Wearable Image Display Positioning With Discrete Angular Locking

The patent implements a dynamic positioning system where the movable unit can be adjusted to multiple discrete angular positions (including upper, intermediate, and lower positions) relative to the base unit. This allows the system to transition from a static stable position to multiple dynamically adjustable positions, each capable of being locked stably through the positioning mechanism.

The patent introduces a positioning mechanism comprising positioning portions (such as positioning protrusions and positioning recesses) that act as intermediaries between the movable unit and base unit. These positioning elements engage at specific locations to provide stable locking at multiple positions, preventing the instability that would otherwise occur at upper positions.

The patent divides the adjustment system into discrete, modular components including multiple positioning portions located at different angular positions, a rotation mechanism with fitting mechanisms, and detachable connection structures. This segmentation allows each component to perform a specific function while maintaining overall system adaptability without excessive complexity.

The patent implements local quality by providing positioning portions at specific discrete locations rather than continuous adjustment. The positioning portions are strategically placed at upper, intermediate, and lower positions to provide stable locking at these key locations, while the overall structure remains relatively simple through the use of standard mechanical connection elements.
