Quick-Detachable Infant Bath Seat With Single-Hand Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infant bath seats often require two-handed operation for locking, leaving no hand free to hold the infant, and have inconvenient water drainage, increasing the risk of pinching injuries and making cleaning difficult.
Innovation Solution
A quick-detachable and lockable infant bath seat with a dual-locking mechanism using a limiting armrest and elliptical locking box, allowing single-handed operation and secure locking, combined with efficient drainage features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional locking mechanism requiring two-handed operation is used, then the locking function is achieved, but the ease of operation deteriorates and safety risks increase
Solution Approach 1:
The locking block is designed to automatically engage with the lock hole through elastic resetting after the limiting armrest rotates into position. The elastic member pushes the locking block to automatically lock into the lock hole, making the locking mechanism self-activating without requiring manual intervention beyond the initial rotation action.
Solution Approach 2:
The elastic member is pre-loaded to store elastic potential energy that automatically drives the locking block into the lock hole once the limiting armrest reaches its positioned state. This preliminary energy storage ensures immediate and reliable locking action without requiring additional manual steps.
2Ease of operation
If a bucket-shaped structure is used for the bath seat, then the bathing space is formed, but the ease of operation deteriorates due to inconvenient cleaning
Solution Approach 1:
The bath seat is divided into separable components including the seat assembly, backrest seat, and limiting armrest with locking mechanism. This segmentation allows the components to be disassembled for easy cleaning of water accumulation areas, particularly enabling access to previously enclosed spaces where water could stagnate.
3Ease of operation
If the locking block slides without constraint, then the ease of operation improves, but the reliability deteriorates due to potential misalignment
Solution Approach 1:
The outer end wall of the locking block is designed with an arc shape that corresponds to the curvature of the accommodating groove. This curved geometry guides the locking block smoothly along its sliding path and ensures proper alignment with the lock hole during engagement, combining ease of movement with reliable positioning.
Solution Approach 2:
The elastic member acts as an intermediary between the locking block and the accommodating groove wall. It provides controlled elastic force that guides the locking block's movement while ensuring firm engagement with the lock hole, mediating between free movement and precise positioning.

Function Achieved in This Case
Facilitates safe and convenient bathing by enabling single-handed locking and efficient water drainage, reducing the risk of pinching injuries and simplifying cleaning.
Implementation Method 1
a reset elastic member arranged between the locking block and an inner wall of the accommodating groove, providing the locking block with an elastic force that tends to insert the locking tongue into the lock hole

AI summary
The present disclosure relates to a quick-detachable and lockable infant bath seat, comprising a seat assembly, with a middle post and a backrest seat connected to the front end and rear end of the seat assembly respectively. An elliptical locking box is mounted at the top of the middle post, and a limiting armrest is rotatably connected to the top of the backrest seat. A temperature sensing meter is snapped onto the top of the elliptical locking box, and accommodating grooves are provided on both left and right ends of the elliptical locking box. Slidable locking blocks are arranged within the accommodating grooves, and the outer end walls of the locking blocks are arc-shaped.
