Vehicle Seat Ventilation Structure for Stable Airflow and Softness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seats lack effective ventilation, leading to discomfort due to sweat buildup during summer driving, and existing ventilation structures either compromise on performance or increase manufacturing costs, while also potentially making the seat feel less soft due to foreign body sensations.
Innovation Solution
A vehicle seat design featuring a seat pad with pad holes, a mesh sheet with a porous network structure, and a first film with holes, arranged sequentially to maintain stable air passages, using flexible but incompressible materials to prevent compression and enhance airflow, with optional additional films and structures to adjust blowing performance and positions at low cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate structure is inserted into the seat pad to form air passages, then blowing performance and adjustability are improved, but the user feels a foreign body sensation decreasing seat softness
Solution Approach 1:
The air passage structure is merged with the mesh sheet itself rather than being a separate inserted component. The mesh sheet serves dual functions as both the structural element and the air passage medium, eliminating the foreign body sensation while maintaining blowing performance.
Solution Approach 2:
The mesh sheet acts as a flexible thin film that integrates air passages into the seat pad structure. This flexible membrane approach allows air flow without creating rigid foreign objects that would reduce seat softness or cause discomfort.
2Reliability
If the mesh sheet has a porous network structure, then air flow is improved, but the structural integrity may be compromised
Solution Approach 1:
The mesh sheet utilizes a porous network structure that provides adequate air flow paths while maintaining sufficient structural integrity. The porous design allows air permeability without compromising the strength needed to support user weight and maintain seat shape.
Solution Approach 2:
The mesh sheet is constructed as a composite structure combining materials with different properties to achieve both porosity for air flow and strength for structural integrity. The composite nature allows optimization of both airflow characteristics and mechanical strength.

AI summary
A vehicle seat for cooling and heating may include a seat pad, a mesh sheet having a certain thickness, a first film, and a porous seat cover, which are arranged sequentially in the direction in which air is introduced to flow. The seat pad has a pad hole, which allows air to pass through, and includes one or both of a seat cushion pad, which supports the buttocks of a user, and a seatback pad, which supports the upper body of the user. The mesh sheet has a porous network structure, through which air easily passes. The first film has a first film hole, which allows air to pass through. Air passages are maintained stable to maximize blowing performance, seating comfort is improved, and a ventilation structure is simplified to reduce manufacturing costs while improving productivity.
