Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel mounting systems face challenges in achieving a uniform and accurate continuous display surface due to tolerance stack-up from multiple connecting surfaces, making it difficult to achieve high resolution displays.
Innovation Solution
A video display wall system with alignment mounts that have fixed depth dimensions between display panels and a support structure, allowing for precise alignment and reduced tolerance stack-up, using connectors like magnets and threaded connectors to secure panels in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple connecting surfaces and components are used to mount display panels, then the display panels can be securely mounted, but tolerance stack-up occurs leading to difficulty in achieving a uniform display surface
Solution Approach 1:
The patent combines multiple functions (mounting, alignment, and electrical connection) into a single integrated connector assembly. This eliminates multiple separate connecting surfaces and reduces tolerance stack-up by consolidating what was previously three separate interfaces into one unified interface between the display panel and support structure.
Solution Approach 2:
The connector assembly serves multiple functions simultaneously: it provides mechanical mounting support, ensures precise alignment of display panels, and establishes electrical connections. This multi-functionality reduces the number of separate components needed and minimizes cumulative tolerances across multiple interfaces.
2Reliability
If separate wiring harnesses and electrical connectors are used, then electrical connections can be established, but the panels must be in a specific rotational orientation increasing assembly complexity
Solution Approach 1:
The patent integrates electrical connectors directly into the mounting connector assembly, eliminating separate wiring harnesses and standalone electrical connectors. This integration removes the requirement for specific rotational orientations during assembly and reduces the overall number of components that must be installed.
Solution Approach 2:
The unified connector assembly performs both mechanical mounting and electrical connection functions in a single component, eliminating the need for separate electrical connection steps and reducing assembly complexity while maintaining reliable electrical connections.
3Manufacturing precision
If tightly controlled tolerances are used in conventional systems, then some uniformity can be achieved, but the system complexity and cost increase
Solution Approach 1:
By integrating multiple functions into a single connector assembly, the patent reduces the number of interfaces where tolerances must be controlled. This approach achieves display surface uniformity through fewer, more manageable tolerance requirements rather than tightly controlling multiple separate interfaces.
Solution Approach 2:
The alignment features within the connector assembly act as intermediaries that accommodate and compensate for tolerances in the display panels and support structure. These alignment features provide a buffering mechanism that reduces the impact of manufacturing variations without requiring extremely tight tolerances across all components.
