Portable Neck Light With Elastic-Pad Rotating Light Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neck lights do not provide hands-free illumination with adjustable and secure positioning for workers in low-light conditions, limiting their effectiveness and usability.
Innovation Solution
A portable neck light with a neck band and pivotally coupled light heads that allow continuous rotation and secure positioning through an elastic pad and shaft mechanism, enabling hands-free illumination with adjustable light direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light head is fixed to the neck band, then the structure is simple and stable, but the light direction cannot be adjusted
Solution Approach 1:
The light head is made movable relative to the neck band through a pivot joint mechanism, allowing it to rotate and adjust its direction dynamically while maintaining structural stability when positioned
2Adaptability or versatility
If the light head can rotate freely, then the light direction is highly adjustable, but the positioning stability deteriorates
Solution Approach 1:
The elastic pad automatically engages with the shaft to provide friction-based positioning, allowing the light head to be held securely at any rotated position without external intervention or complex locking mechanisms
3Stability of the object's composition
If a locking mechanism is added to secure the light head position, then positioning stability improves, but the device complexity increases
Solution Approach 1:
The elastic pad provides automatic friction-based positioning that self-adjusts to hold the light head at any rotated position, eliminating the need for additional locking mechanisms while maintaining positioning stability
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 neck light provides secure, hands-free illumination with adjustable light direction, enhancing usability and flexibility for workers in low-light environments.
Implementation Method 1
an inner surface of the third opening is configured to engage an outer surface of the shaft to apply a radial holding force on the shaft support the light head in a plurality of positions with respect to the neck band

AI summary
A portable neck light includes a neck band having an arm extending to a distal end, the distal end defining a rotation axis. A light head is coupled to the distal end of the arm. A shaft is coupled to the light head and the neck band to allow rotation of the light head relative to the neck band about the rotation axis within a rotation plane. The light head is supported for continuous movement within an angular range of motion about the rotation axis.
