Seat with ventilative property
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilative seats with three-dimensional network cushion elements suffer from permanent downward settling due to weight, leading to reduced ventilation effectiveness, deformation, and a short lifespan.
Innovation Solution
The seat features independent left and right three-dimensional network cushion elements within the urethane foam padding, penetrating from the upper to lower surface, with a base portion and urethane foam impregnation layer to maintain structural integrity and prevent deformation, ensuring effective ventilation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a three-dimensional network cushion element is disposed to occupy a substantive forward region of the seat cushion, then ventilation effectiveness is improved, but the cushion element becomes permanently deformed and settled due to repeated weight application
Solution Approach 1:
The invention divides the single large three-dimensional network cushion element into multiple smaller network cushion elements arranged in a matrix pattern. This segmentation reduces the load bearing responsibility of each individual element, preventing permanent deformation while collectively maintaining effective ventilation across the forward region of the seat cushion.
2Object-affected harmful factors
If a three-dimensional network cushion element is used for ventilation, then sweaty state prevention is improved, but the shape of the seat cushion is deformed downwardly
Solution Approach 1:
The matrix arrangement of multiple small network cushion elements distributes the occupant's weight across numerous independent units. This segmentation prevents concentrated loading that causes downward deformation, while the collective ventilation effect of all elements continues to prevent sweaty states effectively.
Solution Approach 2:
The invention merges multiple small network cushion elements into a unified matrix structure that functions as a single ventilation system. This combination maintains the overall cushion shape by distributing loads, while the integrated matrix continues to provide comprehensive humidity reduction and sweaty state prevention.

AI summary
To provide a seat with ventilative property, which can eliminate or minimize the possibility of its being permanently deformed and settled into an unrecoverable deformed state. In the seat with ventilative property, left and right three-dimensional network cushion elements are provided in a forwardly-facing region of a seat cushion of the seat, in a manner independent of each other, such that the left and right three-dimensional network cushion elements are respectively situated at: one location on which a left thigh portion of a seat occupant is to be contacted; and the other location on which a right thigh portion of the seat occupant is to be contacted. This arrangement can almost completely prevent a direct application of a weight of the seat occupant to the two three-dimensional network cushion elements. Therefore, the present invention has the effect that a permanent downward settling of the seat cushion SC can be prevented, so that a short life of the seat due to such permanent settling may be substantially avoided.
