Display Frame PCB Holder Structure for Variable Source Board Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing source PCB fixing structures are designed for specific sizes, requiring redesign when the size of the source PCB changes, and they do not accommodate cables of varying lengths, leading to potential damage and increased thickness in display devices.
Innovation Solution
A display device with a frame that includes a rib and a holder structure, allowing for detachable coupling of source PCBs and cables of various sizes and lengths, enhancing rigidity and minimizing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size source PCB fixing structure is used, then the structure is simple and easy to manufacture, but it cannot accommodate source PCBs of various sizes and cables of various lengths
Solution Approach 1:
The fixing structure is divided into separate functional components: a holder for mounting the source PCB and a separate reinforcing rib. This segmentation allows the holder to be designed for universal compatibility while the rib provides structural support, enabling adaptation to various PCB sizes without redesigning the entire structure.
Solution Approach 2:
The holder is designed with a universal mounting interface that can accommodate source PCBs of different sizes and cables of different lengths. By making the holder multi-functional, a single design serves multiple purposes across different product specifications, eliminating the need for size-specific fixing structures.
2Ease of operation
If a rigid fixed-size fixing structure is used, then the structural strength is high, but it cannot be easily adjusted for different sizes and may cause damage
Solution Approach 1:
The fixing structure transitions from a completely rigid design to a semi-rigid design by introducing a detachable holder that can be coupled and decoupled. This dynamic element allows for easy installation and removal while the reinforcing rib maintains structural integrity, reducing the risk of damage during operations.
3Productivity
If a traditional source PCB fixing structure is used, then the manufacturing cost is low, but redesign is required when source PCB size changes
Solution Approach 1:
The holder is designed as a universal component that can mount source PCBs of various sizes without requiring redesign. This universal design enables the same fixing structure to be used across different product models and specifications, significantly improving production efficiency by eliminating repeated redesign cycles.
4Strength
If a source PCB fixing structure is added, then the source PCB is securely mounted, but the thickness of the display device increases
Solution Approach 1:
The holder and reinforcing rib are designed to nest within the existing frame structure of the display device. By integrating the fixing components into the available space rather than adding external protrusions, the mounting security is achieved while minimizing the increase in overall device thickness.
