Headlamp Lighting Device with Dual Support and Rotating Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headlamps often suffer from instability due to gravity-induced torque on a single mounting point, leading to sagging or detachment of the light source, and reliance on a single type of battery that may not be readily available in remote locations.
Innovation Solution
A headlamp design featuring a base with two support members and a rotating body that adjusts the light source's angle, combined with a versatile battery pack that can accommodate various battery types and voltages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single mounting point is used to support the light source, then the device complexity is reduced, but the reliability deteriorates due to gravity-induced torque causing sagging or detachment
Solution Approach 1:
The mounting structure is segmented into multiple support members (at least two) distributed across the base member, rather than relying on a single mounting point. This segmentation distributes the gravitational torque across multiple attachment points, preventing sagging and detachment while maintaining reasonable structural complexity.
2Device complexity
If a single type of battery is used, then the device complexity is reduced, but the adaptability deteriorates because replacement batteries may not be available in remote locations
Solution Approach 1:
The power source is designed with universality by incorporating a battery compartment that can accommodate multiple battery types (e.g., AA, AAA, C, D batteries) and voltage configurations. This allows the headlamp to function with various battery types, ensuring adaptability in remote locations where specific battery types may not be available, while maintaining a unified and simple power source interface.

AI summary
Various lighting devices are provided which may be used to advantageously illuminate areas of interest in a secure, convenient manner. In one example, a lighting device includes a headlamp. The headlamp includes a base, a body, and a light source. The base includes two support members and an aperture in each of the support members. The body is secured to the base through the apertures and is adapted to rotate relative to the base. The light source is in the body and positioned substantially between the two support members. The light source is adapted to rotate with the body relative to the base to adjust an angle of light emitted by the light source. As another example, related methods are also provided.
