Spherical Hinge for Electronic Eyewear Display Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic eyewear viewing devices face limitations in adjusting the display module's position due to the need for separate mechanical hinges for each axis of movement, which restricts angle directions and size changes, and designs with too much freedom can be counter-effective.
Innovation Solution
An electronic eyewear viewing device featuring a primary and secondary pivoting hinge system with at least partially spherical joints, allowing rotation around multiple axes without separate mechanical hinges for each axis, enabling optimal positioning and rotation of the display module within a compact area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate mechanical hinges are used for each axis of movement, then the display module can be positioned accurately, but the device complexity increases and the available space is limited
Solution Approach 1:
The patent combines multiple hinge functions into a single integrated spherical joint mechanism. The spherical joint allows rotation around multiple axes (pitch and yaw) simultaneously, eliminating the need for separate mechanical hinges for each axis. This merging reduces device complexity while maintaining positioning accuracy through the inherent multi-axis capability of the spherical geometry.
Solution Approach 2:
The spherical joint serves multiple functions: it provides rotation around the first axis, rotation around the second axis, and accommodates the passage of the second axis through the first axis via a hole. This universal joint design enables a single component to perform what previously required multiple specialized hinges, reducing overall device complexity while preserving full positioning capability.
2Ease of operation
If more axes of movement are provided, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The spherical joint merges multiple rotation axes into a single integrated structure. The first spherical joint allows rotation around the first axis, while the second spherical joint allows rotation around the second axis. This merging approach provides multi-axis adjustment flexibility without requiring separate complex hinge mechanisms for each axis, thus improving ease of operation without proportionally increasing device complexity.
Solution Approach 2:
The use of spherical joints leverages the geometric properties of spheres to enable rotation around multiple axes. The spherical shape inherently provides freedom of movement in multiple directions, allowing the display module to be adjusted along the first axis and second axis without requiring separate mechanical hinges for each degree of freedom.
3Adaptability or versatility
If the display module is made adjustable in multiple axes, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent merges multiple adjustment functions into an integrated hinge system where the first spherical joint and second spherical joint work together. The first spherical joint provides rotation around the first axis, and the second spherical joint provides rotation around the second axis, with the second axis passing through the first axis via a hole. This merging provides adaptability for different user needs while avoiding the complexity of separate adjustment mechanisms.
Solution Approach 2:
The hinge system is segmented into distinct spherical joint components, each responsible for specific rotational freedom. The first spherical joint handles rotation around the first axis, while the second spherical joint handles rotation around the second axis. This segmentation allows each component to be optimized for its specific function while working together to provide overall adaptability, reducing the complexity that would arise from a monolithic multi-axis mechanism.
