Wireless Charging Cover Structure for Coil Alignment and Thin Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless charging structures in electronic devices increase thickness and processing costs, and may result in eccentricity and deformation of wireless charging coils due to separate attachment methods, which require additional processing and materials.
Innovation Solution
A wireless charging structure is integrated into the housing of an electronic device, with a wireless charging coil surrounded by an insert portion and aligned using a guide slot, molded with a thermosetting material to form a rear cover without increasing thickness or costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover member is designed to fit tightly over the sensor assembly to protect it, then protection reliability is improved, but the sensor assembly cannot be removed and reattached for replacement or adjustment
Solution Approach 1:
The cover member is divided into a first cover portion and a second cover portion that can be separated from each other. The first cover portion remains attached to the housing while the second cover portion can be detached to allow access to the sensor assembly. This segmentation enables the sensor assembly to be removed and reattached while maintaining protection when assembled, resolving the contradiction between protection reliability and replaceability.
2Device complexity
If the cover member is made as a single integrated piece to simplify structure, then device complexity is reduced, but it cannot provide both protection and easy access for sensor replacement
Solution Approach 1:
The cover member is segmented into two functional portions: a first cover portion that provides structural attachment and a second cover portion that provides removable protection. This segmentation allows the cover to simultaneously achieve protection functionality and easy access for sensor replacement without requiring a completely complex multi-component system.
Solution Approach 2:
The second cover portion is configured to fit over the sensor assembly in a nested arrangement, where the cover portion envelops the sensor assembly. This nesting relationship allows the cover portion to be easily attached and detached while maintaining a compact integrated appearance when assembled, balancing structural simplicity with functional versatility.
3Reliability
If the cover member is designed to fully enclose the sensor assembly for maximum protection, then protection reliability is improved, but the sensor assembly cannot be accessed for replacement or adjustment
Solution Approach 1:
The cover member is segmented into a fixed first cover portion and a removable second cover portion. The second cover portion can be detached from the first cover portion to provide access to the sensor assembly, while the first cover portion remains attached to maintain structural integrity and protection. This segmentation enables easy sensor replacement while maintaining protection reliability.
4Adaptability or versatility
If the cover member is designed with separation capability to allow sensor replacement, then adaptability is improved, but protection reliability may be compromised
Solution Approach 1:
The second cover portion is designed to nest over the sensor assembly and connect to the first cover portion, creating a complete enclosing structure when assembled. This nested configuration ensures that when the cover portions are connected, they provide full protection equivalent to a fully enclosed design, while still allowing separation for sensor replacement.
Solution Approach 2:
The sensor assembly is pre-configured with engagement features that align with the cover portions. When the cover portions are connected, these features automatically engage to secure the sensor assembly in place, ensuring proper positioning and protection before the cover is closed. This preliminary configuration ensures protection reliability is maintained when the cover portions are reconnected after sensor replacement.
