Highchair Socket Cover with Spring Mechanism for Tool-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing highchair designs have complicated connections that require covers to be removed and reinstalled each time the booster stool is connected or disconnected from the building block table, causing inconvenience.
Innovation Solution
The design incorporates elastic covers with spring mechanisms that automatically ascend and descend based on the weight of the booster stool and feeding chair, eliminating the need to manually remove or install covers when the booster stool is connected or removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If covers are screwed to the building block table, then the socket is covered when the booster stool is removed, but the connection structure becomes complicated and requires manual removal and reinstallation
Solution Approach 1:
The cover is transformed from a static screwed-on component to a dynamic spring-loaded component that automatically moves between covering and non-covering positions. The spring mechanism enables the cover to dynamically adapt its position based on whether the booster stool is present, eliminating the need for manual intervention and complex screw connections.
Solution Approach 2:
The cover system performs self-service by automatically covering or exposing the socket based on the presence of the booster stool. When the booster stool is installed, its weight compresses the spring and moves the cover away from the socket. When removed, the spring automatically returns the cover to its original position, eliminating the need for manual removal and reinstallation.

Solution Approach 1:
The cover system performs self-service by automatically covering or exposing the socket based on the presence of the booster stool. When the booster stool is installed, its weight compresses the spring and moves the cover away from the socket. When removed, the spring automatically returns the cover to its original position, eliminating the need for manual removal and reinstallation.
Solution Approach 2:
The spring mechanism is pre-installed and pre-positioned to automatically perform the covering action. The system is prepared in advance with the spring loaded, so that when the booster stool is removed, the cover automatically returns to its covering position without requiring any manual intervention.
3Adaptability or versatility
If the cover needs to be removed and reinstalled each time, then the socket can be accessed when needed, but convenience is reduced

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the connection process by allowing the covers to remain in place when the booster stool is connected to the building block table and automatically return to their original position when the booster stool is removed, enhancing convenience and ease of use.

AI summary
A highchair includes a building block table, a booster stool and a feeding chair. The bottom of the booster stool is detachably connected to the top of the building block table. The bottom of the feeding chair is detachably connected to the top of the booster stool. Four sockets are provided on the top surface of the building block table. An elastic cover that is adapted to the socket covers the top of each socket. A plurality of vertical grooves are spaced apart on the inner periphery of each socket. The bottom surface of each socket is provided with a first spring receiving groove. A plurality of protruding blocks are spaced apart on the outer periphery of each cover. The protruding block is matched with a corresponding groove. The bottom surface of each cover is provided with a second spring receiving groove. A first spring is provided between the first spring receiving groove and the second spring receiving groove. The booster stool has four legs, and the bottom of each of the four legs can be inserted into the corresponding socket. In the present invention, the cover is conveniently connected to the socket, and the cover does not need to be removed whether the booster stool is connected to the building block table or not.
