Supporting Leg Indicator Assembly for Floor Contact Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats are prone to overturning during vehicle accidents, making it difficult for users to verify if the supporting leg device has contacted the vehicle floor without leaning over, which compromises safety.
Innovation Solution
An indicator assembly for the supporting leg device featuring a pivotally accommodated indicating member with different color or pattern areas, driven by elastic and pushing members, allowing the user to visually confirm contact with the floor without leaning over, through an indicator window on the supporting leg device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the supporting leg device is installed on the base of the child safety seat and supported on the floor of the vehicle, then the anti-overturning and anti-impact capability of the child safety seat is enhanced, but it becomes inconvenient for the user to check whether the supporting leg device has touched the floor of the vehicle
Solution Approach 1:
The patent introduces an indicator assembly as an intermediary element between the supporting leg device and the user. This indicator assembly includes an indicating member with different color areas that visually communicates whether the supporting leg has contacted the vehicle floor, eliminating the need for the user to physically lean over and check the contact status while maintaining the structural function of the supporting leg device
Solution Approach 2:
The indicator assembly provides visual feedback to the user about the contact status of the supporting leg device. The indicating member changes its displayed color area based on whether the supporting leg is contacting the floor or not, giving the user immediate information about the installation state without requiring physical inspection

AI summary
An indicator assembly of a supporting leg device for a safety seat and a safety seat are provided. The indicator assembly includes an indicator housing having an indicator window; an indicating member including a first area and a second area adjacent to each other; a first elastic member for pivoting the indicating member to a first position in a first direction such that the first area is exposed from the indicator window; a pushing member, a top end of which pushing the indicating member to pivot to a second position in a second direction; a driving member including an upper end provided with an engaging hook and a lower end capable of touching a floor, in which the engaging hook can be engaged into the engaging hole of the pushing member; when the lower end of the driving member touches the floor, the driving member drives the pushing member to move upward, thereby pushing the indicating member to pivot to a second position in the second direction, so that the second area is exposed from the indicator window. According to the indicator assembly of the present disclosure, a user can observe whether the supporting leg device touches the floor of a vehicle without leaning over.
