Highchair Socket Cover Design for Tool-Free Booster Stool 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 for sockets on the building block table, which are pressed down by the booster stool's legs, allowing smooth ascension and descension, eliminating the need to remove covers when connecting or disconnecting the booster stool, and utilizing springs for easy cover return to their original position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover is screwed to the building block table, then the socket is covered when the booster stool is removed, but the connection structure becomes complicated and the cover needs to be repeatedly installed and removed
Solution Approach 1:
The patent extracts the cover from the fixed screwed connection and makes it an independent movable component. The cover is no longer permanently attached to the building block table but can freely move along the socket, achieving aesthetic coverage when needed while simplifying the connection structure.
Solution Approach 2:
The patent transforms the static screwed cover into a dynamic movable cover that can ascend and descend along the socket. The cover moves dynamically between covering the socket (when booster stool is removed) and being pushed down (when booster stool is installed), eliminating the need for repeated installation and removal.
2Reliability
If the cover is screwed to the building block table, then the socket is covered, but the cover needs to be removed and reinstalled each time the booster stool is connected or disconnected
Solution Approach 1:
The patent makes the cover a dynamic component that automatically moves between covered and exposed positions. When the booster stool is installed, the leg pushes the cover down; when removed, the cover ascends to cover the socket. This eliminates manual installation and removal operations.
Solution Approach 2:
The cover serves itself by automatically moving to the appropriate position based on whether the booster stool is installed. The system uses the weight and position of the booster stool leg to automatically control the cover's movement, eliminating the need for user intervention.
3Ease of operation
If a movable cover design is used, then the connection process is simplified, but additional components like springs and elastic pieces are required
Solution Approach 1:
The patent merges multiple functions into the cover component: it serves as both a cosmetic cover and a connection indicator. The elastic pieces and springs are integrated into the socket and cover structures, with the elastic pieces embedded in the socket and springs connected to the cover's movement mechanism, reducing the perception of additional separate components.
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 design simplifies the connection process by allowing the booster stool to press down covers, enabling convenient assembly and disassembly without requiring cover removal, enhancing usability and aesthetics.

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.
