Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mass-produced vehicles lack the necessary sensors for autonomous operation, hindering their ability to function in autonomous or semi-autonomous modes without driver input.
Innovation Solution
A sensor module assembly with a lock, computer, and releasable coupling is integrated into the vehicle's roof, allowing for secure attachment and detachment, enabling the vehicle to operate autonomously by controlling propulsion, braking, and steering through a network of sensors and electrical communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If sensors are integrated into mass-produced vehicles for autonomous operation, then autonomous driving capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent divides the autonomous vehicle sensor system into a separate, modular sensor module that can be independently installed and removed. This segmentation allows mass-produced vehicles to gain autonomous capability without permanently modifying their core structure, thereby reducing overall system complexity while enabling automation.
Solution Approach 2:
The sensor module is designed as a universal component that can be attached to various vehicle types through a standardized interface. This multi-functionality allows the same sensor assembly to equip different mass-produced vehicles, simplifying manufacturing by using common parts across multiple vehicle models while enabling autonomous operation.
2Extent of automation
If sensors are permanently installed in mass-produced vehicles, then autonomous operation is enabled, but ease of manufacture and customization are reduced
Solution Approach 1:
The sensor module employs a dynamic attachment system with releasable couplings that allow the sensors to be easily installed or removed based on operational needs. This dynamic design enables manufacturers to produce vehicles without sensors and add them later, or remove them for customization, thereby maintaining manufacturing flexibility while enabling autonomous operation when required.
Solution Approach 2:
By separating the sensor system into an independent module rather than integrating it permanently into the vehicle structure, the patent allows manufacturers to produce base vehicles using standard processes and then selectively add autonomous capabilities through module installation, preserving ease of manufacture and production flexibility.
3Reliability
If a secure locking mechanism is used for the sensor module, then reliability of sensor attachment is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical locking systems with simpler magnetic couplings that provide secure attachment through magnetic attraction. This substitution maintains reliable sensor module attachment while significantly reducing the complexity of the locking mechanism, as magnetic forces require fewer moving parts and simpler actuation systems.
Solution Approach 2:
The releasable coupling acts as an intermediary between the sensor module and the vehicle body, providing a balanced solution that achieves reliable attachment without requiring complex locking mechanisms. The coupling mediates the connection through a combination of magnetic attraction and mechanical features that are simpler than traditional locking systems.
