Solution Overview

Problem

Existing augmented reality glasses require frequent removal and repositioning, causing inconvenience to users as the optical module must be taken off to avoid obstructing the view, leading to a suboptimal user experience.

Innovation Solution

The augmented reality glasses feature rotatable optical modules connected to temple brackets, allowing the optical module to move between a display position and a non-obstructive position, with adjustable mechanisms including grooves, ridges, elastic members, and fasteners to facilitate smooth rotation and secure positioning, enabling seamless transition between usage and non-usage modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the optical module is fixed in front of the lens unit for display, then the display function is improved, but the view obstruction increases

Engineering Contradiction:
Improvedisplay functionVSAvoidview obstruction
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The optical module is made dynamically movable between a first position (in front of the lens unit for display) and a second position (deviating from the front for non-obstruction). The rotatable connection mechanism allows the optical module to transition between these positions, enabling the system to adapt its configuration based on whether display or unobstructed view is the priority.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If the optical module is removed to avoid obstruction, then the view obstruction is reduced, but the user convenience deteriorates

Engineering Contradiction:
Improveview obstructionVSAvoiduser convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Instead of requiring complete removal of the optical module, the invention implements a dynamic rotation mechanism that allows the optical module to be repositioned to a second position where it deviates from the front of the lens unit. This dynamic adjustment eliminates view obstruction while keeping the module attached and easily repositionable when needed.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the optical module is made rotatable for position adjustment, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveposition adjustabilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection between the optical module and the temple bracket is segmented into a rotatable joint, allowing independent movement of the optical module relative to the temple bracket. This segmentation enables position adjustment without requiring complex overall restructuring of the device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rotatable connection mechanism combines the functions of support and position adjustment into a single integrated structure. The temple bracket both supports the optical module and provides the rotation mechanism, merging multiple functions into one component to reduce overall complexity.

Inventive Principle:
Principle #5Merging (Combining)
