Connector Voltage Detection for Modular Electronic Device Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices, such as tablets and smartphones, face challenges in accommodating diverse user requirements due to size and cost constraints, making it inconvenient to replace or expand function modules internally.
Innovation Solution
An electronic device with a connector system that determines electrical connection and power supply to external devices based on voltage levels, using processing circuits and power switching circuits to manage power distribution and communication via I2C interfaces, allowing for functional expansion through detachable modules like backplanes, batteries, or speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If function modules are configured inside portable electronic devices, then device functionality is improved, but device size and cost increase
Solution Approach 1:
The patent divides the electronic device into a main body and detachable function modules. The connector enables these modules to be separated and reattached, allowing functionality to be segmented into discrete units that can be configured externally rather than integrated internally, thus reducing device size while maintaining adaptability.
Solution Approach 2:
The connector is designed as a universal interface that can accommodate multiple different function modules. This single connector structure provides multi-functionality by supporting various detachable modules (such as cameras, batteries, or audio devices), eliminating the need for separate internal configurations for each function.
2Adaptability or versatility
If function modules are configured inside portable electronic devices, then device functionality is improved, but ease of replacement deteriorates
Solution Approach 1:
By segmenting the device into a main body and detachable modules connected via a connector, the patent enables easy replacement of function modules. Users can simply detach and reattach modules without complex internal disassembly, significantly improving ease of replacement while maintaining functional versatility.
3Adaptability or versatility
If function modules are configured inside portable electronic devices, then device functionality is improved, but cost increases
Solution Approach 1:
The universal connector design allows a single interface structure to support multiple function modules. This reduces manufacturing costs by eliminating the need for separate internal configurations for each function, as all modules connect through the same standardized interface, simplifying production while maintaining versatility.
