Solution Overview
Problem
Conventional headlamps have not evolved significantly in terms of their headbands, which remain elastic and lack ergonomic, aesthetic, and functional advancements, failing to meet the diverse needs of users and offering limited adjustment possibilities.
Innovation Solution
A headlamp with a rigid/semi-rigid headband featuring alternating sections allowing deformation in multiple planes, providing a constant length and wide adjustment capabilities, integrated electrical wiring, and additional functionalities such as battery fixation and rear signaling, along with a pivot for adjustable light beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an elastic headband is used to ensure proper holding of the headlamp, then the headlamp is securely held on the user's head, but the headband lacks ergonomic, aesthetic, and functional advancements and offers limited adjustment possibilities
Solution Approach 1:
The headband is divided into multiple rigid or semi-rigid sections that can be independently adjusted. Each section can be positioned to accommodate different head shapes and sizes, providing extensive adaptability while maintaining a relatively simple overall structure through modular segmentation.
Solution Approach 2:
The headband incorporates adjustable mechanisms that allow dynamic reconfiguration of the rigid sections. This enables the headband to adapt to different users and head sizes while maintaining structural integrity, resolving the contradiction between adaptability and structural simplicity.
2Ease of operation
If a conventional elastic headband is used, then the headlamp is properly held on the user's head, but it fails to meet diverse user needs and offers limited ergonomic and aesthetic advancements
Solution Approach 1:
Different sections of the headband have different properties - some sections are rigid for structural support and adjustability, while others may be more flexible for comfort. This local differentiation enhances ergonomic comfort without requiring complete redesign of the entire headband structure.
Solution Approach 2:
The headband is designed to serve multiple functions: holding the headlamp securely, providing ergonomic comfort, offering aesthetic appeal, and accommodating diverse head sizes. The rigid/semi-rigid sectional design enables this multi-functionality while maintaining manageable complexity.
3Adaptability or versatility
If the headband is designed with wide adjustment capabilities for different head sizes, then it can accommodate various users, but the structural complexity increases
Solution Approach 1:
By segmenting the headband into standardized rigid or semi-rigid sections, the design achieves wide adjustment capability through simple reconfiguration of existing modules rather than custom manufacturing for each size, thereby maintaining ease of production.
Solution Approach 2:
The headband accommodates different head sizes by changing the configuration parameters of the rigid sections (position, angle, spacing) rather than changing the fundamental structure or materials, allowing versatile adjustment while keeping manufacturing processes simple and consistent.

AI summary
A headlamp is disclosed with a lamp fitted with a light source; a headband allowing the fastening of the headlamp over the head of a user, where the headband has a constant length, symmetrical with respect to a median sagittal plane. The headband also has an alternation of rigid/semi rigid elements for allowing a deformation in the space and the adjustment on the user's head is presented. In addition, the headband has a rigid/semi-rigid front section allowing a certain deformability along a first plane (x, y), a rigid/semi-rigid intermediate section allowing a certain deformability along a second plane (x, z) and a rigid/semi-rigid rear section allowing a certain deformability along a third plane (y, z). The headband has elements for the attachment and the passage of an elastic link for constraining the deformation of the rigid/semi rigid headband within the three planes.
