Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays are inconvenient for use in bright environments and lack portability, as they are designed for closed areas and not suitable for mobile use due to structural limitations and lack of transparency.
Innovation Solution
A head-mounted display with a pair of headphones and rotatable arms, one made of transparent flexible display and the other of opaque material, allowing for various positions and integration of sensors, cameras, microphones, and communication modules to enhance usability and safety, with a control unit managing image and sound output based on arm positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a head-mounted display uses a traditional closed-area design with opaque display surfaces, then it provides excellent image quality and stability, but it lacks transparency and is not suitable for mobile use in bright environments
Solution Approach 1:
The patent applies the dynamics principle by making the display surface transparent and flexible, allowing it to be rotated and repositioned dynamically. The display can switch between facing forward, facing backward, or being stored on the back of the head, enabling the system to adapt to different usage scenarios including mobile use in bright environments while maintaining image quality
2Stability of the object's composition
If a head-mounted display is designed for closed areas with fixed functions, then it provides stable performance, but it lacks portability and cannot be safely used in motion
Solution Approach 1:
The patent implements dynamics by enabling the display to rotate and reposition dynamically. The display can be rotated to face the user during stationary use for stable performance, and can be repositioned to the back of the head or rotated away during mobile use to ensure safety and portability
Solution Approach 2:
The patent applies universality by integrating multiple functions into the head-mounted display system, including transparent display, rotation mechanism, position detection sensors, cameras, microphones, and communication modules. This multi-functional design enables the device to operate stably in closed areas while also being adaptable for mobile use in various environments
3Device complexity
If a head-mounted display provides fixed functions recognizing only the front view, then it simplifies the control system, but it reduces usability in various directions and environments
Solution Approach 1:
The patent applies dynamics by implementing a rotation mechanism that allows the display to dynamically change its facing direction. Position detecting sensors automatically detect the display's orientation and control the system to recognize and capture images from different directions (front, back, left, right), providing multi-directional usability without significantly increasing control complexity
Solution Approach 2:
The patent implements self-service through position detecting sensors that automatically detect the display's orientation and trigger appropriate capture functions. The system autonomously determines which direction to capture images based on the display's position, eliminating the need for manual direction selection and reducing control complexity while enhancing versatility
