Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional helmets lack a structure to emit signals with lighting and brightness, limiting their attention drawing capability and accident prevention functionality, thus reducing their practicality.
Innovation Solution
A warning signal device integrated into a helmet with a light-pervious head housing, a soft wiring light source structure, a battery case, and a power switch, allowing for adjustable lighting, color, and flashing time, enhancing visibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional helmet with a smooth cap member is used, then the helmet structure is simple and easy to manufacture, but the attention drawing capability is insufficient and accident prevention function is not provided
Solution Approach 1:
The patent combines the warning signal device with the helmet structure by integrating the light-pervious head housing into the helmet shell and positioning the soft wiring light source structure within the helmet interior. This merging allows the helmet to simultaneously maintain its protective function and gain accident prevention capability through visible light signals.
Solution Approach 2:
The helmet is transformed from a single-function protective device to a multi-functional device that combines protection with active warning capability. The light source structure, when activated, enables the helmet to serve both as protective gear and as an attention-drawing warning device, particularly beneficial for workers in low-visibility environments.
2Reliability
If a light source structure is added to the helmet, then the attention drawing capability is improved, but the device complexity increases
Solution Approach 1:
The patent employs a soft wiring light source structure that utilizes flexible printed circuit boards to mount multiple light sources. This flexible substrate allows the light sources to be conformally arranged on the curved interior surface of the helmet, achieving uniform light distribution while maintaining a compact and integrated design that does not significantly increase overall device complexity.
Solution Approach 2:
The light-pervious head housing is designed with a curved surface that matches the helmet's geometry, and the soft wiring light source structure is configured to follow this curvature. This curved arrangement ensures uniform light emission across the helmet surface while maintaining aesthetic appearance and structural integration.
