Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-panel display devices face inefficiencies in the assembly process due to manual connection of display units, leading to potential damage and visible boundaries between units, which degrades image continuity and prolongs installation time.
Innovation Solution
A multi-panel display device design featuring a cabinet system with magnet units, cam lever lockers, and fine adjustment devices, including linear guide grooves and protrusions, allows for precise positioning and secure attachment of display units, preventing collisions and ensuring seamless image continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If display devices are connected by a separate fixing mechanism through manual operation, then the display devices can be assembled into a multi-panel display device, but the process time is lengthened and process efficiency is very low
Solution Approach 1:
The fixing mechanism is segmented into modular components: a fixing protrusion on one display device and a corresponding fixing groove on the adjacent display device. This segmentation allows for quick, tool-free connection by simply engaging the protrusion with the groove, eliminating the need for complex manual assembly procedures and significantly reducing process time.
Solution Approach 2:
The fixing mechanism is designed to be self-aligning and self-locking. The fixing protrusion automatically engages with the fixing groove without requiring external tools or complex manual operations. The cam lever provides a self-service locking function that secures the connection through a simple single-handed operation, greatly improving assembly efficiency.
2Ease of manufacture
If display devices are manually arranged and connected, then the assembly can be completed, but damage due to collision of the display devices can occur
Solution Approach 1:
The fixing mechanism incorporates cushioning elements that are pre-positioned to absorb and distribute impact forces during the assembly process. The cam lever locking mechanism provides gradual engagement rather than sudden impact, preventing collision damage to the display devices while maintaining ease of assembly.
Solution Approach 2:
The fixing protrusion and groove act as intermediary elements between the display devices, providing a controlled interface for connection. This intermediary mechanism guides the devices into proper alignment and secures them without direct collision, protecting the fragile display panels from damage during assembly.
3Ease of operation
If neighboring display devices are not accurately arranged, then the assembly process is simplified, but a boundary region between the neighboring display devices becomes visible degrading image continuity
Solution Approach 1:
The fixing protrusion and groove are designed with asymmetric geometries that provide built-in alignment guidance. The cam lever mechanism incorporates asymmetric engagement surfaces that naturally guide the display devices into the correct relative positions during assembly. This asymmetric design ensures high positioning accuracy while maintaining ease of operation, as the geometry itself provides the alignment function without requiring complex adjustment procedures.
4Reliability
If a separate fixing mechanism is used to connect display devices, then the display devices can be securely attached, but the complexity of the assembly system increases
Solution Approach 1:
The fixing mechanism merges multiple functions into a single integrated system: the fixing protrusion and groove provide both alignment and secure attachment, while the cam lever combines locking and securing functions in one component. This merging of functions reduces the overall number of separate parts and simplifies the assembly system while maintaining high connection reliability through the unified design.
