Foldable Handheld Device Stereoscopic Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held electronic devices with stereoscopic display sections have poor viewability when used with naked eyes due to a single housing design, which limits the suitable viewing angle and makes the screen prone to contamination.
Innovation Solution
A hand-held electronic device with a foldable design featuring a first housing for stereoscopic display and a second housing for operation, where the first housing includes a stereoscopic display section and parallax adjusting operation, and the second housing has a shutter button and touch panel, reducing the likelihood of contamination and improving viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single housing design is used for hand-held electronic devices with stereoscopic display, then the device structure is simple, but the viewability in stereoscopic viewing with naked eyes deteriorates
Solution Approach 1:
The device is divided into two separate housings: a first housing containing the stereoscopic display section and a second housing containing operation sections. This segmentation allows the display housing to be optimized for viewing angles and the operation housing to provide ergonomic controls, resolving the contradiction between structural simplicity and viewing quality.
2Adaptability or versatility
If the stereoscopic display section is provided with operation sections, then the operation functionality is integrated, but the screen is prone to contamination from user touching
Solution Approach 1:
Operation sections are relocated to the second housing, physically separating the display area from the control area. This prevents users' fingers from directly touching the stereoscopic display screen during operation, eliminating fingerprint contamination while maintaining full operational functionality through the second housing's controls.
3Volume of moving object
If the viewing angle of stereoscopic display is limited, then the display structure is compact, but the viewability deteriorates
Solution Approach 1:
The solution moves the operation sections to a different spatial dimension by placing them in a separate second housing rather than on the display housing. This allows the first housing to maintain a compact form factor optimized for stereoscopic viewing while the second housing provides accessible controls, effectively adding a dimensional separation between display and operation functions.
