Vehicle Display Mount With Controlled Bending for Occupant Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display mounting systems fail to adequately address occupant safety and misuse requirements, particularly for displays protruding above the dashboard, while also being suitable for cramped installation conditions and energy absorption during accidents.
Innovation Solution
The mounting system features two half-shell mounts with predetermined bending points, designed to bend in the z and/or y direction under load, connected to a stable crossmember for energy absorption, and includes a flexure mechanism to influence bending behavior, ensuring the display adjusts without breaking during misuse or accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display protrudes beyond the dashboard to improve visibility and user interface accessibility, then the display can be read and operated more easily by driver and passenger, but the risk of injury to occupants increases in the event of an accident
Solution Approach 1:
The mounting system transitions from a static rigid structure to a dynamic system with predetermined breaking points that allow controlled deformation. The mounts are designed to break at specific locations during accidents, enabling the display to fold down safely while maintaining protrusion for normal operation. This dynamic behavior resolves the contradiction by providing both accessibility during use and safety during accidents.
Solution Approach 2:
The mounting system incorporates predetermined breaking points and energy absorption mechanisms designed in advance to protect occupants. The N-shaped mount configuration and specified material properties create built-in safety features that activate during accidents, cushioning the impact before it reaches the occupants. This prior cushioning allows the display to protrude safely.
2Object-affected harmful factors
If the support element is designed to break under excessive load to reduce injury risk, then occupant safety is improved, but the mounting must still withstand misuse forces without damage
Solution Approach 1:
The mounting system applies different structural properties to different parts of the same component. The N-shaped mount has varying wall thicknesses and geometric features that create localized weak points (predetermined breaking points) while maintaining overall structural integrity. The mounts are designed with specific thickness ratios and geometric configurations that ensure breaking occurs at controlled locations rather than failing randomly, thus protecting occupants while resisting misuse.
Solution Approach 2:
The mounting system uses controlled changes in material and geometric parameters to achieve different performance characteristics in different scenarios. By specifying wall thickness ranges, material properties, and geometric dimensions, the design creates a system that breaks at predetermined points during accidents (changing structural configuration) while maintaining sufficient strength to resist normal misuse forces. The parameter changes enable the system to transition between safe failure and durable resistance modes.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively absorbs energy during accidents, reduces the risk of injury by bending the display away from the occupant, and maintains structural integrity against misuse forces without deformation, while being adaptable to different installation spaces.
Implementation Method 1
each of the mounts has at least one predetermined bending point, which is provided by the geometry of the mount, between the two connection points of the mount, the mounts bending at the predetermined bending point in the z and/or y direction in the event of a load (x direction)

AI summary
An assembly for a vehicle comprising a crossmember, which is provided for connecting to two pillars lying opposite each other with respect to the x-y plane of the vehicle; a mounting that is connected to the crossmember, protrudes therefrom in the radial direction, and has two mounts, which are mutually spaced in the y direction, and end-face connection means; and a panel-shaped instrument which is connected to the connection means of the mounting at a distance to the upper closure thereof and which is held such that the operating surface of the instrument faces the passenger compartment of the vehicle in the x direction. Each of the two mounts is designed in the form of a half shell which are arranged such that the opening side thereof faces in the y direction, wherein the two limbs of the mounts designed as half shells are arranged on the x-y plane, the web connecting said limbs is arranged on the y-z plane, and each of the mounts has at least one predetermined bending point, which is provided by the geometry of the mount, between the two connection points of the mount, said mounts bending at the predetermined bending point in the z and/or y direction in the event of a load (x direction).
