Portable Lamp Rotating Lighting Device for Stability and Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable lamps have limited adaptability and stability due to fixed light radiation directions, which restrict their usage and effectiveness, especially when used outdoors where wind or vibrations can cause instability.
Innovation Solution
A portable lamp design featuring adjustable lighting devices that can rotate 360° relative to the handle body, allowing independent adjustment of their position and angle to optimize light radiation direction, ensuring flexible use and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the portable lamp is unfolded to a parallel position for light emission, then the lighting effectiveness is improved, but the stability deteriorates due to poor balance and susceptibility to wind and vibration
Solution Approach 1:
The patent applies the dynamics principle by enabling the lighting portions to rotate independently relative to the lamp body. This allows the lighting devices to dynamically adjust their orientation and positioning during use, optimizing both lighting effectiveness and stability based on operational conditions rather than being fixed in a parallel unfolded configuration
2Stability of the object's composition
If the portable lamp is unfolded in a V-shape for stability, then the stability is improved, but the lighting effectiveness deteriorates due to limited light radiation direction
Solution Approach 1:
The lighting portions are designed to rotate independently, allowing them to dynamically adjust their orientation even when the lamp body maintains a stable V-shape configuration. This resolves the contradiction by decoupling the stability function (maintained by the V-shape structure) from the lighting function (optimized through rotational adjustment of lighting portions)
Solution Approach 2:
The patent segments the lighting portions from the lamp body, allowing independent rotation and positioning of each lighting device. This segmentation enables the lamp body to maintain a stable V-shape while the lighting portions can independently orient themselves for optimal light radiation in multiple directions
3Device complexity
If the lighting portions are fixed on the lamp body, then the device complexity is reduced, but the adaptability deteriorates due to inability to adjust light radiation direction
Solution Approach 1:
The patent introduces rotational joints that allow lighting portions to rotate independently relative to the lamp body. This dynamic capability provides adaptability for adjusting light radiation direction without significantly increasing overall device complexity, as the rotational mechanism is integrated into the existing structure
Solution Approach 2:
The rotational adjustment mechanism is merged with the existing lamp structure, combining the stability of a fixed structure with the flexibility of adjustable lighting portions. The rotation mechanism is integrated rather than added as a separate complex subsystem

AI summary
A portable lamp includes at least one lighting device and at least one handle body. The at least one handle body has two end portions and a turning space defined between the two end portions. The at least one lighting device is rotatably mounted between the two end portions of the at least one handle body. The at least one lighting device is selectively arranged to be maintained in the turning space of the at least one handle body as a folded state and rotated with the at least one handle body to have an included angle between the at least one lighting body and the at least one handle body as an unfolded state. The portable lamp can adjust the state of the at least one lighting device without moving the at least one handle body.
