Helmet Suspension Link Element Tool-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective helmets with suspension systems require multiple parts and tools for assembly and disassembly, which complicates the process and contradicts the need for rapid assembly in hazardous situations.
Innovation Solution
A protective helmet assembly with a reduced number of parts, featuring a link element that connects the helmet suspension to the outer shell without the need for tools, and a releasable fastening mechanism for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional protective helmets with suspension systems are assembled using multiple parts and tools, then the structural integrity and reliability are improved, but the assembly time and operational complexity increase
Solution Approach 1:
The patent merges the suspension system with the outer shell by integrating attachment mechanisms directly into the shell structure. The suspension system is pre-attached to the outer shell as a unified assembly, eliminating the need for separate tool-based fastening operations and reducing assembly time while maintaining structural integrity through the integrated design.
Solution Approach 2:
The suspension system is pre-assembled and pre-attached to the outer shell during manufacturing. The attachment mechanisms are pre-positioned and configured before field assembly, so that during emergency or hazardous situations, the helmet can be quickly donned without requiring tool-based assembly operations.
2Adaptability or versatility
If traditional protective helmets use multiple parts for suspension system, then the adaptability and adjustment options are improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The integrated attachment mechanisms serve multiple functions: they provide structural attachment, allow for suspension adjustment, and enable quick release capabilities. This multi-functionality reduces the number of separate parts needed while maintaining adaptability and adjustment options for different head sizes and preferences.
3Manufacturing precision
If traditional protective helmets require tools for assembly, then the manufacturing precision and connection reliability are improved, but the ease of manufacture and operational simplicity worsen
Solution Approach 1:
The attachment mechanisms are designed to be self-attaching and self-adjusting without requiring external tools. The suspension system automatically secures to the outer shell through integrated clips, snaps, or friction-fit interfaces that maintain reliable connections while eliminating the need for tool-based assembly operations.
