Solution Overview

Problem

The installation of motor vehicle steering shafts is ergonomically undesirable, requiring operators to lie down and exert force to maneuver the shaft into position, which is inefficient and uncomfortable.

Innovation Solution

A system comprising a decking arm assembly with a support structure, actuator, cradle, and sensor assembly that supports the instrument panel, engages the steering shaft, and detects the correct installation position, allowing for ergonomic and efficient installation by moving the actuator and cradle to secure the panel in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual installation method is used, then operator can install the steering shaft, but operator must lie down and exert force which is ergonomically undesirable

Engineering Contradiction:
Improveoperator ergonomicsVSAvoidinstallation efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces manual mechanical operations with an automated mechanical system. The decking arm assembly with actuator automatically positions and secures the steering shaft, eliminating the need for operators to manually lie down and exert force, thereby resolving the ergonomic contradiction while maintaining installation efficiency

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The steering shaft assembly is designed with self-aligning features including positioning protrusions that automatically engage with corresponding recesses in the instrument panel. This self-service mechanism eliminates the need for operator intervention and physical exertion, improving ergonomics while ensuring precise installation

Inventive Principle:
Principle #25Self-service

2Ease of operation

If automated decking arm assembly is used, then operator ergonomics are improved, but device complexity increases

Engineering Contradiction:
Improveoperator ergonomicsVSAvoidinstallation system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The automated installation system is segmented into distinct functional modules: the decking arm assembly for positioning, the actuator for engagement, the sensor assembly for detection, and the cradle for securing. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while maintaining ergonomic benefits

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The decking arm assembly serves multiple functions: it supports the instrument panel, positions the steering shaft assembly, and works in coordination with the actuator and sensor. This multi-functionality reduces the need for separate dedicated components, thereby reducing device complexity while improving operator ergonomics

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

AI summary

A system and a method of installing an instrument panel in a motor vehicle. The system includes a decking arm assembly having a support structure for supporting the instrument panel, an actuator, a cradle disposed proximate the actuator, and a sensor assembly. The cradle engages a steering shaft assembly of the instrument panel when the actuator is in the advanced position and the sensor assembly does not indicate that the instrument panel is in a desired installation position.
