Solution Overview

Problem

Existing motor-vehicle dashboards struggle to accommodate air vents of the same type across different models with varying dimensions and installation spaces efficiently, lacking flexibility, simplicity, and reliability in mounting solutions.

Innovation Solution

A motor-vehicle dashboard with a shaped support body and a positioning adapter body that includes a ring-shaped flange with fastening and support elements, allowing air vents of the same type to be mounted on dashboards with different dimensions and installation spaces, ensuring strength and reliability through a rigid connection and snap mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a standardized vent design is used across different motor-vehicle models, then manufacturing cost and inventory complexity are reduced, but the ability to accommodate different dashboard dimensions and installation spaces is worsened

Engineering Contradiction:
Improvemanufacturing costVSAvoidadaptability to different dashboard dimensions
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The mounting system is divided into two segments: a universal vent unit and a model-specific positioning adapter body. The adapter body is customized for each dashboard type while the vent unit remains standardized, allowing the same vent to be installed on different dashboard models through the intermediary adapter component.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The positioning adapter body serves as an intermediary component between the standardized vent unit and the diverse dashboard structures. It translates the universal mounting interface of the vent into model-specific mounting patterns, enabling compatibility across different vehicle models without modifying the vent design.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple custom vent designs are created for different dashboard models, then fit and integration are improved, but manufacturing cost and complexity increase

Engineering Contradiction:
Improvefit to dashboardVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system separates the vent unit (produced once in standardized design) from the positioning adapter body (produced in model-specific variants). This segmentation allows the majority of the product line to use a single vent design while only the smaller adapter components need customization for each model.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized vent unit is designed with universal mounting features that can work with any positioning adapter body in the series. This multi-functionality allows a single vent design to serve multiple dashboard models when paired with the appropriate adapter, reducing the total number of unique vent designs needed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If simple mounting mechanisms are used, then ease of installation is improved, but reliability and strength of connection under airbag activation forces are worsened

Engineering Contradiction:
Improveease of installationVSAvoidconnection strength
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The positioning adapter body pre-establishes precise alignment and positioning features (such as locating pins and guide surfaces) before the final fastening step. This preliminary action ensures that the vent unit is correctly positioned and that fastening elements engage with optimized force distribution, achieving both easy installation and strong connection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The positioning adapter body is made from high-strength plastic material that combines ease of injection molding with sufficient mechanical strength to withstand airbag activation forces. This material selection allows the adapter to provide both installation convenience and structural reliability.

Inventive Principle:
Principle #40Composite materials
