Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles equipped with sensor pods face issues due to heat buildup and weather conditions such as ice, snow, and fog, which interfere with the operation of sensors and cameras, leading to reduced visibility and navigation accuracy.
Innovation Solution
A vented sensor pod system with adjustable vents that can open or close to regulate temperature and manage heat buildup, using passive or active actuators to control airflow based on predetermined conditions, thereby maintaining or releasing heat as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the sensor pod housing is sealed to protect sensors from weather conditions, then protection from ice, snow, and fog is improved, but heat buildup from sensors causes overheating
Solution Approach 1:
The patent employs a sealed sensor pod housing that acts as a protective enclosure, similar to a flexible shell, to shield sensors from adverse weather conditions including ice, snow, and fog. This sealed structure maintains environmental protection while the venting system manages thermal conditions.
Solution Approach 2:
The venting system utilizes phase transition principles by allowing controlled opening and closing of vents to transition between sealed (protective) and vented (cooling) states. This enables the system to switch between protection mode and temperature regulation mode based on operational conditions.
2Temperature
If vents are opened to release heat from the sensor pod, then overheating is prevented, but cold air intake may cause freezing in cold weather
Solution Approach 1:
The venting system is designed to be dynamic rather than static, with vents that can automatically open or close based on real-time temperature conditions. This dynamic adjustment allows the system to release heat when overheating occurs while preventing cold air intake when freezing risks exist, optimizing thermal management across varying environmental conditions.
Solution Approach 2:
The system incorporates temperature sensing and control logic that monitors internal sensor pod temperature and automatically adjusts vent positions accordingly. When temperature exceeds thresholds, vents open to release heat; when temperatures approach freezing points, vents close to prevent cold air intake, creating a feedback-based thermal management system.
3Temperature
If a venting system is added to manage heat, then temperature regulation is improved, but device complexity increases
Solution Approach 1:
The venting system is designed to operate autonomously using passive thermal expansion mechanisms and automatic temperature-responsive control. The vents self-regulate based on internal temperature conditions without requiring complex active control systems, reducing overall device complexity while maintaining effective temperature regulation.
Solution Approach 2:
The system utilizes parameter changes in vent positioning (open/closed/intermediate positions) in response to temperature parameter changes. This simple parameter-based control approach enables effective temperature regulation through discrete vent position adjustments rather than complex continuous control mechanisms.
