Electric Shaver Magnetic Mounting for Stable Charging Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engaging structures for electric shavers and chargers often experience loose contact issues, leading to unsatisfactory electrical connections and instability during mounting, despite previous attempts to improve terminal contact mechanisms.
Innovation Solution
The proposed solution involves a magnet and an attracting member made of magnetically attracted material on one of the electric shaver or charger, with contact points positioned between the weight center and magnet, ensuring stable contact pressure and precise positioning through a combination of magnetic and horizontal attractive forces, along with multi-point benders and a detector unit for accurate mounting detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If charging pins are positioned at the lower portion of the electric shaver, then the height of the cleaning/charging apparatus can be reduced, but loose contact between terminals occurs
Solution Approach 1:
The magnet is positioned above the contact point at an opposite side of the mounting direction, creating a preliminary magnetic attraction force that pulls the electric shaver toward the charger before physical contact is made. This preliminary action ensures the contact portions are already aligned and pressed together with sufficient force when mounting occurs, preventing loose contact while allowing the charger to maintain a compact height.
2Reliability
If magnet is positioned above contact point, then stable contact pressure is achieved, but positioning precision must be maintained
Solution Approach 1:
The magnet is deliberately positioned asymmetrically above the contact point rather than directly above it, at an opposite side of the mounting direction. This asymmetric positioning creates a magnetic attraction force that has both a vertical component (providing contact pressure) and a horizontal component (guiding the shaver into precise positioning). The attracting member is positioned to work with this asymmetric magnet arrangement, ensuring both stable contact pressure and accurate alignment.
