Flexible Removable Headlamp Shade for Lantern Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlamp shades are often non-flexible and inconvenient to carry, especially in outdoor activities like camping or hiking where space and weight are concerns, and they do not easily convert the headlamp into a lantern configuration.
Innovation Solution
A removable shade made from flexible, translucent polypropylene material with interlocking panels and notches that allow the headlamp to be easily attached and detached, enabling the headlamp to be converted into a lantern and easily packed when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a non-flexible housing is used for the headlamp shade, then the structural strength and stability are improved, but the ease of carrying and packing space are worsened
Solution Approach 1:
The patent applies this principle by using a flexible shade material that can be collapsed into a compact form for carrying, yet maintains its functional shape when attached to the headlamp. The flexible material allows the shade to conform to the headlamp housing while providing the necessary light diffusion and shading functions.
Solution Approach 2:
The shade transitions from a static, rigid structure to a dynamic, adaptable form. When not in use, the shade collapses into a compact configuration for easy storage. When attached to the headlamp, it expands and conforms to the housing shape, providing structural stability and functional performance.
2Stability of the object's composition
If a rigid shade structure is used, then the stability and light diffusion quality are improved, but the adaptability and ease of packing are worsened
Solution Approach 1:
The flexible shade material provides structural stability when mounted on the headlamp housing while maintaining the ability to collapse into a compact form for storage. The material's flexibility allows it to adapt to different headlamp shapes and sizes.
Solution Approach 2:
The shade is designed as a removable accessory that can be separated from the headlamp housing. This segmentation allows the shade to be independently packed in a compact form while maintaining its functional integrity when attached to the headlamp.
3Adaptability or versatility
If a removable shade design is used, then the versatility and ease of storage are improved, but the device complexity and attachment mechanisms are worsened
Solution Approach 1:
The shade is designed as a separate, removable component that can be independently attached to or removed from the headlamp housing. This segmentation provides versatility for different lighting conditions and easy storage, while the attachment mechanism is kept simple through the use of flexible material that can be easily secured to the housing contours.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a lightweight, compact, and versatile shade that allows for adjustable lighting effects and easy conversion of a headlamp into a lantern, while minimizing space and weight, making it suitable for outdoor activities.
Implementation Method 1
The removable shade is preferably made from a light diffusing, sturdy yet flexible material such as polypropylene

AI summary
A shade for removable attachment to a headlamp assembly having a headlamp connected to a head-strap where the shade is formed from first and second flexible, translucent wall panels which may lay flat against each other when not in use. The shade includes notches formed in each wall panel to which the segments of the head-strap located on either side of the headlamp may be removably connected. The headlamp assembly and shade when connected together may be suspended from a fixed point or placed upon a flat surface thereby creating a hands-free lantern.
