Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless charging apparatuses have a complex moving mechanism that often results in the induction coil getting stuck, failing to provide full coverage due to inconsistent output speeds of moving components.
Innovation Solution
A wireless charging apparatus with a dual drive assembly system, where the first drive assembly provides rotational motion and the second drive assembly allows for linear motion of the charging coil, ensuring comprehensive coverage and preventing jamming through a cooperative motion mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If two linear modules are used to enable the induction coil to move in the X and Y directions, then the induction coil can achieve full coverage, but the linear motion structure becomes complex and the moving components may get stuck
Solution Approach 1:
The patent divides the motion system into two independent drive assemblies: a first drive assembly for X-direction motion and a second drive assembly for Y-direction motion. Each assembly operates independently with its own driving components, avoiding the complexity and interference of a single integrated two-axis mechanism. This segmentation allows each module to be simpler and more reliable while achieving comprehensive coverage when combined.
Solution Approach 2:
The patent transitions from using two linear modules in the same plane to using one linear module (second drive assembly) and one rotary module (first drive assembly) operating in different dimensional orientations. The rotary module provides motion in one dimension while the linear module provides motion in another dimension, reducing structural complexity and preventing jamming between components.
2Area of stationary object
If two linear modules are used to enable the induction coil to move in the X and Y directions, then the induction coil can achieve full coverage, but the moving components may get stuck due to inconsistent output speeds
Solution Approach 1:
By segmenting the motion control into two independent drive assemblies with separate driving sources, the patent eliminates the speed synchronization problem that occurs when two linear modules are mechanically coupled. Each assembly can operate at its own optimal speed without causing the other to stall or jam, significantly improving reliability.
Solution Approach 2:
The patent uses a rotary module for one axis and a linear module for the other axis, operating them in different dimensional spaces. This dimensional separation prevents mechanical interference and speed inconsistency issues that arise when two linear modules attempt to operate in the same plane, thereby enhancing the reliability of the motion mechanism.
