Synchronous Stroller Unlocking Mechanism for Seat and Frame Locks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strollers require separate locking mechanisms for the seat and stroller frame, which is inconvenient and prone to damage due to complexity.
Innovation Solution
A synchronous unlocking mechanism that synchronously unlocks the seat and stroller frame using a grip, locking member, elastic member, and towing member, allowing simultaneous operation of both components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate locking mechanisms are used for the seat and stroller frame, then each component can be locked independently, but the device complexity increases and the ease of operation decreases
Solution Approach 1:
The patent combines the seat locking mechanism and stroller frame locking mechanism into a single integrated locking system. The locking member is coupled to both the seat assembly and stroller frame, allowing one locking operation to secure both components simultaneously, thereby reducing device complexity while maintaining independent locking capability through the integrated design
2Reliability
If separate locking mechanisms are used for the seat and stroller frame, then each component can be locked independently, but the ease of operation worsens as users must operate each mechanism separately
Solution Approach 1:
The patent merges the operation of two separate locking mechanisms into a single unified operation. The grip is coupled to the locking member which simultaneously controls both seat locking and frame locking, allowing users to unlock both components with one action, significantly improving ease of operation while maintaining the reliability of independent locking through the coupled design
3Reliability
If multiple locking mechanisms are used in the stroller, then comprehensive locking coverage is achieved, but the device complexity increases and reliability decreases due to more potential failure points
Solution Approach 1:
The patent merges multiple locking mechanisms into a single integrated locking system that provides comprehensive locking coverage. The locking member is simultaneously coupled to the seat assembly and stroller frame, creating one unified mechanism that secures both components, thereby reducing the number of potential failure points while maintaining comprehensive locking coverage
4Reliability
If multiple locking mechanisms are used in the stroller, then comprehensive locking coverage is achieved, but the ease of operation worsens and the device is more prone to damage
Solution Approach 1:
The patent merges multiple locking mechanisms into a single integrated system that provides comprehensive locking coverage. The grip is coupled to the locking member which simultaneously controls both seat and frame locking, allowing users to unlock both components with one simple action, thereby improving ease of operation while maintaining comprehensive locking coverage and reducing the complexity that leads to damage
