PCB Reinforcement Around USB Interface for Slimmer Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices face durability issues with their USB connecting interfaces due to repeated attachment and detachment of external connectors, leading to potential damage and increased thickness when using separate durability reinforcement structures.
Innovation Solution
An electronic device design featuring a reinforcement member on the printed circuit board surrounding the USB connecting interface without covering its top surface, applied in a surface-mounted device (SMD) type to enhance durability and reduce thickness by providing a stable shielding effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate mechanical durability reinforcement structure is used to surround the USB connecting interface, then the durability of the connecting interface is improved, but the thickness of the portable electronic device increases
Solution Approach 1:
The reinforcement structure is merged with the PCB by directly forming it on the PCB surface using conductive material. This integration eliminates the need for separate mechanical reinforcement elements and their associated mounting structures, thereby preventing thickness increase while maintaining durability enhancement at the USB connecting interface
Solution Approach 2:
The patent replaces traditional mechanical reinforcement structures (such as metal brackets or protective frames) with a conductive pattern formed directly on the PCB. This substitution uses the PCB's inherent structural properties and conductive material deposition to provide both mechanical support and electromagnetic shielding, eliminating the need for additional mechanical components that would increase device thickness
2Strength
If a durability reinforcement structure attached by separate tape is used, then the strength of the connecting interface is improved, but the structure may be damaged by impact applied to it
Solution Approach 1:
The reinforcement structure is merged with the PCB by directly forming it on the PCB surface using conductive material. This integration eliminates the need for separate mechanical reinforcement elements and their associated mounting structures, thereby preventing thickness increase while maintaining durability enhancement at the USB connecting interface
Solution Approach 2:
The reinforcement structure is pre-formed as part of the PCB manufacturing process through conductive material deposition. This preliminary formation ensures the reinforcement structure is inherently bonded to the PCB substrate, providing impact resistance from the outset rather than relying on separate attachment methods that may fail under impact conditions
