Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-contact charging efficiency in communication apparatuses is compromised due to misalignment of transmission-side and reception-side charging modules, which affects the alignment of magnetic sheets or coils, leading to deteriorated power transmission efficiency.
Innovation Solution
A communication apparatus design where the non-contact charging module and NFC antenna are housed separately, with hollow portions of their coils facing each other, preventing misalignment and enhancing magnetic flux reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the non-contact charging module and sheet antenna are stacked (overlapped), then the device structure is compact, but alignment errors occur during non-contact charging which deteriorates power transmission efficiency
Solution Approach 1:
The patent transitions from a two-dimensional stacked arrangement to a three-dimensional spatial separation arrangement. The non-contact charging module and sheet antenna are positioned at different locations within the device housing, with their coils facing each other through hollow portions, thereby eliminating alignment issues while maintaining compact overall device volume.
Solution Approach 2:
The patent divides the device into distinct functional regions: one region housing the non-contact charging module and another region housing the sheet antenna. This segmentation prevents interference between the two modules while allowing each to function optimally in its designated space.
2Ease of operation
If magnetic sheets or coils are used for aligning the transmission-side and reception-side modules, then alignment is facilitated, but misalignment with the sheet antenna still occurs causing efficiency deterioration
Solution Approach 1:
The patent introduces hollow portions in both the non-contact charging module and sheet antenna as intermediary structures. These hollow portions serve as alignment guides that naturally direct the coils toward each other, eliminating the need for magnetic sheets or coils for alignment purposes while ensuring precise positioning.
3Volume of moving object
If the non-contact charging module and sheet antenna are placed close together, then space is saved, but magnetic flux reception is hindered causing charging efficiency to drop
Solution Approach 1:
The patent creates localized optimal conditions for magnetic flux reception by positioning the coils of the non-contact charging module and sheet antenna to face each other directly through their hollow portions. This local optimization ensures efficient magnetic coupling while the overall device maintains compact dimensions through clever spatial arrangement.

AI summary
This communication apparatus makes it possible to have a non-contact charging module and a sheet antenna coexist, even in the case where there the non-contact charging module and the sheet antenna in the communication apparatus. The apparatus is provided with: a housing; a secondary-side non-contact charging module, which is housed in the housing, receives power by means of electromagnetic induction, and has a first coil having a conducting wire wound thereon, and a first magnetic sheet facing the first coil; and an NFC antenna, which is housed in the housing, and has a second coil having a conducting wire wound thereon, and a second magnetic sheet facing the second coil. The secondary-side non-contact charging module and the NFC antenna are not laminated to each other.
