Split Micro USB Port Layout for Connector Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern portable electronic devices are prone to damage when the micro USB connector is subjected to excessive force, often occurring during accidental falls or attempts to retrieve a device from a confined space.
Innovation Solution
The Connector Protection System (CPS) divides the default micro USB Female connector into two separate connections using a microchip and two micro USB Female connectors, creating distinct channels for charging and data transmission, thereby distributing the force more evenly and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the micro USB connector is used as a single integrated connector for both charging and data transmission, then the device structure remains simple, but the connector is vulnerable to damage from excessive force during falls or retrieval operations
Solution Approach 1:
The patent divides the single micro USB connector into two separate connectors: a first micro USB connector for charging and a second micro USB connector for data transmission. This segmentation allows each connector to be independently protected and reduces the risk that force applied to one connector will damage the other, thereby improving overall connector reliability while maintaining reasonable structural complexity through modular design
2Ease of operation
If the charging cable is used to retrieve the device from a confined space, then the device can be recovered, but excessive force is exerted on the connector-stem and connection-pins causing damage
Solution Approach 1:
By separating the charging and data connectors into distinct physical locations on the device, the patent enables the charging cable to be attached to one connector without transmitting excessive retrieval forces to the other connector. This segmentation protects the connection-pins and connector-stem from damage during retrieval operations while maintaining ease of device recovery
Solution Approach 2:
The patent introduces a protective case with a reinforced connector-stem structure that acts as an intermediary between the external environment and the internal connectors. This protective intermediary absorbs and distributes forces during retrieval operations, preventing direct transmission of excessive force to the vulnerable connection-pins and connector mounts
3Ease of operation
If the connector is positioned at the edge of the device for easy access, then the connector is more accessible, but it is more susceptible to impact damage when the device falls
Solution Approach 1:
The patent positions the two micro USB connectors at different locations on the device body rather than both at the same edge location. This spatial segmentation reduces the probability that a single impact event will simultaneously damage both connectors, while both connectors remain easily accessible for their respective functions
Solution Approach 2:
The protective case incorporates shock-absorbing materials and reinforced connector housings that provide beforehand cushioning to the connectors. This pre-positioned protection absorbs impact forces before they reach the vulnerable connection-pins and connector-stem, reducing damage from falls while maintaining connector accessibility
