Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional strap system is used for mounting head-mounted display, then the structure is simple, but the user cannot properly adjust and wear the head-mounted display comfortably
Solution Approach 1:
The strap system is divided into multiple functional segments: rigid guide segments for structural support and positioning, flexible segments for adaptability to head contours, and semi-rigid segments for conforming to head shapes. This segmentation allows each part to perform its specific function optimally while collectively providing adjustable and comfortable wear.
Solution Approach 2:
The strap system combines different material properties by integrating rigid, flexible, and semi-rigid segments. The rigid guide segments provide structural stability, the flexible segments offer elasticity and comfort, and the semi-rigid segments balance both properties. This composite structure resolves the contradiction between simplicity and adjustability.
2Adaptability or versatility
If existing strap systems are used, then the manufacturing is simple, but the user experience is negatively affected due to difficulty in proper adjustment and comfortable wear
Solution Approach 1:
Dividing the strap into modular segments with different rigidity levels enables mass production of standardized components that can be assembled to fit various head sizes and shapes. Each segment can be manufactured independently using optimized processes for its specific material properties.
Solution Approach 2:
The strap system utilizes segments with varying rigidity parameters (rigid, semi-rigid, flexible) to achieve adaptability across different user head geometries. By controlling the rigidity parameter of each segment, the system can accommodate a wide range of head sizes and shapes while maintaining manufacturability through standardized production of each segment type.
3Stability of the object's composition
If a rigid strap system is used, then the structural stability is high, but the comfort and adaptability to different head shapes is reduced
Solution Approach 1:
The strap system employs a composite structure combining rigid guide segments for stability with flexible and semi-rigid segments for conformity. The rigid segments maintain structural integrity and positioning accuracy, while the other segments adapt to the user's head shape, resolving the contradiction between stability and adaptability.
Solution Approach 2:
Different segments of the strap system have different rigidity qualities tailored to their specific functions. The rigid guide segments provide localized structural stability where needed, while flexible and semi-rigid segments provide localized adaptability to head contours. This local differentiation of material properties resolves the contradiction between overall structural stability and global adaptability.

AI summary
A strap system and a method for wearing the strap system are disclosed. The strap system includes a first flexible segment comprising a first stretchable band; a first semi-rigid segment to conform to a portion of the user's head and comprising a first arc portion to extend from above a user's first ear to below the user's occipital lobe; and a first rigid guide segment connected to the first flexible segment and the first semi-rigid segment. The first flexible segment extends beyond a first end of the first rigid guide segment and the first semi-rigid segment extends from a second end of the first rigid guide segment, the first and second ends of the first rigid guide segment being opposite to each other in a lateral dimension. The first flexible segment is stretchable within the first rigid guide segment along the lateral dimension.
