Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hard outer shell and impact absorbing inner shell are used, then safety and impact protection are improved, but device complexity increases
Solution Approach 1:
The impact absorbing layer is segmented into multiple independent impact absorbing structures (first, second, third structures) with different geometries positioned at different locations within the helmet shell. Each structure independently absorbs impact energy from different directions, providing comprehensive protection while maintaining a relatively simple overall structure.
Solution Approach 2:
Different impact absorbing structures are strategically positioned at specific locations within the helmet shell to address local impact risks. The first structure is positioned to absorb impacts from a first direction, the second from a second direction, and the third from a third direction, creating localized protection zones throughout the helmet.
2Reliability
If modular impact absorbing structures are implemented, then safety and impact absorption are improved, but manufacturing complexity increases
Solution Approach 1:
The impact absorbing layer is divided into multiple separate modular structures that can be independently manufactured and then assembled into the helmet shell. This segmentation allows each structure to be produced using standard manufacturing processes, simplifying production while enabling complex overall geometry.
Solution Approach 2:
The modular impact absorbing structures serve multiple functions: they absorb impact energy from specific directions, provide structural support at critical locations, and can be easily replaced or adjusted. This multi-functionality reduces the need for additional separate components.
3Adaptability or versatility
If adjustable fit systems are added, then fit customization and comfort are improved, but device complexity increases
Solution Approach 1:
The fit system incorporates adjustable elements that allow dynamic modification of the helmet's fit to the rider's head. The adjustable elements enable the helmet to adapt to different head sizes and shapes, providing a customized fit while maintaining a relatively simple overall system design.
4Adaptability or versatility
If accessory mounting mechanisms are integrated, then versatility and functionality are improved, but device complexity increases
Solution Approach 1:
The helmet shell is designed with integrated accessory mounting mechanisms that allow various accessories to be attached to different locations on the helmet. These mounting points are incorporated into the existing shell structure, enabling multi-functionality without requiring separate attachment systems.
