Solution Overview
Problem
Existing charging adapters for blinds and electric curtains with DC batteries face issues such as easy plug misalignment, wear, and damage due to the thin power cord and cumbersome plug connections, which are prone to errors and wear during use and maintenance.
Innovation Solution
A charging adapter with magnetic plug connectors that ensure correct alignment and secure connection of the power supply to the battery, using a flexible power cord with magnetic plugs to facilitate easy and stable connection, reducing wear and misalignment risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a thin power cord with small plugs is used to connect the power supply to the battery, then the device can be made compact and flexible, but the connection becomes prone to misalignment, wear, and damage
Solution Approach 1:
The patent replaces the traditional mechanical plug-and-socket connection system with a magnetic connection system. The magnetic connector uses magnetic attraction forces to automatically align and secure the connection between the power supply and battery, eliminating the need for manual alignment and reducing wear from repeated插拔 operations. This substitution of mechanical alignment with magnetic field guidance resolves the contradiction by making connections both easy (automatic alignment) and reliable (secure magnetic hold).
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the power supply connector and battery connector. This magnetic field acts as a mediator that guides the connectors into proper alignment and maintains a secure connection without direct mechanical contact until the final engagement. The magnetic intermediary eliminates the need for precise manual positioning while ensuring reliable connection, thereby resolving the contradiction between ease of operation and connection reliability.
2Reliability
If traditional plugs are used for charging connection, then the electrical connection can be established, but the plugs are difficult to position and lock correctly, and are susceptible to wear from many connections
Solution Approach 1:
The magnetic connector system is self-aligning and self-latching through magnetic attraction. When brought into proximity, the magnetic fields automatically guide the connectors into correct alignment and secure the connection without requiring manual positioning or locking mechanisms. This self-service capability eliminates the difficulty of plug positioning while ensuring stable, repeatable connections, resolving the contradiction between reliability and ease of operation.
3Device complexity
If a thin power cord is used for charging, then the adapter can be compact, but the power cord is easily torn over and susceptible to damage during maintenance and cleaning operations
Solution Approach 1:
The magnetic connector creates a pre-engaged, secure connection that resists external forces before any damage can occur to the cord. The magnetic attraction force acts as a preliminary securing mechanism that prevents the cord from being torn or damaged during maintenance and cleaning operations. This preliminary magnetic locking protects the thin power cord from mechanical damage while maintaining device compactness, resolving the contradiction between cord thickness and strength.

Function Achieved in This Case
The magnetic plug system ensures correct and secure connection, preventing damage and wear, making the charging process more efficient and reliable by maintaining proper alignment and easy disconnection under varying forces.
Implementation Method 1
The two plugs 36 and 46 simply connect and align through magnetic forces, which magnetic forces hold and force the two plugs 36 and 42 to stay correctly connected together.
