Power Interface Arc Sections for Mobile Terminal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power interfaces in mobile terminals are prone to impurities and wear, leading to unstable connections and reduced performance, affecting both charging and data transmission, and their external location impacts the device's appearance and market competitiveness.
Innovation Solution
A power interface design featuring a housing with a perimeter wall including arc sections and straight sections, which enhances stability and reliability by providing a smooth transition for connectors, improves dustproof and waterproof performance, and includes stopping plates to secure the connection body, along with expanded power pins for increased current load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connectors are frequently inserted into and removed from the power interface, then data transmission and charging functions are achieved, but the connection body becomes loose and connection stability deteriorates
Solution Approach 1:
The perimeter wall includes arc sections at two ends that are spaced apart from each other in a length direction, forming a curved structure that provides a smooth transition for the connector. This curved design reduces mechanical stress and wear during frequent insertion and removal operations, thereby maintaining connection stability while enabling charging and data transmission functions.
2Ease of operation
If the power interface is disposed at the outer side of the mobile terminal for easy access, then charging operation is convenient, but the appearance of the mobile terminal is affected and market competitiveness decreases
Solution Approach 1:
The arc sections in the perimeter wall provide a smooth, curved transition that improves the aesthetic appearance of the power interface while maintaining its external accessibility. This curved design integrates better with the overall device appearance, reducing the visual impact of having the interface at the outer side while preserving charging convenience.
3Ease of manufacture
If the power interface structure is simplified for easy manufacture, then production cost decreases, but dustproof and waterproof performance deteriorates
Solution Approach 1:
The arc sections form a curved perimeter wall structure that naturally reduces gaps and crevices where dust and water could penetrate. This curved design provides better sealing performance compared to sharp corners, improving dustproof and waterproof protection while maintaining manufacturing simplicity through a unified perimeter wall structure.
