Solution Overview

Problem

Conventional infant carrier apparatuses, such as strollers, are often bulky due to their need for both forward and rearward seating configurations, which increases their size and makes them less convenient for use.

Innovation Solution

An infant carrier apparatus with a backrest assembly that is adjustable along a longitudinal axis via holder sockets and restraint elements, allowing the backrest to be positioned adjacent to either the front or rear end of the seat assembly, enabling forward or rearward seating configurations without requiring a larger seat area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the stroller has both forward and rearward seating configurations with separate seat portions, then the seating versatility is improved, but the overall size of the stroller increases

Engineering Contradiction:

Improveseating configuration versatilityVSAvoidstroller size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The backrest assembly is made dynamically adjustable along the longitudinal axis of the seat assembly through holder sockets positioned at multiple locations. This allows the backrest to be repositioned between a first position for forward-facing seating and a second position for rearward-facing seating, enabling versatile seating configurations without requiring separate fixed seat portions for each orientation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The single seat assembly is designed to perform multiple seating functions by adjusting the backrest position. The holder socket mechanism enables the same physical seat to accommodate both forward-facing and rearward-facing configurations, making one seat structure universal for multiple seating orientations rather than requiring separate specialized seats.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the backrest is adjustable along the longitudinal axis via holder sockets, then the seating orientation flexibility is improved, but the device complexity increases

Engineering Contradiction:

Improveseating orientation flexibilityVSAvoidbackrest adjustment mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The backrest adjustment mechanism is segmented into discrete components: the backrest assembly, the holder socket with multiple positioning locations, and restraint elements. This segmentation allows each component to perform a specific function independently, making the overall system easier to manufacture, assemble, and maintain while still achieving versatile seating orientations.
