Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If eye tracking devices are integrated into augmented or virtual reality glasses, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The eye tracking system is divided into separate functional modules: cameras mounted on the glasses frame, optical elements positioned near the lenses, and processing units that can be distributed across the device. This segmentation allows each component to be optimized independently while maintaining overall system precision without requiring complete integration into complex AR/VR headsets.
2Measurement precision
If eye tracking devices are integrated into augmented or virtual reality glasses, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The eye tracking kit is designed with universal mounting capabilities that allow it to be attached to various types of glasses frames (prescription, sunglasses, safety glasses, AR/VR glasses) without requiring custom integration for each device type. The adjustable mounting mechanism and flexible optical path configuration enable the system to adapt to different frame geometries while maintaining tracking precision and user comfort.
3Measurement precision
If eye tracking devices are integrated into augmented or virtual reality glasses, then measurement precision is improved, but adaptability deteriorates
Solution Approach 1:
The mounting mechanism incorporates adjustable and reconfigurable elements that allow the eye tracking kit to adapt dynamically to different glasses frame types. The mounting arms can be positioned at various locations on the frame, and the optical elements can be adjusted to maintain proper alignment with the user's eyes regardless of the specific frame geometry, enabling precise eye tracking across diverse glass types.
4Stability of the object's composition
If eye tracking devices contact the user's nose, then stability is improved, but object-affected harmful factors increase
Solution Approach 1:
The design extracts the mounting function from the nose bridge area and relocates it to the glasses frame structure. The mounting arms attach to the frame temples or front structure, distributing the device weight and securing it without requiring contact with the user's nose. This separation maintains device stability through frame attachment while eliminating all harmful contact with the user's facial features.
5Measurement precision
If eye tracking devices interfere with the user's field of view, then measurement precision is improved, but object-affected harmful factors increase
Solution Approach 1:
The optical elements (lenses, mirrors, beam splitters) are nested within or near the existing glasses lens structure, utilizing the available space between the glasses lenses and the user's eyes. This nested configuration allows the eye tracking optical path to be established without protruding into the user's field of view, maintaining both tracking precision and unobstructed vision through proper spatial arrangement of optical components.
