Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device assemblies face challenges in maximizing the operable display area while minimizing lateral dimensions and overall thickness, while ensuring the display's rigidity and secure placement within the device, and facilitating easy separation and replacement of the display module.
Innovation Solution
A mobile device assembly design featuring a chassis and circumferential frame that compressively secure a display module between them using adhesive attachment, allowing for secure display placement without additional mounting means, enabling easy separation and replacement, and minimizing the need for mechanical fasteners, thus allowing a larger operable area coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the mechanical structure is minimized to maximize operable display area, then the display area coverage is improved, but the structural support and rigidity deteriorate
Solution Approach 1:
The mechanical structure is segmented into a circumferential frame and a separate chassis, where the frame provides peripheral support and the chassis provides rear support. This segmentation allows the display to be secured at critical points without requiring a full mechanical structure, thus maximizing display area while maintaining necessary support.
Solution Approach 2:
Traditional mounting structures are extracted and replaced with adhesive attachment. The display module is removed from mechanical fastening systems and secured solely through adhesive bonds between the chassis, frame, and display, eliminating the need for complex mechanical mounting components.
2Ease of operation
If adhesive attachment is used to secure the display, then the ease of separation is improved, but the reliability of secure placement deteriorates
Solution Approach 1:
Adhesive attachment is applied locally at critical interfaces: between the chassis and display module, between the frame and display module, and between the frame and chassis. This localized adhesive application provides sufficient secure placement while maintaining ease of separation when needed, avoiding the need for permanent mechanical fastening.
3Length of stationary object
If the device thickness is minimized, then the overall compactness is improved, but the structural integrity deteriorates
Solution Approach 1:
The support structure is designed asymmetrically with the circumferential frame positioned at the periphery and the chassis at the rear, creating a distributed support system that provides maximum structural integrity with minimal thickness. The frame and chassis work together in an asymmetric arrangement to prevent display movement without requiring uniform thickness throughout.

AI summary
A mobile device assembly comprises a display module having a display assembly, the display assembly having a front surface, a back surface, and a peripheral edge surface; a chassis supporting the display module from the back surface of the display assembly; and a circumferential frame having a front frame portion defining a front opening smaller than a display module width. The display module is pressed between the front frame portion and the chassis. The chassis is attached, by means of an adhesive, to the circumferential frame.
