Display Device Frame Connection Mechanism for Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in securely connecting multiple components, such as frames and back covers, which affects their structural integrity and ease of assembly/disassembly, particularly under various mechanical stresses and for functional enhancements like repairability.
Innovation Solution
The display device employs a unique connection mechanism between the first and second frames using a connecting surface and locking rib/ groove system, along with holders for the back cover, allowing secure surface contact and easy reconnection, utilizing Al-containing materials for the frame and injection molding for holders, enabling secure fastening with minimal screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components (frames and back covers) are connected using traditional fastening methods, then structural integrity can be maintained, but assembly and disassembly become complex and time-consuming
Solution Approach 1:
The connection structure is divided into distinct segments: a connecting protrusion on one component and a corresponding connecting groove on another component. This segmentation allows for modular assembly where parts can be easily connected and disconnected while maintaining structural integrity through the interlocking geometry of the segmented components.
Solution Approach 2:
The connecting groove is designed to receive and nest the connecting protrusion, creating a nested configuration where one component fits into another. This nesting mechanism provides secure connection through surface contact while enabling simple assembly by sliding components together and easy disassembly by reversing the sliding motion.
2Strength
If multiple screws are used to fasten components, then connection strength is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention extracts the fastening function from traditional screw-based systems and integrates it directly into the structural components themselves. The connecting protrusion and groove are formed as integral parts of the frames and back covers through injection molding, eliminating the need for separate screws and fasteners while maintaining connection strength through optimized surface contact geometry.
Solution Approach 2:
The connection structure is designed to be self-fastening through the interlocking geometry of the protrusion and groove. When components are assembled, the protrusion automatically engages with the groove and locks into place through surface contact, providing self-service fastening without requiring additional fastening operations or complex assembly procedures.
3Stability of the object's composition
If traditional connection methods are used, then structural stability is maintained, but repairability and functional enhancement become difficult
Solution Approach 1:
The connection structure enables dynamic reconfigurability, allowing components to be easily assembled and disassembled multiple times. This dynamic capability facilitates repair operations and functional enhancements by permitting access to internal components while maintaining structural stability through the reliable interlocking mechanism of the protrusion and groove design.
