Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hard outer shell and impact absorbing inner shell are used, then impact absorption is improved, but device complexity increases
Solution Approach 1:
The impact absorbing layer is segmented into multiple independent impact absorbing structures (first, second, third structures) that can be laterally compressed and positioned independently within the helmet body. Each structure has engagement portions that interface with the outer shell separately, allowing modular assembly and independent optimization of each segment's impact absorption characteristics.
2Ease of operation
If adjustable fit systems are added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The fit system includes an adjustable assembly with a dial mechanism that enables dynamic adjustment of the helmet's internal volume and strap tension. The dial can be rotated to tighten or loosen the fit, and the system includes movable components that allow the helmet to adapt to different head sizes and shapes while maintaining a secure fit.
3Adaptability or versatility
If accessory mounting mechanisms are added, then adaptability is improved, but device complexity increases
Solution Approach 1:
The outer shell incorporates universal mounting structures with engagement portions that can accommodate multiple types of accessories (lights, cameras, sensors). These mounting structures are integrated into the helmet's existing impact absorbing framework, allowing a single system to serve both protective and accessory mounting functions without requiring separate dedicated mounting mechanisms.
4Ease of manufacture
If modular impact absorbing structures are used, then ease of manufacture is improved, but manufacturing precision requirements increase
Solution Approach 1:
The impact absorbing layer is divided into discrete modular structures that can be manufactured separately and then assembled into the helmet body. Each structure includes engagement portions with interfaces designed to mate with corresponding features in the outer shell, enabling independent manufacturing of components followed by precise assembly through lateral compression and engagement.
Solution Approach 2:
The engagement portions serve as intermediary elements between the impact absorbing structures and the outer shell. These engagement portions include interfaces that mediate the connection, allowing for precise positioning and secure attachment while accommodating minor variations in manufacturing tolerances through the lateral compression mechanism.
