Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in aligning wireless charging devices with charging pads due to the obscure location of receiving coils and the device's size obstructing the view of the alignment area, leading to unpredictable and unreliable charging processes.
Innovation Solution
Incorporating software that generates assistive visuals and hardware sensors, such as auxiliary wire windings, to detect proximity and alignment with the charging pad, providing visual indicators like arrows or graphical overlays to guide proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the device size is increased to provide a larger display area, then the user interface can be more comprehensive, but the user's view of the alignment area on the charging pad is obstructed
Solution Approach 1:
The patent introduces an intermediary solution by projecting alignment indicators onto the charging pad surface or displaying them through the device screen. This intermediary visual guidance system mediates between the large device display area and the need for clear alignment area visibility, allowing users to see alignment markers without directly viewing the charging pad surface.
2Ease of manufacture
If the receiving coil location is not made obvious, then the device design remains simple, but users cannot accurately align the device with the charging pad
Solution Approach 1:
The patent applies visual indicators that change color or appear in specific colors to indicate the receiving coil location and alignment status. These colored indicators (such as green, yellow, red zones) make the invisible coil location obvious to users without complicating the physical device design, thereby maintaining manufacturing simplicity while improving alignment accuracy.
3Device complexity
If no alignment assistance is provided, then the system remains simple, but the charging alignment process becomes unpredictable and unreliable
Solution Approach 1:
The patent implements a feedback mechanism where the device detects its position relative to the charging pad and provides real-time visual feedback through alignment indicators. This feedback loop guides users to adjust device placement, transforming the unreliable manual alignment process into a reliable guided alignment process without significantly increasing system complexity.
