Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of commercially available Center High Mounted Signal Lamp (CHIMSL) systems for two-wheeled vehicles, which are essential for enhancing visual warnings during braking to prevent rear-end collisions, as existing aftermarket devices are not aesthetically pleasing or interesting to use.
Innovation Solution
A helmet-based CHIMSL indicator system that uses a processor, accelerometer, and gyroscope to detect a decrease in vehicle velocity, activating an indicator lamp mounted on the helmet, with optional components like a smartphone for sensor data processing and wireless communication to ensure accurate braking signal detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a CHIMSL system is installed on a two-wheeled vehicle, then visual warning during braking is improved, but the device complexity increases due to lack of mounting structure
Solution Approach 1:
The patent moves the CHIMSL from a vehicle-mounted position to a helmet-mounted position, changing the spatial dimension of installation. This allows two-wheeled vehicles without high-mounted structures to achieve the same visual warning function by utilizing the rider's helmet as the mounting platform, thereby resolving the contradiction between improved illumination and device complexity.
2Measurement precision
If sensor-based braking detection is implemented, then braking event detection accuracy is improved, but the device complexity increases due to multiple sensors and processors
Solution Approach 1:
The patent uses the smartphone as an intermediary device that already contains the necessary sensors (accelerometer, gyroscope) and processing capabilities. By leveraging the smartphone's existing hardware and software, the system achieves accurate braking event detection without adding complex dedicated sensor systems to the helmet, thus resolving the contradiction between measurement precision and device complexity.
3Adaptability or versatility
If helmet-mounted indicator lamp is used, then adaptability to two-wheeled vehicles is improved, but the ease of operation decreases due to integration with personal equipment
Solution Approach 1:
The system automatically detects braking events using the smartphone's sensors and automatically activates the indicator lamp on the helmet without requiring manual intervention from the rider. This self-service operation maintains ease of use while achieving universal adaptability to two-wheeled vehicles, as the system works passively with the rider's existing equipment.
