Solution Overview
Problem
The integration of wireless charging into a mouse pad is hindered by the difficulty of forming multiple grooves on a single substrate, which is necessary for magnetic resonance-based charging, making it challenging to arrange surrounding rings of a coil side by side.
Innovation Solution
A flexible wireless charging mouse pad design featuring a single-ring groove on a flexible board layer with a coil module composed of surrounding rings arranged side by side, adhered by a double-sided adhesive layer, simplifying the manufacturing process and reducing material requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If magnetic resonance principle is used for wireless charging, then high transmission efficiency is achieved, but multiple grooves must be formed on the substrate which increases manufacturing difficulty
Solution Approach 1:
The coil is divided into multiple surrounding rings that are arranged side by side, with each ring being an independent conductive element. This segmentation allows the coil to achieve magnetic resonance wireless charging functionality while avoiding the need to form multiple complex grooves on the substrate, as the segmented rings can be more easily manufactured and assembled.
2Adaptability or versatility
If multiple grooves are formed on the substrate to accommodate coil surrounding rings, then wireless charging function is integrated, but the process becomes very difficult and costly
Solution Approach 1:
The surrounding rings of the coil are arranged in the lateral direction (horizontal arrangement) rather than requiring vertical stacking or complex three-dimensional groove structures. This dimensional reorganization allows multiple rings to be accommodated on a flat substrate without requiring multiple deep grooves, significantly simplifying the manufacturing process while maintaining wireless charging functionality.
3Ease of manufacture
If surrounding rings are arranged side by side, then manufacturing is simplified, but magnetic resonance wireless charging cannot be achieved with traditional single-coil design
Solution Approach 1:
Multiple surrounding rings are electrically connected in series or parallel to form a unified coil structure that functions as a single magnetic resonance system. The double-sided adhesive layer ensures reliable electrical connections between adjacent rings, merging their individual magnetic fields into a coherent resonant system that achieves effective wireless charging despite the distributed arrangement of rings.

AI summary
A flexible wireless charging mouse pad includes an anti-slip cushion layer, a double-sided adhesive layer, and a coil. The anti-slip cushion layer has a topside with a single-ring groove, and the single-ring groove has an inner bottom groove wall. The double-sided adhesive layer is adhered to the topside. The coil has multiple surrounding rings arranged side by side with one another to form a coil module, and the coil module of the coil inside the single-ring groove is stacked and connected between the double-sided adhesive layer and the inner bottom groove wall and adhered by the double-sided adhesive layer, so as to achieve a wireless charging effect by the mouse pad in the condition of having only one single-ring groove on the flexible board layer, further to achieve the effects of reducing manufacturing difficulty, lowering manufacturing cost, and improving market competitiveness.
