Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data lines cannot charge both Android and Apple mobile phones due to their specific charging interfaces, leading to the need for multiple charging lines and environmental concerns from excessive plastic production.
Innovation Solution
A charging apparatus with a bidirectional switching circuit that includes a T-shaped connector housing with integrated Type-C and Lightning interfaces, a chip, and a transfer switch, allowing the same data line to charge both Android and Apple devices by selectively connecting power supply pins and resistive elements to the appropriate interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate data lines are used for Type-C and Lightning interfaces, then each interface can be optimized for its specific charging requirements, but users need to carry multiple charging lines which increases device complexity and environmental impact
Solution Approach 1:
The patent combines Type-C and Lightning interface circuits into a single data line by integrating bidirectional switching circuits that can route power and data signals to either interface type, allowing one physical cable to support multiple charging standards
Solution Approach 2:
The data line is designed with universal functionality to support both Type-C and Lightning interfaces through integrated switching circuits and control chips that can dynamically adapt the connection based on the detected device type, making a single cable multi-functional
2Adaptability or versatility
If a bidirectional switching circuit is integrated into the connector housing, then a single data line can charge both Android and Apple devices, but the connector housing structure becomes more complex with additional components
Solution Approach 1:
The bidirectional switching circuit, control chip, and associated components are nested within the connector housing structure, with the switching circuit integrated into the housing and the control chip positioned to manage the switching operations, creating a compact multi-functional unit
Solution Approach 2:
The control chip acts as an intermediary between the bidirectional switching circuit and the external device, detecting the device type and controlling the switching circuit to establish the appropriate connection, while the switching circuit itself serves as an intermediary to route signals between different interface contacts
