HUD Mounting on Steering Column Bracket

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The instrument panel lacks spare space for a large-sized head up display unit due to the presence of a load-absorbing structure that collapses in the vehicle front direction, making it difficult to directly mount a large head up display unit inside the panel.

Innovation Solution

A mounting structure that includes a vehicle body strength member at the rear side of the front wall panel, a column bracket at the lower portion of the vehicle body strength member to mount the steering column, and a head up display unit that is movable upward in response to an emergency input load from the vehicle front direction, allowing efficient space-saving mounting and separation from the vehicle body strength member or steering column.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If a large-sized head up display unit is directly mounted in the inner portion of the instrument panel, then the display area and information quantity are increased, but the head up display unit cannot be mounted due to the presence of the load absorbing structure

Engineering Contradiction:

Improvedisplay areaVSAvoidmounting feasibility

Core Design Contradiction:

Area of moving objectVSEase of operation

Solution Approach 1:

The head up display unit is mounted on the column bracket positioned above the instrument panel rather than directly in the inner portion, utilizing the vertical dimension to bypass the space occupied by the load absorbing structure while maintaining display functionality

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The column bracket serves as an intermediary mounting structure between the vehicle body and the head up display unit, enabling the display to be positioned in a location that avoids conflict with the load absorbing structure while still providing adequate display area

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the head up display unit is fixed rigidly to the vehicle body strength member, then mounting stability is improved, but the head up display unit cannot separate during emergency loads causing potential damage

Engineering Contradiction:

Improvemounting stabilityVSAvoiddamage from emergency load

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The mounting structure transitions from a static rigid connection to a dynamic system where the head up display unit can move upward relative to the column bracket during emergency loads, allowing the system to adapt to varying load conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mounting structure is designed with predetermined upward movement capability that allows the head up display unit to separate from the column bracket before excessive forces can cause damage, effectively cushioning against emergency load impacts

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A head up display unit can be provided in an inner portion of an instrument panel. A column bracket for mounting a steering column is at a lower portion of a vehicle body strength member and extends in a vehicle width direction in a vehicle rear side of a front wall panel of a vehicle interior. The head up display unit is mounted on the column bracket so as to be movable to a vehicle upward direction by an emergency input load from a vehicle front direction.
