Safety Seat Base Support Foot Indicator for Quiet Installation Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety seat bases with support feet have indicating structures that are inconvenient to view and generate noise due to relative shaking between components, potentially leading to improper assembly and safety hazards.
Innovation Solution
A safety seat base design that rotates an indicating member by rotating the support foot, featuring a frame with an indicating window and a protruding portion to align color blocks visibly, and includes a torsion spring and elastic sheet to ensure proper assembly, with optional alarm devices for confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the indicating structure is disposed at the bottom of the support foot, then the structure is simple, but it is inconvenient for users to see the indication
Solution Approach 1:
The patent moves the indicating structure from the bottom (horizontal position) to the top (vertical position) of the support foot, changing its spatial dimension. This allows users to see the indication easily without complicating the overall structure, as the indicating member simply rotates into view within the existing indicating window on the base body.
2Ease of operation
If the indicating structure is disposed on the top of the support foot, then it is convenient for users to see, but relative shaking between components generates noise
Solution Approach 1:
The patent merges the indicating member with the support foot by making the indicating member an integral part of the support foot structure. The indicating member is formed as one piece with the support foot, eliminating relative shaking and noise generation while maintaining easy visibility from the top position.
Solution Approach 2:
The patent introduces a rotating connection mechanism as an intermediary between the support foot and the indicating member. This allows the indicating member to rotate independently with the support foot, absorbing movement and preventing direct transmission of shaking and noise to the base body.
3Reliability
If the support foot is unfolded incompletely, then the safety seat base may not be properly installed, but there is no warning to alert users
Solution Approach 1:
The patent implements a feedback mechanism where the indicating member provides visual feedback about the support foot's unfolding status. When the support foot is completely unfolded, the indicating member rotates to show a first color block in the indicating window; when incompletely unfolded, it shows a second color block or no color block, alerting users to the improper installation status.
Solution Approach 2:
The patent uses color blocks on the indicating member to provide visual alerts about installation status. Different colors indicate different states: a first color block indicates complete unfolding (proper installation), while a second color block or absence of the first color block indicates incomplete unfolding (improper installation), making the status immediately visible to users.
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
Ensures easy visibility of assembly status without noise, prevents incomplete unfolding, and alerts users through alarm devices, ensuring safe and complete installation.
Implementation Method 1
the safety seat base further includes a torsion spring, two ends of the torsion spring respectively abut against the support foot and the frame, and the torsion spring biases the support foot toward the unfolded position
Implementation Method 2
the safety seat base further includes an elastic sheet, the elastic sheet is disposed on the frame, and the elastic sheet restrains the support foot from rotating toward the unfolded position

AI summary
A safety seat base includes a base body, an indicating member and a support foot. The base body includes a frame. The frame has an indicating window. The indicating member is rotatably connected to the frame. The indicating member has a first color block. The support foot is rotatably connected to the frame. The support foot a protruding portion. When the support foot rotates to an unfolded position, the protruding portion pushes the indicating member to rotate upward, such that the indicating window shows the first color block.
