Solution Overview

Problem

The existing screw-based mounting connection for adjustment instruments in outside mirror units is time-consuming, prone to errors, and can result in vibration and rattling issues due to insufficient or loose screw applications.

Innovation Solution

A mounting construction that eliminates the need for screws by using a clamped connection with projections on both the adjustment instrument and the carrier, ensuring secure attachment and preventing axial displacement, along with an electrical connection for power supply and locking mechanism to prevent uncoupling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a screw connection is used to mount the adjustment instrument to the carrier, then the mounting can be securely achieved, but the assembly process becomes time-consuming and complex

Engineering Contradiction:
Improvemounting securityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The invention extracts and eliminates the screws from the mounting system, replacing the screw-based fastening mechanism with a direct clamped connection between the adjustment instrument and carrier. This removes the time-consuming screw application and tightening steps while maintaining secure mounting through the clamped structural design.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges the mounting function into the structural design of the adjustment instrument and carrier themselves, where the clamped connection is integrated into the components rather than being a separate fastening operation. This combines the structural support and mounting functions into a single integrated system.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If screws are used for mounting, then the adjustment instrument can be attached to the carrier, but assembly errors and mounting failures may occur

Engineering Contradiction:
Improvemounting simplicityVSAvoidmounting reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The clamped connection design is self-aligning and self-securing, where the geometry of the adjustment instrument and carrier automatically ensures proper positioning and secure attachment without requiring operator skill or attention to detail. The clamped structure inherently prevents misalignment and ensures consistent mounting quality.

Inventive Principle:
Principle #25Self-service

3Reliability

If screws are used to secure the adjustment instrument, then mounting can be achieved, but vibration and rattling may occur due to insufficient tightening

Engineering Contradiction:
Improvemounting securityVSAvoidvibration and rattling
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By removing the screws entirely, the invention eliminates the source of vibration and rattling associated with screw heads and threaded connections. The clamped connection provides continuous contact and uniform pressure distribution that prevents vibration without the mechanical imperfections inherent in screw fastening.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Mounting construction for mounting an adjustment instrument to a carrier for an outside mirror unit, comprising first mounting parts on the adjustment instrument and second mounting parts on the carrier, which mounting parts guide the adjustment instrument from a first position to a second position in a direction along the carrier, the mounting parts cooperating with each other in the second position to fix movement of the adjustment instrument relative to the carrier in a direction transverse to the carrier, while in the first position the adjustment instrument and the carrier are clear of each other.
