Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a movement device with fixed interaction elements is used, then the device structure is simple, but the versatility and customization options for controlling visor movement are limited
Solution Approach 1:
The interaction element is divided into multiple interchangeable components (first interaction element and second interaction element) that can be separately selected and combined. This segmentation allows different movement characteristics to be achieved by changing components without redesigning the entire device, thus improving versatility while maintaining structural simplicity.
Solution Approach 2:
The movement device is designed to accommodate multiple types of interaction elements that can be interchangeably mounted on the same base structure. This universal design allows a single device platform to provide multiple visor movement characteristics (different speeds, forces, and sensations) by simply changing the interaction element, thereby achieving versatility without increasing overall device complexity.
2Strength
If the interaction element is made of hard material, then the durability is improved, but the comfort and smoothness of visor movement deteriorates
Solution Approach 1:
The interaction element is constructed using composite materials that combine hard outer layers for durability with softer inner layers or surface treatments that provide smooth movement. This composite structure allows the element to withstand repeated use while maintaining comfortable interaction with the visor, resolving the contradiction between durability and smoothness.
3Adaptability or versatility
If the interaction element has fixed geometry, then the manufacturing is simple, but the ability to provide different movement sensations and speeds is limited
Solution Approach 1:
The interaction element geometry is segmented into standardized base shapes with variable surface features. This allows manufacturing of common base geometries in high volumes, while customization is achieved through adding or modifying surface elements (ridges, grooves, textures) that can be produced using cost-effective processes like injection molding variations or post-manufacturing treatments.
4Measurement precision
If the interaction element provides strong friction for precise positioning, then the position control is improved, but the energy required to move the visor increases
Solution Approach 1:
The interaction element surface is designed with periodic features (ridges, grooves, or teeth) that engage with corresponding features on the visor. These periodic structures provide discrete positioning points with high friction for precise control, while allowing the visor to move smoothly between points with lower energy requirements. The periodic engagement pattern enables precise positioning without requiring continuously high friction.

AI summary
The present disclosure relates to a movement device (10) for a helmet (12) for moving a first element (16) of the helmet (12) in relation to a second element (14) of the helmet (12). The movement device (10) includes a movable body (24) fixedly associated with the first element (16), a base body (20) fixedly associated with the second element (14), an interaction element (35) associated with the movable body (24) and an interaction counter-element (36, 136, 236) associated with the base body (20). The interaction element (35) and the interaction counter-element (36, 136, 236) are able to interact mutually for holding, in at least one given position, the movable body (24) in relation to the base body (20). At least one of said interaction element (35) and said interaction counter-element (36, 136, 236) is structurally independent from the movable body (24) or the base body (20) with which it is associated.
