Modular Helmet With Detachable Face Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional helmets require separate purchases and storage for different types, such as half face, open face, and full face models, imposing a cost burden and storage challenges on users.
Innovation Solution
A type variable helmet design featuring a half face unit and an under face unit that can be detachably attached, with various coupling modules allowing for conversion between different helmet types, including a mask member and vents for improved functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate helmets are purchased for different types (half face, open face, full face), then each helmet can provide adequate protection for its specific purpose, but the user faces cost burden and storage difficulties
Solution Approach 1:
The helmet is divided into separable modules: a base helmet shell and detachable face cover units. The base shell can be combined with different face cover units (half face cover, open face cover, full face cover) to create different helmet types, allowing one helmet to serve multiple protection functions without requiring separate complete helmets for each type
Solution Approach 2:
The base helmet shell is designed with universal compatibility to work with multiple types of face cover units through standardized coupling modules. This multi-functionality allows a single base shell to provide protection across different scenarios (motorcycle riding, cycling, skiing) by simply changing the face cover unit, eliminating the need to purchase and store multiple separate helmets
2Reliability
If multiple helmet types are purchased for different purposes, then appropriate protection can be provided for each activity, but storage space becomes insufficient
Solution Approach 1:
By segmenting the helmet into a base shell and detachable face cover units, the system reduces storage volume. Instead of storing three complete helmets (half face, open face, full face), the user only needs to store one base shell and three small face cover units, significantly reducing the total storage space required while maintaining all necessary protection types
Solution Approach 2:
The face cover units are designed to be compact and can be stored within or alongside the base helmet shell. The coupling modules allow the face cover units to be attached to or removed from the base shell, enabling easy storage and retrieval without requiring separate storage locations for each helmet type
3Ease of manufacture
If a single helmet is designed with fixed structure, then manufacturing is simple, but adaptability to different purposes is limited
Solution Approach 1:
The helmet is manufactured as separate modular components (base shell and face cover units) that can be independently produced using standard manufacturing processes. This segmentation maintains manufacturing simplicity for each component while enabling versatility through the detachable coupling modules that allow reconfiguration for different purposes
Solution Approach 2:
The base helmet shell is manufactured with universal coupling modules designed to accommodate multiple types of face cover units. This universal design approach maintains relatively simple manufacturing for the base shell while achieving high adaptability, as the same base shell can be paired with different face cover units to serve various protective needs
