Portable Wireless Charger Cradle Telescopic Nesting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable wireless charging devices face issues with transportability and the risk of losing detachable components, which compromises their functionality and user convenience, especially when used in scenarios requiring portability and safety against unexpected impacts.
Innovation Solution
A portable wireless charging device design where both the cradle support member and target support member are integrated to revolve around the charging body, eliminating protrusions and allowing for secure fastening when folded, and incorporating a hinging mechanism with auxiliary rotors and backlashing stopping units to prevent element loss and ensure safety against external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the target support member is detached from the charging body to increase portability, then transportability is improved, but the risk of losing the component increases and functionality is compromised
Solution Approach 1:
The target support member is nested within the charging body through a telescopic structure, allowing it to be stored inside the charging body when not in use. This eliminates the need for detachment while maintaining compact form factor and preventing loss of the component.
Solution Approach 2:
The target support member and charging body are merged into a single integrated unit through the telescopic mechanism. The member can extend from and retract into the charging body, combining the functionality of both components while eliminating the risk of separation and loss.
2Length of moving object
If the cradle support member and target support member are folded to enhance transportability, then the device becomes more portable, but the structure becomes more complex
Solution Approach 1:
The support members are designed with telescopic and rotating capabilities, allowing them to dynamically adjust between extended and retracted positions. This dynamic structure enables compact folding for portability while maintaining structural integrity through controlled movement mechanisms.
Solution Approach 2:
The cradle support member and target support member are designed to nest within each other or within the charging body when folded. This nesting arrangement reduces the overall volume for transport while maintaining a relatively simple structural configuration compared to traditional foldable mechanisms.
3Reliability
If the target support member protrudes from the charging body to maintain functionality, then charging capability is preserved, but transportability deteriorates
Solution Approach 1:
The target support member is designed to be extendable from the charging body when needed for charging operations, and retractable when not in use. This dynamic extension and retraction capability allows the device to maintain full charging functionality while achieving a compact profile for transport.
Solution Approach 2:
The target support member can be nested inside the charging body when not in use, eliminating the protrusion that would hinder transportability. The member can be extended from the charging body when charging functionality is required, thus resolving the contradiction between maintaining functionality and improving transportability.

AI summary
A portable apparatus can be used for a wireless charging operation. The portable apparatus includes a charging body including a transmitter configured to send a power signal for a charging operation, a first rotating member supporting a charging target, and a second rotating member supporting the charging body. Herein, the first rotating member and the second rotating member revolve around the charging body in a predetermined direction, but move within different rotating angles.
