Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In portable electronic devices, the integration of electro-optical devices and sound-production bodies often leads to increased thickness or size due to separate mounting and acoustic design requirements, limiting the reduction in size and thickness of the device.
Innovation Solution
An electro-optical device design where the sound-production vibrating body is directly fixed to a sound-production frame on the rear surface of the electro-optical panel, creating a sound-production air space and allowing for compact mounting and reduced acoustic interference, enabling a more compact and flexible device design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electro-optical device and sound-production body are separately mounted in the case, then the acoustic design can be performed, but the size and thickness of the apparatus are increased
Solution Approach 1:
The patent merges the electro-optical device and sound-production body into a single integrated unit. The sound-production frame is disposed on the rear surface of the electro-optical panel, and the sound-production vibrating body is fixed directly to the sound-production frame, combining both functions in one compact structure without requiring separate mounting in the case.
Solution Approach 2:
The electro-optical device is designed to serve multiple functions: it acts as both a display device and a sound-production device. The integrated structure allows the electro-optical panel and sound-production body to coexist in a single unit, enabling the apparatus to perform both visual and audio functions simultaneously without increasing overall size.
2Length of stationary object
If the display section and sound section are disposed to overlap each other, then the thickness of the case can be reduced, but the acoustic design is restricted
Solution Approach 1:
The display section and sound section are merged into a single integrated electro-optical device where the sound-production frame is disposed on the rear surface of the electro-optical panel. This overlapping arrangement reduces case thickness while maintaining acoustic design flexibility through the integrated structure.
Solution Approach 2:
The sound-production frame creates a dedicated sound-production air space with specific acoustic properties on the rear surface of the electro-optical panel. This localized acoustic design allows for optimized sound production while maintaining the overall compact thickness of the device.
3Reliability
If the sound-production body is housed in the case, then the acoustic design can be performed, but the size reduction is obstructed
Solution Approach 1:
The sound-production body is extracted from the traditional case housing and integrated directly onto the electro-optical panel. The sound-production frame is disposed on the rear surface of the electro-optical panel, eliminating the need for separate case accommodation and reducing overall device volume.
Solution Approach 2:
The sound-production body is nested within the structure of the electro-optical device itself. The sound-production frame and vibrating body are incorporated into the rear surface structure of the electro-optical panel, creating a compact nested arrangement that reduces overall volume while maintaining acoustic functionality.
4Reliability
If the electro-optical device and sound-production body are separately mounted on a substrate, then the acoustic design can be performed, but the number of parts and manufacturing cost increase
Solution Approach 1:
The electro-optical device and sound-production body are merged into a single integrated unit with shared structural components. The sound-production frame is disposed on the rear surface of the electro-optical panel, eliminating the need for separate substrates and mounting structures, thereby reducing the number of parts and manufacturing complexity.
