Solution Overview

Problem

Existing Head-Up Display (HUD) systems face challenges in maintaining accessibility to movable parts between the mirror mount and housing, limiting maintenance and adjustment capabilities due to the inaccessibility of the spring after the mirror mount is inserted, which affects vibration resistance and image stability.

Innovation Solution

A method involving a through-hole in the housing allows the spring to be anchored with a stopper that cannot pass through, enabling the spring to be detached and the mirror mount to be removed, while maintaining stability, using a stopper and auxiliary tool for easy installation and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the spring is anchored in the housing after the mirror mount is inserted, then the stability and vibration resistance are improved, but the accessibility to movable parts for maintenance is lost

Engineering Contradiction:
Improvevibration resistanceVSAvoidaccessibility to movable parts
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The housing is segmented into a mounting side and an accessible side, with the spring passing through a through-hole to connect these segments. This allows the spring to be anchored for stability while maintaining accessibility to movable parts on the accessible side for maintenance purposes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring acts as an intermediary element that transmits force between the mirror mount and the housing while allowing controlled movement. By routing the spring through the through-hole, it mediates between the need for rigid anchoring and the need for accessible movable parts.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If the spring is made accessible after mounting, then maintenance capability is improved, but the anchoring stability and vibration resistance are reduced

Engineering Contradiction:
Improvemaintenance capabilityVSAvoidanchoring stability
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The housing is divided into functional zones: a mounting side for secure anchoring and an accessible side for maintenance. The spring traverses through the housing to connect these zones, enabling both stable anchoring and accessible maintenance of movable parts.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring is routed through the housing in a spatial path that allows it to be anchored at one end while extending to the accessible side. This dimensional arrangement enables simultaneous achievement of stability and accessibility without compromising either function.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This approach allows for improved maintenance and accessibility of movable parts, ensuring high vibration resistance and stable image quality by allowing the spring to be disconnected from the mirror mount, while maintaining the same stability as existing systems.

Implementation Method 1

A spring is mounted between the mirror mount and the housing to spring-tension the mirror mount with respect to the housing
