary power source and brake motor are merged into a single integrated system within the stage light. This combination eliminates the need for separate external power sources and complex wiring, simplifying the unlocking operation to merely pressing a button on the existing control panel.

AI summary
The present invention discloses a stage light having an unlockable brake motor, comprising a controlled component, and a braking motor (200) that drives the controlled component to move, wherein the braking motor comprises a motor unit (210) and a braking unit (220) for braking the motor unit (210), and the braking motor is a power-off locking motor; and further comprising a controller (300), an auxiliary power source (400) that supplies backup power to the braking unit (220), and an input unit (410) that controls on and off of the auxiliary power source (400), wherein the motor unit (210) and the braking unit (220) are connected in parallel with each other and are both electrically connected to the controller (300). The braking motor (200) locks the motor unit (210) after the stage light is powered off, so that the controlled component is kept in an original position, thereby preventing the controlled component from falling down and being damaged; and after the stage light is detached, the auxiliary power source (400) may be controlled by means of the input unit (410) to power the braking unit, thereby implementing the unlocking of the controlled component. In this way, for both the packing of the stage light and maintenance due to power-off, the controlled component may be freely moved or rotated, which is very convenient.
