Car Seat Dual-Connection Release Handle for Base and Stroller Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current car seat designs require different connection mechanisms for securing to strollers and car seat bases, necessitating separate control mechanisms, which is inconvenient.
Innovation Solution
A car seat release mechanism with a single handle-operated system that simultaneously controls both stroller and car seat base connection mechanisms, utilizing cables and springs to shift between open and closed positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control mechanisms are used for stroller and car seat base connection, then each connection can be independently controlled, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The patent combines two separate control mechanisms into a single integrated handle that simultaneously controls both the stroller connection mechanism and the car seat base connection mechanism. This merging reduces device complexity and improves ease of operation by allowing the user to secure or release both connections with a single action.
Solution Approach 2:
The single handle is designed to perform multiple functions: it operates both the stroller connection mechanism and the car seat base connection mechanism. This multi-functionality eliminates the need for separate controls and simplifies the user interface while maintaining independent control capability for each connection type.
2Ease of operation
If a single handle operates both connection mechanisms, then ease of operation improves, but the reliability of individual connection control may be compromised
Solution Approach 1:
While using a single handle for overall control, the patent maintains segmented control pathways through separate cables for each connection mechanism. The handle pulls a common cable that is connected to both the stroller connection mechanism and the car seat base connection mechanism, allowing independent operation of each connection while maintaining a unified control interface.
Solution Approach 2:
The patent introduces an intermediary cable system that transmits the force from the single handle to both connection mechanisms independently. This intermediary mechanism ensures that operating the handle reliably controls both connections without compromising the reliability of individual connection control.
