Flexible Composite Headband Headlamp to Reduce Forehead Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable headlamps have suboptimal comfort and weight distribution due to rigid housings cantilevered from the forehead, causing pressure points and inefficient weight support.
Innovation Solution
A composite structure integrating flexible and rigid components, with flexible support members adhered to a rigid housing, forming a streamlined and balanced headlamp that distributes weight more evenly and reduces pressure points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If rigid housings are cantilevered out from the user's forehead, then the light emitting element, battery power supply, and control electrics can be contained, but comfort and weight distribution deteriorate causing pressure points
Solution Approach 1:
The patent merges the rigid housing with the flexible headband by integrating the housing directly into the headband structure, eliminating the need for separate cantilevered housings. This integration distributes weight more evenly across the headband, reducing pressure points while maintaining structural support for the light emitting element and battery power supply.
Solution Approach 2:
The patent employs a composite structure combining rigid housing materials with flexible headband materials. This composite construction allows the housing to provide structural support for the electrics while the flexible material provides comfort and weight distribution, resolving the contradiction between structural integrity and comfort.
2Strength
If rigid housings are used to contain components, then structural support is provided, but weight distribution becomes unbalanced and pressure points are caused
Solution Approach 1:
The patent applies local quality by using rigid materials only where structural support is needed (in the housing containing the electrics) and flexible materials where comfort and weight distribution are needed (in the headband). This localized material selection provides structural support where required while eliminating pressure points through the flexible portions that conform to the user's head.
3Stress or pressure
If the housing is broken into two separate housings, then weight distribution improves, but the rigid housings are still attached to rather than integrated inside the flexible band, resulting in poor weight support
Solution Approach 1:
The patent merges the previously separate housings into a single integrated housing structure that is directly integrated inside the flexible headband. This integration improves weight support by distributing the weight of the electrics and battery power supply across the entire headband structure rather than having separate attached housings, while maintaining balanced weight distribution.
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 composite structure enhances comfort and weight distribution, making the headlamp less noticeable and preventing snagging on objects, while maintaining a secure fit.
Implementation Method 1
The flexible material can be impregnated or coated with an adhesive that can allow the layers of fabric to be joined by application of heat and/or pressure to form the composite structure.

AI summary
This disclosure provides a portable lamp worn on the head and method of construction for the portable lamp. The construction method forms a composite structure that improves the comfort, reduces the volume, and better distributes the weight of the components of the lamp. The method of construction allows for a flexible material or set of flexible materials to be used to encapsulate the rigid parts of the headlamp. The flexible and rigid materials can be joined together in a heat press process that results in a single composite structure that has both attributes of the rigid material(s) and the flexible material(s) in different areas of the lamp. The battery can be located at the back or otherwise remote from the light to improve weight distribution and comfort for the user.
