Adjustable Bracket Mechanism for Wireless Charger Height Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless chargers for portable electronic devices, particularly those designed for vertical placement, face challenges in accommodating devices of varying sizes due to fixed support frame heights, which limits compatibility with different electronic products.
Innovation Solution
A wireless charger with a releasably connected elongated bracket featuring adjustable portions that can be slid relative to a housing, allowing for adjustable height settings through a mechanism involving a button member and spring mechanism, enabling the charger to fit devices of different sizes by locking the bracket at user-selected heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed support frame height is used in vertical placement wireless chargers, then the structural simplicity is maintained, but the adaptability to different electronic device sizes is reduced
Solution Approach 1:
The support frame transitions from a fixed structure to a dynamically adjustable one. The bracket is designed to be slidable along the support frame, allowing users to adjust the height position according to different device sizes. This dynamic adjustment mechanism resolves the contradiction by enabling adaptability while maintaining relatively simple structural composition.
Solution Approach 2:
The support frame is segmented into adjustable sections with multiple first adjustment portions positioned at different heights. The bracket can engage with different segments to achieve various height positions. This segmentation allows the structure to adapt to different device sizes while keeping each segment relatively simple in design.
2Adaptability or versatility
If an adjustable bracket mechanism is added to enable height adjustment, then the adaptability to different device sizes is improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism incorporates a spring member that automatically pushes the bracket when the button member is released. This self-service feature eliminates the need for complex motorized or manually operated adjustment systems, reducing overall device complexity while maintaining adjustability functionality.
Solution Approach 2:
The button member acts as an intermediary control element that simplifies the adjustment operation. By pressing the button, users can easily engage or disengage the bracket from different adjustment portions without dealing with complex mechanisms. This intermediary element masks the complexity of the underlying spring and engagement system.
3Stability of the object's composition
If a releasable locking mechanism is implemented to secure the bracket at adjusted positions, then the stability of the charging position is improved, but the ease of operation for adjustment is reduced
Solution Approach 1:
The locking function is extracted into a separate button member that can be independently operated. When the button is pressed, it releases the locking engagement between the bracket and the adjustment portions, allowing easy movement. When released, the spring automatically restores the locking position. This extraction separates the adjustment and locking functions, improving both stability and ease of operation.
Solution Approach 2:
The spring member is pre-loaded to automatically engage the bracket with the nearest adjustment portion when the button is released. This preliminary action ensures the bracket is quickly and securely locked into position without requiring additional user effort, maintaining ease of operation while ensuring stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable mechanism allows the wireless charger to support devices of various sizes by allowing the charging component to be positioned at multiple heights, enhancing compatibility and usability across different electronic devices.
Implementation Method 1
a button member having a spring member is abutted against the fixing plate. The button member has a pressing portion and is also connected to or integral to the second adjustment portion, wherein when the pressing portion is pressed, the second adjustment portion is displaced to disengage a corresponding one of the first adjustment portions from the second adjustment portion while the spring member is simultaneously compressed against the fixing plate.

AI summary
A wireless charger having a base, an adjustable bracket and a housing slidably connected to the bracket, with the base being releasably connected to the bracket. In some embodiments, the wireless charger includes a button member that can be displaced to move a connector plate and in turn, compress a spring member, in order to disengage a locking member from the bracket so that the bracket can be slidably adjusted relative to the housing.
