Wireless Charging Stand With Retractable Bracket for Flat Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charging devices have a fixed bracket that protrudes in both horizontal and vertical states, limiting the placement of electronic devices and affecting the flatness and convenience of the charging surface.
Innovation Solution
A charging device with a movable bracket that switches between a protruding and received state, allowing it to be flush with the housing in the horizontal state and protrude in the vertical state, enabled by a transmission member and motor assembly that drive the second housing to rotate and translate relative to the first housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bracket protrudes in both horizontal and vertical states, then the electronic device can be securely positioned in vertical state, but the flatness of the charging surface is reduced and placement flexibility is limited
Solution Approach 1:
The bracket is designed to be movable rather than fixed, allowing it to change position between protruding and received states. The motor assembly drives the bracket to protrude when the electronic device is in vertical state for secure positioning, and to retract when in horizontal state to maintain flatness, thus dynamically adapting to different usage scenarios
Solution Approach 2:
The position parameter of the bracket is changed based on the state of the electronic device. By controlling the bracket's extension distance through the motor assembly, the system adjusts the bracket's position to either protrude (for vertical state support) or retract (for horizontal state flatness), optimizing performance for each state
2Reliability
If the bracket is fixed and always protruding, then vertical state positioning is secure, but the convenience of placing electronic devices in horizontal state is affected
Solution Approach 1:
The bracket transitions from a fixed structure to a dynamic one that can adjust its position. The motor assembly enables the bracket to move between protruding and received states, making the charging device adaptable to different placement scenarios and improving ease of operation for both horizontal and vertical states
3Reliability
If the bracket protrudes continuously, then vertical state support is maintained, but the overall size and compactness of the charging device is reduced
Solution Approach 1:
The bracket is designed to nest within the housing when not in use. In horizontal state, the bracket retracts into the received state, occupying minimal space within the housing boundaries. When vertical state is detected, the bracket protrudes from the housing to provide support, thus maintaining compactness while providing extended functionality when needed

AI summary
Provided are a charging device and an electronic device assembly. The charging device includes a first housing, a second housing, a charging assembly, and a bracket. The second housing can translationally move and rotate relative to the first housing. The second housing is configured for placement of an electronic device. The charging assembly is disposed in the second housing and configured to charge the electronic device. The bracket is movable relative to the first housing and movable along with a rotation of the second housing relative to the first housing, enabling at least part of the bracket to be switched between a protruding state, in which the at least part of the bracket protrudes from the first housing or is flush with the first housing, and a received state, in which the at least part of the bracket is received in the first housing.
