Pivoting Light Module for Walking Stick Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional walking stick handles with fixed light-emitting modules cannot provide continuous illumination in the direction needed, requiring users to tilt the stick, which compromises its functionality and safety.
Innovation Solution
A walking stick handle structure with a pivotally connected light-emitting module, allowing adjustable illumination angles through a mechanism of recesses and bumps on the connection portion and handle body, enabling the light ray to be directed forward or downward for continuous illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light-emitting module is fixed at a specific angle to the handle body, then the structure is simple and stable, but the illumination direction cannot be adjusted, requiring the user to tilt the walking stick which compromises its functionality
Solution Approach 1:
The light-emitting module is changed from a fixed structure to a rotatable one, allowing the illumination direction to be dynamically adjusted. The connection portion with recesses and bumps enables the module to rotate to different angles (forward, downward, or intermediate positions) while maintaining stable engagement at each position, thus providing adaptability without excessive complexity.
2Ease of operation
If the light-emitting module is fixed in position, then the device complexity is low, but continuous illumination in the needed direction cannot be provided
Solution Approach 1:
The connection portion is designed with recesses that allow the light-emitting module to be rotated to different angles and locked in place. This dynamic adjustment mechanism enables the user to easily orient the light in the desired direction (forward for walking illumination, downward for ground illumination, or intermediate angles) while maintaining a relatively simple overall structure through the use of engagement features.

AI summary
A walking stick handle structure includes a handle body, a light-emitting module, and a power module. The handle body has two casings coupled together to form an opening. The casings each have an inner wall disposed thereon with a plurality of bumps corresponding in position to the opening. The light-emitting module has a first light-emitting portion and a connection portion. The connection portion is disposed in the opening and pivotally connected to the casings to enable the connection portion to rotate relative to the handle body. The connection portion has a curved surface and two lateral surfaces. The lateral surfaces each have recesses aligned in an arcuate pattern. The bumps are engaged with and fixed to the recesses, respectively, by an angle of rotation of the connection portion relative to the handle body. The power module is disposed in the handle body and electrically connected to the first light-emitting portion.
