Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging solutions for electronic devices lack a convenient and efficient mechanism for extending and retracting charging interfaces, such as USB ports or electrical prongs, which limits user convenience and compatibility with different power sources.
Innovation Solution
A charging apparatus featuring a sliding tray with a grooved track and gear assembly that allows the charging interface to be extended and retracted, combined with a stabilizer tray for weight support, enabling easy deployment and storage of the charging interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed charging interface is used, then the structure is simple, but the adaptability to different power sources and user convenience deteriorates
Solution Approach 1:
The charging interface is implemented as a dynamic, movable component rather than a fixed element. The sliding tray mechanism allows the charging interface to extend and retract based on usage needs, transforming a static structure into a dynamic one that adapts to different charging scenarios and power source configurations.
Solution Approach 2:
The charging case is divided into functional segments: a stationary housing, a movable sliding tray, and a deployable charging interface. This segmentation allows the charging interface to be independently positioned and extended only when needed, providing versatility while maintaining structural simplicity when not in use.
2Ease of operation
If a movable charging interface is implemented, then user convenience and adaptability improve, but the device complexity increases
Solution Approach 1:
The sliding tray mechanism is designed to be manually operable by the user without requiring complex motors or automated systems. The user can easily slide the tray in and out to deploy or store the charging interface, making the system self-serving and simple to operate despite the added functionality.
Solution Approach 2:
The sliding tray acts as an intermediary mechanism between the stationary charging case housing and the deployable charging interface. This intermediate component simplifies the overall mechanism by providing a straightforward sliding motion that connects the fixed structure to the movable interface, reducing the need for complex linkages or actuation systems.
3Stability of the object's composition
If a stabilizer tray is added for weight support, then the stability improves, but the device complexity increases
Solution Approach 1:
The stabilizer tray is merged with the sliding tray mechanism, combining the stabilization function with the existing movable tray structure. This integration allows the same component to serve dual purposes: supporting the charging interface during extension and providing weight support when deployed, thereby reducing overall structural complexity.
Solution Approach 2:
The stabilizer tray is designed as a multi-functional component that serves both as a structural support element and as part of the sliding mechanism. When the sliding tray is extended, the stabilizer tray provides weight support; when retracted, it integrates seamlessly into the charging case structure, demonstrating universal functionality that reduces the need for separate stabilization components.
