Synchronous Stroller Unlocking Mechanism for One-Step Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strollers require multiple, locking mechanisms for synchronously unlocking and folding multiple locking mechanisms, which are complicated and costly, and existing strollers have separate locking mechanisms for the seat and frame, making them inconvenient and prone to damage.
Innovation Solution
A synchronous unlocking mechanism that integrates a grip, locking member, elastic member, and towing member to simultaneously unlock the seat and frame, reducing the number of components and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate locking mechanisms are used for the seat and stroller frame, then the locking function is reliable, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent merges the seat locking mechanism and stroller frame locking mechanism into a single integrated locking mechanism. The locking member simultaneously engages with both the seat and stroller frame, allowing both components to be locked or unlocked together through a single operation, thereby reducing device complexity while maintaining reliability
Solution Approach 2:
The locking member is designed to perform multiple functions: it locks both the seat and stroller frame simultaneously, and can also serve as a releasing member when pulled by the towing member. This multi-functionality reduces the need for separate mechanisms while ensuring reliable locking of both components
2Reliability
If separate locking mechanisms are used for the seat and stroller frame, then the locking function is reliable, but the ease of operation deteriorates as users need to operate each mechanism separately
Solution Approach 1:
The patent combines multiple locking operations into a single action. When the releasing member is pulled, it simultaneously unlocks both the seat and stroller frame through the towing member, allowing users to fold the entire stroller with one operation rather than separately unlocking each component
Solution Approach 2:
The elastic member is pre-loaded to store energy that automatically acts on the locking member when the releasing member is pulled. This preliminary energy storage enables the simultaneous unlocking of both seat and frame without requiring additional user effort, improving operational convenience
3Reliability
If multiple locking mechanisms are used, then the locking coverage is complete, but the device complexity increases and reliability deteriorates due to more components that can be damaged
Solution Approach 1:
The patent consolidates multiple locking mechanisms into a single integrated system where one locking member controls both the seat and stroller frame locking. This reduces the total number of components that can fail while maintaining complete locking coverage of both critical components
Solution Approach 2:
The locking member is designed as a universal component that can lock both the seat and stroller frame, reducing component diversity and the associated failure points. The single locking member performs multiple locking functions, thereby reducing overall system complexity while maintaining comprehensive locking coverage
4Reliability
If multiple locking mechanisms are used, then the locking coverage is complete, but the ease of operation deteriorates as users need to operate each mechanism separately
Solution Approach 1:
The patent merges multiple unlocking steps into a single operation. By integrating the seat and frame locking mechanisms, the system allows users to unlock both components simultaneously by operating one releasing member, eliminating the need for sequential unlocking operations
Solution Approach 2:
The elastic member is pre-loaded with energy that is automatically released when the releasing member is pulled, enabling simultaneous unlocking of both seat and frame without requiring multiple user actions. This preliminary energy storage simplifies the operation to a single step while maintaining complete unlocking coverage
