Tablet Protective Case With Wired Keyboard Power Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tablet computer protective cases with keyboards require additional power supply, such as extra batteries or external charging cables, increasing production costs and experiencing Bluetooth disconnection issues.
Innovation Solution
A tablet computer protective case device that allows a wired connection between the tablet and keyboard for power supply, using a conductive connecting wire and matching connectors to transmit power directly from the tablet to the keyboard, eliminating the need for additional power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If additional power supply (extra batteries or external charging cables) is installed in the keyboard, then the keyboard can be powered, but production costs increase
Solution Approach 1:
The power supply function is extracted from the keyboard and relocated to the protective case, which itself is powered by the tablet computer. This eliminates the need for separate batteries or charging cables in the keyboard, reducing production costs while maintaining power supply capability.
Solution Approach 2:
The protective case and keyboard power supply systems are merged into a single integrated solution. The case contains both the power receiving unit (connected to tablet) and power transmitting unit (connected to keyboard), combining multiple functions into one component.
2Ease of operation
If Bluetooth wireless connection is used between tablet and keyboard, then wireless operation is enabled, but connection instability and disconnections occur
Solution Approach 1:
The system dynamically switches between wireless Bluetooth connection and wired USB connection modes. When Bluetooth connection is unstable or disconnected, the system can automatically or manually switch to the wired connection through the protective case, providing dynamic adaptability to maintain reliable operation.
3Ease of manufacture
If wired connection is implemented between tablet and keyboard through protective case, then power supply cost is reduced, but device structure becomes more complex
Solution Approach 1:
The protective case is designed with multi-functionality: it provides physical protection for the tablet, serves as a power supply intermediary between tablet and keyboard, and offers a wired connection interface. By making the case universal and multi-functional, the added complexity is justified by the elimination of separate power supply components.
