Protective Helmet Detachable Battery Socket Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern protective helmets with integrated electric apparatus face challenges in battery replacement due to limited storage capacity and difficulty in accessing batteries while wearing motorcycling gloves, making it laborious and often impossible.
Innovation Solution
The protective helmet features a detachable battery socket and line assembly for easy battery replacement and charging, with a spring device for ejection and a locking assembly for retention, allowing for push-push operation, and a USB charging system for convenient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is firmly integrated into the protective helmet, then the electrical connection is stable and reliable, but the battery replacement becomes laborious and difficult when wearing motorcycling gloves
Solution Approach 1:
The battery system is segmented into a detachable battery unit and a battery socket integrated into the helmet. This allows the battery to be easily removed and replaced by pulling it out from the battery socket opening, while the electrical connection remains stable when inserted. The segmentation resolves the contradiction by enabling both firm connection during use and easy replacement during maintenance.
Solution Approach 2:
The battery connection system transitions from a static firm integration to a dynamic state where the battery can be easily inserted and removed. The battery socket is designed with a spring device that provides automatic engagement when the battery is inserted, ensuring stable electrical connection, while allowing easy extraction by pulling the battery out from the battery frame opening.
2Volume of moving object
If the battery is made small to fit within the helmet, then the helmet volume is reduced, but the battery storage capacity is limited
Solution Approach 1:
The battery is positioned in the lower rear region of the helmet interior, utilizing the vertical and depth dimensions rather than only horizontal space. The battery socket is arranged in the lower region of the helmet, allowing the battery to be inserted in a vertically upward direction, effectively using the helmet's three-dimensional interior space to accommodate the battery while maintaining compact overall dimensions.
3Ease of operation
If the battery is accessible for replacement, then easy battery replacement is achieved, but the battery may become loose or improperly positioned
Solution Approach 1:
The battery socket incorporates a spring device that automatically engages with the battery when inserted, providing self-positioning and secure retention without requiring manual adjustment. The spring mechanism ensures the battery is firmly held in place during use, while still allowing easy removal by pulling the battery out from the battery frame opening. This self-service mechanism resolves the contradiction between accessibility and stability.
