Bassinet Double-Lock Mechanism to Prevent Accidental Mode Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multipurpose bassinets have a single-lock function for the rotating device, which is prone to misoperation, especially by babies, posing a safety hazard when converting between crib and cradle modes.
Innovation Solution
A safe bassinet design featuring left and right support frames with bending rods, sliders, and fixed blocks, equipped with separation and swing buttons that require a double-lock function to ensure safe operation, preventing accidental conversion between crib and cradle modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-lock function is used for the rotating device, then the device complexity is reduced and ease of operation is improved, but safety and reliability deteriorate due to prone misoperation
Solution Approach 1:
The patent applies preliminary action by requiring the user to perform a sequence of actions (pressing separation button first, then swing button) before the rotating device can be operated. This preliminary separation step ensures intentional operation and prevents accidental activation, directly addressing the safety concern while maintaining operational ease through clear button guidance
2Reliability
If a double-lock mechanism is implemented, then safety and reliability are improved by preventing misoperation, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the locking mechanism into two distinct functional components: a separation button mechanism and a swing button mechanism. Each button handles a specific aspect of the operation (separation mode vs. swing mode), which reduces the complexity of each individual component while achieving the overall safety goal through their coordinated operation
3Reliability
If a double-lock mechanism is implemented, then safety is improved, but ease of operation deteriorates due to more complex operation steps
Solution Approach 1:
The patent applies dynamics by making the operational requirements adaptive to the desired mode. The system dynamically adjusts its locking behavior based on which mode is selected: in separation mode, only the separation button needs to be pressed; in swing mode, both separation and swing buttons must be pressed. This dynamic approach maintains safety while optimizing ease of operation for each specific use case
