Solution Overview

Problem

Conventional vehicle seats require additional parts like drive mechanisms and recliner cores to adjust the seat cushion and seatback, increasing manufacturing costs and weight, which negatively impact fuel efficiency and user convenience.

Innovation Solution

A vehicle seat design featuring guide pins and brackets that allow the seat cushion and seatback to recline and slide together without separate driver parts, enabling easy assembly and disassembly, and tipping-up functionality, thereby reducing complexity and weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate drive parts and recliner cores are applied to adjust the seat cushion and seatback, then the seat can be freely adjusted, but the manufacturing cost and weight of the vehicle seat increase

Engineering Contradiction:

Improveseat adjustment capabilityVSAvoidvehicle seat weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent combines the drive part and recliner core functions into an integrated mechanism where the seatback bracket serves dual purposes: supporting the seatback and providing the drive mechanism for both seatback reclining and seat cushion tipping. This merging eliminates separate components while maintaining full adjustment capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The seatback bracket is designed as a multi-functional component that simultaneously supports the seatback, enables reclining motion through guide pin interaction, and controls seat cushion tipping. This universal component replaces multiple specialized parts, reducing overall system weight.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate drive parts and recliner cores are applied to adjust the seat cushion and seatback, then the seat can be freely adjusted, but the manufacturing cost of the vehicle increases

Engineering Contradiction:

Improveseat adjustment capabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts and eliminates unnecessary intermediate components from the conventional seat adjustment system. By removing separate drive parts and recliner cores, the design achieves simpler manufacturing processes and lower production costs while retaining essential adjustment functions.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If separate drive parts and recliner cores are applied to adjust the seat cushion and seatback, then the seat can be freely adjusted, but the weight of the vehicle seat increases to reduce fuel efficiency

Engineering Contradiction:

Improveseat adjustment capabilityVSAvoidfuel efficiency

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Weight of moving object

If a simplified structure without separate drive parts is used, then the manufacturing cost and weight are reduced, but the seat adjustment functionality must be maintained

Engineering Contradiction:

Improvevehicle seat weightVSAvoidseat adjustment capability

Core Design Contradiction:

Weight of moving objectVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The guide pin acts as an intermediary element that mediates between the seatback bracket and the seat cushion bracket, enabling coordinated motion between the seatback reclining and seat cushion tipping without requiring separate drive mechanisms for each function.

Inventive Principle:

Principle #24Intermediary (Mediator)

5Volume of moving object

If the seat cushion and seatback are removably provided, then the inside space utilization of the vehicle is improved, but the assembly and disassembly process must be simplified

Engineering Contradiction:

Improveinside space utilizationVSAvoidassembly complexity

Core Design Contradiction:

Volume of moving objectVSEase of manufacture

Solution Approach 1:

The patent extracts the seat cushion and seatback as removable components from the fixed seat structure. This allows the seat components to be taken out when not needed, maximizing the vehicle's inside space utilization for cargo or other purposes.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The guide pin and locking portion mechanism serves as an intermediary system that simplifies the connection and disconnection processes. The guide pin aligns the components during assembly, while the locking portions provide easy engagement and release, making the removable design practical for users.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A seat for a vehicle is proposed. The seat for a vehicle is configured to perform sliding of a seat cushion in conjunction with reclining of a seatback without a separate driver part or recliner, and to realize tipping-up of the seat cushion with the seat cushion and the seatback removably provided, and to be easily mounted and assembled to a vehicle to secure the inside space utilization of the vehicle and achieve cost reduction.
