Solution Overview

Problem

Existing seat designs with air flow passages and blowers face issues of the seat pad components separating and the duct disconnecting from the connecting member, leading to instability and discomfort.

Innovation Solution

A seat design featuring a seat pad with a cover member system that securely fixes multiple parts together, and a tubular connecting member with stopper portions to prevent duct disconnection, ensuring stability and improved seating comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a seat pad is constructed with multiple parts (slab layers bonded to cushion pad body), then the air flow passage can be formed, but the parts are prone to separate and peel off when the slab layer deforms

Engineering Contradiction:

Improveair flow passage formationVSAvoidpart separation resistance

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies the merging principle by integrating the cover member with the pad body through fixed connections. The cover member is securely attached to the pad body, forming a unified structure that prevents separation while maintaining the air flow passage functionality. This resolves the contradiction by combining previously separate parts into a stable integrated assembly.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If the duct is connected to the seat pad through an insert member, then air flow can be established, but the duct may come off the connecting member

Engineering Contradiction:

Improveair flow establishmentVSAvoidduct connection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies the nested doll principle by having the duct inserted into the connecting member, creating a nested configuration where the duct is housed within the connecting member structure. This nested arrangement provides mechanical stability and prevents the duct from disconnecting, while still allowing air flow to pass through the nested structures.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Ease of operation

If the slab layer deforms to be recessed at the central portion, then it adapts to occupant sitting, but the end portion separates from the cushion pad body

Engineering Contradiction:

Improveoccupant comfort adaptationVSAvoidend portion separation

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent applies segmentation by dividing the seat pad structure into distinct components (pad body, cover member, slab layers) that can independently deform and adapt to occupant pressure. The cover member is segmented from the pad body but connected through fixed portions, allowing the central portion to recess for comfort while the fixed connections prevent end portion separation.

Inventive Principle:

Principle #1Segmentation

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).
