Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light stands require manual adjustment of light source position, leading to slow and inefficient illumination direction changes.
Innovation Solution
A light stand equipped with a first driving mechanism that rotates the support frame relative to the base, and a second driving mechanism that rotates the light source component, enabling automatic adjustment of illumination direction and angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual adjustment is used for light source position, then the structure is simple, but the adjustment speed is slow and timeliness is poor
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated driving mechanism. The driving mechanism includes a driving motor, transmission components (such as gear racks and pinions), and control systems that automatically adjust the light source position and illumination direction, eliminating the need for manual operation while achieving rapid and precise positioning.
Solution Approach 2:
The light stand is equipped with sensors and control systems that enable it to automatically detect and adjust its own position and orientation. The system can self-adjust the light source position and illumination angle based on preset parameters or real-time feedback, making the device self-sufficient without requiring external manual intervention.
2Loss of time
If manual adjustment is used for light source position, then the device is simple to operate, but the timeliness of illumination direction change is poor
Solution Approach 1:
The patent replaces manual adjustment operations with an automated driving mechanism controlled by electrical signals. The control system receives commands and automatically actuates the driving motors to adjust the light source position and illumination direction, dramatically reducing the time required for direction changes while transferring operational complexity from the user to the automated system.
Solution Approach 2:
The light stand incorporates sensors and detection devices that provide real-time feedback on the current position and orientation of the light source. The control system uses this feedback to continuously monitor and adjust the illumination direction, ensuring rapid response to directional changes while maintaining precise positioning through closed-loop control.
3Productivity
If automatic adjustment mechanism is added, then adjustment speed improves, but device complexity increases
Solution Approach 1:
The patent divides the adjustment system into separate functional modules: a driving mechanism for position adjustment, a second driving mechanism for illumination direction adjustment, and supporting structures. Each module operates independently but coordinates with others, allowing the system to achieve high adjustment efficiency while managing complexity through modular design and functional separation.
Data Source
AI summary
This present disclosure pertains to the domain of lighting fixtures, particularly a light stand. The light stand includes a light stand base furnished with a first driving mechanism, as well as a support frame designed for the installation of a light source component. The output terminal of the first driving mechanism is linked to the underside of the support frame, facilitating its ability to rotate the support frame relative to the light stand base, and thus rotate the light source component. By integrating the first driving mechanism into the light stand base and connecting its output terminal to the bottom of the support frame, the mechanism effectively rotates the support frame, subsequently rotating the light source. This design fulfills the objective of automatically adjusting the light source component's position.
