Safety Seat Buckle Positioning for Faster Harness Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety seats with multipoint harness buckling systems are inefficient in securing a person due to inconvenient placement of buckles and harness straps, requiring unnecessary steps and causing discomfort or injury during the securing process.
Innovation Solution
The advanced safety seat buckling system involves reversible fastening of buckle ends to slots on the armrests and the use of retractor cords to position buckles away from the backrest, allowing for easier and quicker securing of individuals by storing harness components out of the seating area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If buckles and harness straps are placed on the backrest of the safety seat, then the harness can secure the person, but the securing process becomes tedious and time-consuming
Solution Approach 1:
The buckle is pre-positioned on the armrest in an easily accessible location before the person needs to be secured. This preliminary placement eliminates the need to manually move the buckle from the backrest area, allowing the user to simply connect the strap to the pre-positioned buckle, thus reducing the time and complexity of the securing process while maintaining secure fastening
2Device complexity
If shoulder harnesses are rested against the backrest, then the harness structure is simple, but the placement is inconvenient and causes discomfort or injury
Solution Approach 1:
The invention transitions the buckle placement from the vertical backrest dimension to the horizontal armrest dimension. This dimensional change positions the buckle laterally within easy reach of the person being secured, eliminating the need to reach behind or manipulate straps in awkward positions, thereby improving ease of operation while keeping the overall harness structure relatively simple
3Loss of time
If buckles are placed on the armrest slots, then the securing time is reduced, but the armrest structure becomes more complex
Solution Approach 1:
The armrest slot serves multiple functions: it provides structural support for the armrest, enables adjustable positioning of the buckle at different locations along the armrest, and facilitates quick connection and disconnection of the harness. By making the armrest slot multi-functional, the design achieves rapid securing capability without requiring entirely separate complex mechanisms, thus minimizing the increase in overall device complexity

AI summary
An improved safety seat buckling system and method of using the same for facilitating placement of a person into a safety seat is disclosed. A series of slots or fasteners placed on the armrest of the safety seat are fitted to interface with the buckle male end portions of the harness assembly. By placing each buckle male end portion into the corresponding slot, placement of a person into the seat prior to securing the person into the seat becomes easier. Less time is required to secure the person into the safety seat, and the need for the person to lean forward while securing the person into the seat is eliminated.
