Solution Overview

Problem

The existing electrical connection methods for motor vehicle accessories, such as power steering devices, are prone to blind connections due to cramped access areas, leading to a high risk of disconnection, especially when the vehicle is in motion, which can be dangerous for the driver.

Innovation Solution

An arrangement featuring a support with a U-shaped housing and extension plate positioned under the steering column, allowing for easy access and visual verification of the power and signal connectors, ensuring a secure and robust connection by keeping the connectors protected from external interference and foot contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the power connector and signal connector are systematically assembled and locked by an operator in a cramped area under the steering column, then the electrical connection can be established, but the risk of blind connection increases and the connectors may not be properly connected, leading to disconnection

Engineering Contradiction:
Improveease of assemblyVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent relocates the connector assembly location from a cramped area under the steering column to a more accessible position on the steering column housing. This spatial repositioning allows operators to easily access and visually verify connector assembly while maintaining secure electrical connections for the power-assisted steering device.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the connectors are positioned in a cramped area under the steering column, then the electrical connection can be made, but the access for assembly, control, or maintenance operations becomes difficult

Engineering Contradiction:
Improveconnection stabilityVSAvoidaccessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the connectors from the cramped area under the steering column and repositions them on the steering column housing where they are more accessible. This separation allows operators to easily reach and visually inspect the connectors while the power-assisted steering device remains functional.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If the connectors are exposed to the external environment in a cramped area, then assembly is possible, but the risk of external interference and foot contact increases, leading to potential disconnection

Engineering Contradiction:
Improveassembly simplicityVSAvoidexternal interference
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent employs the steering column housing structure to enclose and protect the connectors from external environmental factors and foot contact. The housing acts as a protective barrier while allowing accessible assembly and maintenance operations.

Inventive Principle:
Principle #30Flexible shells and thin films
