Wireless Power Holder with Rotating Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless power transmission devices face issues with visibility of electronic device screens due to their design, which obstructs the view and also suffer from inefficient charging when mounted incorrectly, limiting the ability to adjust the viewing angle without separating the device from the holder.
Innovation Solution
A wireless power transmission device with a holder that can be set to a predetermined angle relative to the bottom surface without removing the electronic device, using a connector system with rotating pivots and cams to maintain the angle, ensuring the screen is visible and charging efficiency is maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a PAD-type wireless power transmission device is disposed to make contact with a bottom surface, then the device structure is simple, but the screen visibility is obstructed when the electronic device is mounted on the upper surface
Solution Approach 1:
The holder is designed to be rotatable relative to the base, allowing dynamic adjustment of the holder's angle. This enables the screen to be oriented at different angles for optimal visibility while maintaining the wireless charging function, resolving the contradiction between simple structure and screen visibility.
2Adaptability or versatility
If a mount-type wireless power transmission device is manufactured to be disposed in a height direction, then the device can be mounted in various orientations, but the charging efficiency deteriorates when mounted in a width direction
Solution Approach 1:
The holder can be rotated to different angles relative to the base, allowing the electronic device to be positioned at optimal orientations for charging efficiency regardless of how the base is mounted. This dynamic adjustment capability maintains charging efficiency while providing mounting versatility.
3Device complexity
If the holder angle is fixed during manufacturing, then the device structure is simple, but the viewing angle cannot be adjusted without separating the electronic device from the holder
Solution Approach 1:
The holder is designed with rotational capability relative to the base, allowing users to adjust the viewing angle by rotating the holder while the electronic device remains mounted. This provides angle adjustment functionality without increasing structural complexity or requiring device removal.
