Charging Terminal Protrusion Control for Mounting Catch Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charging apparatuses face difficulties in mounting portable devices due to the risk of the charging terminal becoming caught by the device during shifting, making it challenging to securely connect and charge portable apparatuses.
Innovation Solution
The charging apparatus incorporates a dual movable member system where the first movable member protrudes and is pressed down by the portable device, while the second movable member accommodates and protrudes the charging terminal, with controlled movement and angular adjustments to minimize the risk of catching, ensuring proper contact with the charge-receiving terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging terminal protrudes in accordance with the mounting of the portable apparatus, then the charging terminal can contact the charge-receiving terminal, but the charging terminal may become caught by the portable apparatus making it difficult to mount
Solution Approach 1:
The charging terminal is designed with movable members that allow dynamic adjustment of its protrusion amount. The first movable member protrudes and is pressed down by mounting the portable apparatus, while the second movable member accommodates and protrudes the charging terminal. This dynamic configuration enables the charging terminal to adapt its position based on mounting status, ensuring contact reliability while preventing catching during the mounting process.
Solution Approach 2:
The patent controls the movement parameters of the charging terminal by configuring the movable members such that the amount of movement during the intermediate state is smaller than the amount of movement during the terminal contact state. This parameter control ensures that the charging terminal moves gradually and predictably, reducing the risk of catching while maintaining reliable contact when mounted.
2Reliability
If the charging terminal moves proportionally to the pressing down amount of the first movable member, then the terminal contact state is achieved, but the charging terminal may become caught during the intermediate state
Solution Approach 1:
The system transitions from a simple proportional movement relationship to a dynamic, multi-stage movement control. The movable members are configured to create an intermediate state where the charging terminal moves less than proportionally, preventing catching while still progressing toward the terminal contact state. This dynamic control resolves the contradiction between achieving contact and avoiding harmful catching effects.
Solution Approach 2:
The patent implements a cushioning effect by designing the movable members to reduce the movement amount of the charging terminal during the intermediate state. This beforehand cushioning prevents the charging terminal from moving too quickly or too far during mounting, reducing the risk of catching before the final contact state is achieved.

AI summary
An example of a charging apparatus includes a housing, a first movable member, and a second movable member. The first movable member is configured to be pressed down. The second movable member accommodates a charging terminal in the housing in a reference state, and when the first movable member has been pressed down, causes the charging terminal to protrude through an opening portion provided in the housing, so as to enter a terminal contact state. The first movable member and the second movable member are configured such that an amount of movement of the charging terminal during a period from the reference state to a predetermined intermediate state is smaller than the amount of movement during the same period in a case where the charging terminal moves from the reference state to the terminal contact state by an amount proportional to an amount of pressing down the first movable member.
