Rotatable Charging Cover Adapts to Varying Terminal Slot Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery-charging bases are not adaptable to portable information terminals with varying lengths and widths, and their battery-charging slots are often positioned differently, making it difficult to connect and disconnect charging plugs without applying excessive force, which can damage the connectors.
Innovation Solution
A battery-charging base with a rotatable battery-charging cover that can house and support different types of portable information terminals by adjusting its housing position, featuring a first rotation axis and stopper ribs to limit the rotation range and ensure easy connection and disconnection, and an extensible holding member to accommodate larger devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-position battery-charging slot is provided in the holding base, then the structure is simple, but it cannot adapt to portable information terminals with different battery-charging slot positions
Solution Approach 1:
The battery-charging plug connector is made movable through a rotatable cover structure. The cover can rotate about a rotation axis to adjust the position of the battery-charging plug connector, enabling adaptation to different battery-charging slot positions on various terminal types while maintaining a relatively simple overall structure.
Solution Approach 2:
The holding base is designed to accommodate multiple types of portable information terminals (smartphones, tablets, etc.) with different sizes and battery-charging slot positions. The rotatable cover mechanism provides universal adaptability across different terminal types without requiring multiple dedicated charging bases.
2Ease of operation
If excessive force is applied to connect or disconnect the battery-charging plug connector, then connection is achieved, but the connector may be damaged
Solution Approach 1:
The rotatable cover structure allows the battery-charging plug connector to move dynamically to match the battery-charging slot position. This dynamic adjustment eliminates the need for excessive force during connection, as the connector naturally aligns with the slot through rotation rather than forced insertion.
Solution Approach 2:
The rotation mechanism pre-adjusts the position of the battery-charging plug connector before connection occurs. By preliminarily positioning the connector at the correct location through rotation, the actual connection process requires minimal force, preventing connector damage.
3Adaptability or versatility
If the battery-charging plug connector position is fixed, then the structure is stable, but it cannot accommodate terminals with varying battery-charging slot positions
Solution Approach 1:
The cover structure provides controlled movement through rotation about a fixed rotation axis. This dynamic element allows the battery-charging plug connector to adapt to different slot positions while the rotation axis itself remains stable and fixed, maintaining overall structural stability during operation.
Solution Approach 2:
Instead of moving the connector in multiple directions, the design uses rotational movement in a single dimension (angular displacement) to achieve positional adaptation. This one-dimensional rotational degree of freedom simplifies the mechanism while effectively accommodating various slot positions.
4Adaptability or versatility
If a rotatable cover structure is added to adjust connector position, then adaptability to different terminals is improved, but device complexity increases
Solution Approach 1:
A single rotation axis with a rotatable cover provides the necessary adaptability through one degree of freedom. This dynamic element is simpler than alternative solutions that might require multiple actuators, motors, or complex mechanical linkages to achieve the same positional adjustment capability.
Solution Approach 2:
The design solves the positional adaptation problem using rotational movement rather than linear translation or multi-axis movement. This approach reduces the complexity of the mechanical structure while achieving effective adaptation to different terminal types and slot positions.
