Seat Cushion Pad Multi-Layer Assembly for Ventilation Duct Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat designs face issues with the firm combination of multiple parts in the seat pad and the duct coming off the connecting member, leading to potential separation and instability.
Innovation Solution
The seat design incorporates a configuration where the pad body, first cover member, and second cover member are fixed together, and a connecting member with flanges is used to secure the duct, ensuring the duct remains attached and the seat parts are firmly combined.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat pad is constructed with multiple separate parts (slab layers bonded to cushion pad body), then the ventilation function and structural flexibility are improved, but the parts are prone to separate and peel off from each other
Solution Approach 1:
The seat pad is divided into multiple functional parts: cushion pad body, front slab layer, and back slab layer. Each part performs specific functions (support, ventilation, comfort) while maintaining structural independence for easier manufacturing and assembly.
Solution Approach 2:
Protruding portions are pre-formed on the cushion pad body before assembly, and corresponding recessed portions are formed on the slab layers. These preliminary structural features enable automatic positioning and firm combination when the parts are assembled together.
2Ease of operation
If the duct is connected to the seat pad through a tubular insert member, then the air flow passage is established, but the duct may come off the connecting member
Solution Approach 1:
The tubular insert member is inserted into the duct, creating a nested structure where the insert member is contained within the duct. This nested configuration establishes the air flow passage while maintaining a compact connection structure.
Solution Approach 2:
The tubular insert member is pre-positioned within the duct before final assembly, and the duct is designed with features that prevent it from coming off the insert member. This preliminary positioning ensures reliable connection while maintaining ease of air flow establishment.

AI summary
A seat comprises a seat cushion pad (20) including an air flow passage (21), and a blower connected to the air flow passage (21). The seat cushion pad (20) comprises a pad body (100), and a cover member (200) disposed on an upper surface of the pad body (100) to form the air flow passage (21) between the pad body (100) and the cover member (200). The cover member (200) comprises a first cover member (210) disposed on the upper surface of the pad body (100), and a second cover member (220) disposed on an upper surface of the first cover member (210). The first cover member (210) is fixed to the pad body (100), and the second cover member (220) is fixed to the first cover member (210) and to the pad body (100).
