Pause-Function Unlocking Mechanism for One-Handed Seat Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby safety seat unlocking mechanisms require simultaneous pressing of both releasing buttons with two hands, which is inconvenient for users carrying other items when detaching the seat from a stroller.
Innovation Solution
An unlocking device with a pause function that includes a housing, releasing member, first moving member, second moving member, and third moving member, allowing the user to press one releasing member first and then the other, or press both simultaneously before moving their hands away, enabling the user to lift the safety seat without continuous two-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional unlocking mechanism requires simultaneous pressing of both releasing buttons, then the safety and reliability of the unlocking mechanism is improved, but the ease of operation deteriorates when the user carries other items
Solution Approach 1:
The patent applies preliminary action by introducing a pause function that temporarily maintains the unlocking state after one button is pressed. The releasing member remains in the released position for a predetermined time period, allowing the user to prepare for detachment without needing to press both buttons simultaneously. This resolves the contradiction by enabling safe unlocking (reliability) while accommodating users carrying items (ease of operation).
Solution Approach 2:
The patent applies dynamics by making the unlocking mechanism adaptable through the pause function. The system dynamically transitions between locked and unlocked states with a controllable intermediate pause state. The releasing member can be held in the released position temporarily, then automatically returns to the original position if not operated within the predetermined time. This dynamic behavior allows the mechanism to be both safe (automatic return) and convenient (temporary hold).

AI summary
An unlocking device with a pause function comprises a first moving member having a first protruding portion, a second moving member having a second protruding portion, and a third moving member having a third end portion and a fourth end portion. The second moving member is disposed corresponding to the first moving member. The second protruding portion is disposed cooperated with the first protruding portion. The third end portion is connected to the second moving member. When the fourth end portion of the third moving member contacts a carry body, and a first end portion of a releasing member moves along a first direction towards the housing, the releasing member drives the first moving member to move in the first direction, so the second moving member holds the position of the releasing member by the second protruding portion and the first protruding portion.
