Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety helmets lack the operational reliability to securely attach and maintain modules, such as communication units, which can interfere with their functionality or get damaged due to improper attachment.
Innovation Solution
A safety helmet design featuring an arched helmet shell, a bearing support structure, and a module adapter system that allows for detachable and secure attachment of modules to the helmet shell or the bearing support structure, ensuring reliable operation and easy replacement or upgrading of modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If modules are attached to safety helmets using conventional methods, then the helmet can carry additional functional units, but the attachment reliability is insufficient and modules may interfere with helmet functionality or get damaged
Solution Approach 1:
The attachment system is divided into separate components: a coupling element integrated into the helmet shell, a module adapter with corresponding coupling features, and the module itself. This segmentation allows each component to be optimized independently while ensuring reliable connection through standardized interfaces.
Solution Approach 2:
The coupling element and module adapter are designed with universal interfaces that can accommodate different module types while maintaining consistent attachment reliability. The standardized coupling mechanism enables various functional modules to be attached to the same helmet using the same attachment system.
2Reliability
If modules are securely attached to safety helmets, then operational reliability improves, but the ability to easily replace or upgrade modules decreases
Solution Approach 1:
The attachment system transitions from a fixed, permanent connection to a dynamic, reversible connection. The module adapter enables modules to be easily attached and detached while maintaining secure attachment during use, allowing for flexible replacement and upgrading without compromising attachment reliability.
Solution Approach 2:
The module adapter serves as an intermediary component between the helmet's coupling element and the module. This intermediate element facilitates easy module replacement while ensuring reliable attachment, as the adapter remains permanently attached to the helmet while modules can be quickly exchanged.
3Stability of the object's composition
If a fixed attachment system is used for modules on safety helmets, then attachment stability is improved, but adaptability to different module types decreases
Solution Approach 1:
The coupling element and module adapter are designed with universal interfaces that maintain stable attachment while accommodating different module types. The standardized coupling mechanism ensures attachment stability through consistent mechanical engagement, while the universal design enables compatibility with various module configurations.
Solution Approach 2:
The attachment system provides dynamic adaptability by allowing the same stable coupling mechanism to work with different module types. The module adapter remains permanently attached to provide stable mounting, while the detachable module interface enables adaptation to different functional requirements.
4Device complexity
If modules are attached directly to the helmet shell, then the attachment system is simplified, but the risk of interference with helmet functionality and damage increases
Solution Approach 1:
The module adapter serves as a protective intermediary between the helmet shell and the module. It is permanently attached to the helmet's coupling element, providing a stable mounting point that isolates the module from direct contact with the helmet shell, thereby reducing the risk of interference with helmet functionality and minimizing damage risk.
Solution Approach 2:
The attachment system is segmented into the helmet shell, coupling element, module adapter, and module. This segmentation creates buffer zones and independent components that reduce the transmission of harmful forces and interference between the module and helmet shell, while maintaining overall system simplicity.
