Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If the sensor housing is designed with adequate internal volume to support sensor exposure, then sensor performance is improved, but the housing size exceeds space constraints on micro-mobility vehicles

Engineering Contradiction:
Improvehousing internal volumeVSAvoidadaptability to vehicle space constraints
Core Design Contradiction:
Volume of stationary objectVSAdaptability or versatility

Solution Approach 1:

The sensor housing is designed to be nested within the limited space of a micro-mobility vehicle frame, with the housing itself having a compact tubular shape that fits into available structural voids. The nested design allows the housing to maintain adequate internal volume for sensor exposure while conforming to external space constraints of the vehicle.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Volume of stationary object

If the housing provides ample exposure volume for sensors, then sensing performance is improved, but aerodynamic performance deteriorates

Engineering Contradiction:
Improvehousing internal volumeVSAvoidaerodynamic drag
Core Design Contradiction:
Volume of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The sensor housing employs a streamlined, curved external profile that reduces aerodynamic drag. The housing transitions from a simple rectangular shape to a more organic form with rounded edges and a tapered rear, allowing air to flow smoothly over the housing while maintaining adequate internal volume for sensor exposure.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Ease of operation

If the housing is designed for fixed surface mounting, then installation flexibility is improved, but adaptability to moving vehicle surfaces deteriorates

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidadaptability to vehicle mounting locations
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The housing incorporates a dynamic mounting system with adjustable positioning mechanisms that allow the housing to be securely attached to various locations on the moving vehicle frame. The mounting brackets include adjustment slots and flexible securing methods that accommodate vibrations and movement while maintaining stable sensor positioning.

Inventive Principle:
Principle #15Dynamics

4Reliability

If the housing protects sensors from environmental effects, then sensor reliability is improved, but airflow to sensors deteriorates

Engineering Contradiction:
Improvesensor protectionVSAvoidairflow to sensors
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The housing employs selective protection strategies where different portions of the housing provide different levels of environmental shielding. Critical sensor areas are protected with targeted shields or coatings, while other areas maintain open exposure to ensure adequate airflow. The housing includes localized intake ports and airflow channels that direct air flow precisely to sensor surfaces needing exposure while protecting other components.

Inventive Principle:
Principle #3Local quality

AI summary

A tube mounted sensor housing includes a base with a concave exterior profile and flat interior profile and a sensor chamber formed at the interior profile and defining an interior void. Also included are an air ingress channel disposed between an exterior edge of the base and the interior void of the sensor chamber, and an air egress channel disposed between the interior void of the sensor chamber and the exterior edge of the base. Yet further, an assembly of two separable half covers is removably fixed to the base. One of the half covers includes an air ingress port and an air egress port, such that when the assembly is fixed to the base, the air ingress port aligns with the exterior edge of the base at the air ingress channel, and the air egress port aligns with the exterior edge of the base at the air egress channel.
