Bicycle Helmet Rear Camera and Display Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclists face challenges while cycling due to the weight and inconvenience of carrying recording devices, limited communication, lack of rear view functionality in helmets, and complex replacement of additional devices, which increases risk and delays.
Innovation Solution
A protective helmet with a rear-facing camera integrated with intelligent hardware, including a GPS module, sensors, and a display unit, allowing for rear view monitoring, wireless communication, and easy assembly/disassembly, which also provides GPS navigation and entertainment features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rear camera and intelligent hardware are integrated into the helmet, then rear view monitoring and communication capabilities are improved, but device complexity increases
Solution Approach 1:
The patent combines the rear camera, display unit, GPS module, sensors, and communication hardware into an integrated helmet system. The rear camera (7) is mounted on the helmet body (1) and electrically connected to intelligent hardware, while the display unit (4) is positioned to be visible to the rider. This merging of multiple functions into a single wearable device provides comprehensive safety and communication capabilities without requiring separate carrying devices.
Solution Approach 2:
The helmet is designed as a multi-functional device that simultaneously provides rear view monitoring through the rear camera and display unit, navigation through GPS tracking, collision detection through sensors (gyroscope, accelerometer, gravity sensor), and wireless communication through Bluetooth module. This universal design allows the helmet to perform multiple safety and communication functions, replacing the need for separate recording devices, communication devices, and navigation devices.
2Ease of repair
If a main support with rocker arm module is detachably attached to the helmet body, then ease of maintenance and replacement is improved, but device complexity increases
Solution Approach 1:
The helmet system is divided into separate modular components: the helmet body (1) with integrated rear camera, the detachable main support (3), and the rocker arm module (31) with display unit (4) and front camera (5). The main support can be detached from the helmet body, and the rocker arm module can be replaced independently. This segmentation allows for easy maintenance and replacement of specific modules without affecting the entire helmet system.
Solution Approach 2:
The connection between the main support and helmet body is designed to be detachable rather than permanent. The main support (3) can be attached or detached from the helmet body (1) as needed, providing dynamic reconfigurability. This allows users to remove the main support for charging, maintenance, or replacement without permanently altering the helmet structure.
3Reliability
If multiple sensors and intelligent hardware are integrated into the helmet, then safety monitoring and communication capabilities are improved, but weight increases
Solution Approach 1:
Multiple safety and communication components including GPS tracking module, gyroscope, gravity sensor, accelerometer, Bluetooth module, microphone module, and headphone module are integrated into the helmet's main support and rocker arm module. By combining these functions into a single wearable unit rather than requiring separate devices, the total system weight is reduced while maintaining comprehensive safety monitoring and communication capabilities.

AI summary
A rear-view front-play smart safety helmet, comprising a helmet body (1) and several ventilation holes (2) arranged thereon, the rear of the helmet body (1) being provided with a rear camera (7) which is electrically connected to smart hardware arranged in front of said camera, the smart hardware comprising a main support (3) detachably mounted on a side of the helmet body (1), a display unit (4) and a front camera (5) being mounted on the front of the main support (3) via a rocker arm module (31). A user may store pictures captured by the front camera (5) in a memory and, after turning on the rear camera, may also project images onto the display unit (4) in order to see what is happening to the rear. Via the rear camera arranged at the rear of the helmet, the user may play captured images via the transmissive optical module in front of one eye, allowing the rider to know what is happening on the road behind him, thereby ensuring the safety of the rider.
