Solution Overview

Problem

Existing screen attachment systems for vehicles, particularly those installed at the A-pillar or as replacements for exterior mirrors, often require rigid holders and screws, which can be cumbersome and limit flexibility in installation, especially in confined spaces, and do not effectively secure larger screens.

Innovation Solution

A holding system featuring a pair of identical hooks with U-shaped bolt receptacles that can be arranged on the screen or support element, allowing for multiple fastening options and secure attachment using retaining bolts and screws, enabling easy assembly and robust retention of screens of various sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rigid holders with screws are used to attach screens, then the attachment is secure and stable, but the assembly process becomes cumbersome and complex

Engineering Contradiction:
Improveattachment securityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The holding system is divided into separate functional components: hooks attached to the screen, retaining bolts attached to the support element, and the screen itself. This segmentation allows each component to be prepared independently and assembled through a simple coupling action, reducing overall assembly complexity while maintaining secure attachment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of attaching the screen directly to the support element using screws from the back, the system inverts the approach by using hooks that protrude from the screen front and engage with retaining bolts on the support element. This inversion simplifies the assembly process while maintaining attachment security.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If multiple different fastening components are used to accommodate various screen sizes, then versatility is improved, but manufacturing cost and device complexity increase

Engineering Contradiction:
Improvescreen size compatibilityVSAvoidnumber of different parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hook and retaining bolt design is universal and can accommodate screens of different sizes. The hooks are positioned at adjustable locations on the screen, and the retaining bolts can be positioned at various locations on the support element, allowing the same basic components to serve multiple screen sizes without requiring different fastening mechanisms.

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

Solution Approach 2:

The system incorporates adjustable positioning capabilities where hooks can be relocated on the screen and retaining bolts can be repositioned on the support element. This dynamic adjustability allows a single set of components to adapt to different screen sizes and installation requirements without increasing the number of different part types.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If hooks are made movable on the screen to provide fastening options, then adaptability improves, but assembly precision and reliability decrease

Engineering Contradiction:
Improvefastening option varietyVSAvoidhook position stability
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system separates the positioning function into two independent segments: hook positioning on the screen and retaining bolt positioning on the support element. This allows each to be optimized independently - hooks can be precisely manufactured at fixed locations while still providing adaptability through the selection of different hook positions and bolt positions.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a holding system (3) for fastening a screen (2) to a carrier element (17) of a vehicle, having a hook arrangement that is or can be arranged on the screen (2) and has at least one pair (16) of identical hooks (4), wherein each hook (4) has two side walls (5, 6) which are opposite one another and a base (7) connecting said side walls (5, 6) to one another, which together form an otherwise open bolt receptacle (8) for receiving a holding bolt (18), wherein a screw opening (15) which opens into the bolt receptacle (8) is formed in the base (7), and wherein the hooks (4) of the pair (16) are arranged spaced apart from one another in an unmovable manner on the screen (2) such that the bolt receptacles (8) lie opposite one another and point to one another.
