Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If head-mounted display devices are used for virtual reality, then virtual reality display function is achieved, but weight increases and wearing convenience deteriorates
Solution Approach 1:
The display device is segmented into a front end assembly containing the display components and separate legs for wearing, allowing the heavy display portion to be minimized while maintaining functionality. The legs are further segmented into front and rear segments that can rotate independently.
Solution Approach 2:
The legs utilize flexible hinges (torsion mechanism and rotation mechanism) that allow the structure to adapt to different head sizes and shapes while maintaining a lightweight construction. The flexible joints enable the legs to conform to the user's head without adding significant weight.
2Stability of the object's composition
If legs are made rigid for stable wearing, then wearing stability improves, but storage space increases
Solution Approach 1:
The legs transition from a static rigid structure to a dynamic structure with two degrees of freedom (torsion and rotation). The torsion mechanism allows the front segment to rotate relative to the front end assembly, while the rotation mechanism allows the rear segment to rotate relative to the front segment, enabling compact folding for storage while maintaining stability during use.
Solution Approach 2:
The foldable leg structure allows the rear segment to be positioned behind the front end assembly when folded, creating a nested configuration that minimizes storage volume while maintaining the necessary length and stability when worn.
3Stability of the object's composition
If torsion mechanism is added for head gripping, then wearing stability improves, but device complexity increases
Solution Approach 1:
The torsion mechanism acts as an intermediary between the front end assembly and the wearable legs, providing the necessary gripping force and stability while isolating the complexity of the adjustment mechanism from both the display components and the leg structure.
Solution Approach 2:
The torsion mechanism automatically adjusts to different head sizes and shapes through elastic deformation, providing stable gripping without requiring manual adjustment or complex control systems. The mechanism self-regulates the gripping force based on the encountered resistance.
4Volume of moving object
If foldable legs with rotation mechanism are implemented, then storage compactness improves, but manufacturing complexity increases
Solution Approach 1:
The leg structure is divided into multiple segments (front segment, rear segment) connected by rotation mechanisms, allowing each segment to be manufactured separately and assembled, which simplifies the manufacturing process compared to creating a single complex foldable component.
Solution Approach 2:
The rotation mechanisms use standard hinge designs with defined rotation angles, transforming the complex foldable structure into a series of simple rotational joints with standardized parameters, making manufacturing and assembly more straightforward.
