Solution Overview

Problem

Existing roof modules for autonomous vehicles require complex assembly, multiple fastening components, and a stable roof outer skin to accommodate electronic units, leading to increased complexity and installation space requirements.

Innovation Solution

A roof module with a carrier unit designed as a roof structure component that can be directly fastened to vehicle body framework components, forming a load-bearing receptacle for both the electronic unit and the roof outer skin, simplifying assembly and reducing component count while ensuring stability through a prefabricated design that integrates all necessary units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic unit is fastened to the roof outer skin using a carrier structure, then the electronic unit can be accommodated, but the roof outer skin must be configured to be very stable to accommodate the forces of the electronic unit

Engineering Contradiction:
Improvestability of electronic unit fasteningVSAvoidstrength requirement of roof outer skin
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent introduces a carrier unit as an intermediary component between the electronic unit and the roof structure. This carrier unit absorbs and distributes the mechanical forces, preventing direct transmission to the roof outer skin. The carrier unit includes mounting elements that engage with the roof structure while providing a stable platform for the electronic unit, thus reducing the strength requirements of the roof outer skin itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the electronic unit is fastened via a carrier unit to the body framework component, then the assembly is simplified, but the number of fastening components and assembly steps increases

Engineering Contradiction:
Improvesimplicity of assembly processVSAvoidnumber of fastening components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into the carrier unit: it serves as both the mounting structure for the electronic unit and the fastening mechanism to the roof. The carrier unit integrates mounting elements, fastening components, and structural support functions into a single assembled component, reducing the total number of separate parts while maintaining assembly simplicity.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If multiple separate components are used to fasten the electronic unit to the roof, then the fastening can be stable, but the installation space and assembly outlay increase

Engineering Contradiction:
Improvestability of fasteningVSAvoidinstallation space requirement
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent employs a nested structure where the electronic unit is mounted within or upon the carrier unit, which in turn is integrated with the roof structure. The carrier unit acts as a nested intermediary that consolidates multiple fastening functions into a compact assembly, reducing the overall installation space requirement while maintaining stable fastening through the nested hierarchical structure.

Inventive Principle:
Principle #7Nested doll (Nesting)
