PCB Sliding Mounting Structure for Screwless Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mounting Printed Circuit Boards (PCBs) in display apparatuses require screws, increasing manufacturing costs and time, and often necessitate additional tools for assembly and maintenance.
Innovation Solution
A PCB mounting structure that uses a sliding mechanism with a mounting member and a mounting portion on the chassis, eliminating the need for screws and tools, allowing for easy assembly and disassembly by sliding the PCB onto board resting portions with integrated guide and stopper mechanisms for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to couple components, then the connection strength is improved, but the manufacturing time and cost increase due to additional fastening tools and procedures
Solution Approach 1:
The patent extracts and eliminates the screw fastening mechanism from the assembly process. Instead of using screws to couple the PCB to the chassis, the design directly integrates the PCB mounting structure into the chassis body, removing the need for separate fastening operations and tools while maintaining connection strength through the integrated structural design.
Solution Approach 2:
The patent merges the PCB mounting function with the chassis structure by integrating board resting portions directly into the chassis body. This combination eliminates the need for separate mounting brackets or fastening mechanisms, allowing the PCB to be secured through the integrated chassis design itself, thereby reducing manufacturing steps and time.
2Reliability
If screws are used to couple components, then the connection reliability is improved, but the device complexity increases due to additional fastening tools and assembly steps
Solution Approach 1:
The patent removes the screw fastening system and associated tools from the device complexity. By integrating the mounting function directly into the chassis structure, the design eliminates the need for separate fastening operations, reducing both the number of components and the complexity of assembly procedures while maintaining reliable connections.
Solution Approach 2:
The integrated chassis structure provides self-aligning and self-securing features through the board resting portions that are built into the chassis body. The PCB mounting structure utilizes the chassis itself to provide alignment guides, support surfaces, and retention mechanisms, eliminating the need for external fastening tools and complex assembly steps.
3Ease of operation
If a sliding mechanism is used for PCB mounting, then the ease of assembly is improved, but the structural complexity of the mounting portion increases
Solution Approach 1:
The patent segments the mounting interface into distinct functional elements: board resting portions for support and alignment, guide protrusions for positioning, and stopper structures for final location. These segmented features are integrated into the chassis body and work together to enable easy sliding assembly while distributing the structural requirements across multiple simple, well-defined elements rather than a single complex mechanism.
