Detachable Connector Linkage for Controlled Attachment Powering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face issues where the tablet terminal and keyboard unit may become energized before or after detachment, leading to potential electrical connections that are not fully controlled.
Innovation Solution
The device incorporates a lock mechanism that fixes the tablet terminal to a socket, a connector holder shift mechanism, and a link mechanism to ensure complete fixation and controlled electrical connection between units, allowing the second connector to engage only after full fixation and disengage before release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connector is provided to enable electrical connection between detachable units, then the functionality and adaptability of the electronic device is improved, but the risk of unintended energization before complete fixation increases
Solution Approach 1:
The lock mechanism is activated before the connector engages. The fixing unit secures the first unit to the second unit in the attachment direction, establishing mechanical fixation prior to electrical connection. This preliminary mechanical securing ensures that the units are firmly attached before any electrical energization occurs, preventing unintended power states during the attachment process.
Solution Approach 2:
The attachment system is divided into separate functional components: a lock mechanism for mechanical fixation and a connector for electrical connection. These are implemented as distinct units that operate in a specific sequence, allowing independent control of mechanical and electrical engagement. The connector is positioned such that it engages only after the lock mechanism has completed fixation, ensuring reliable controlled connection.
2Device complexity
If a simple socket structure is used for detachable attachment, then the device complexity is reduced, but the precision of fixation and timing of electrical connection deteriorates
Solution Approach 1:
The lock mechanism performs preliminary mechanical fixation by securing the first unit to the second unit before the connector engages. This preliminary action ensures that the units are firmly attached and positioned correctly before electrical connection occurs, achieving precise fixation timing without requiring complex simultaneous coordination mechanisms.
Solution Approach 2:
The fixing unit acts as an intermediary mechanism between the simple socket structure and the connector. It mediates the attachment process by first establishing mechanical fixation, then enabling the connector to engage. This intermediary step ensures precise fixation completion before electrical connection, maintaining manufacturing precision while keeping the overall structure relatively simple.
