Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radar device configurations face challenges in heat dissipation, leading to heat accumulation, increased complexity, and higher manufacturing costs due to the need for waterproofing and periodic fan replacement, which complicates maintenance.
Innovation Solution
The radar device is designed with a housing configuration where the transmitting and receiving units are positioned on opposite sides of the housing, allowing for easier heat dissipation, and the power supply unit is placed on a different wall component to enhance cooling efficiency. Additionally, a sliding frame mechanism facilitates maintenance by allowing components to be extracted outside for easier access and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling fan and ventiduct are provided to improve heat dissipation, then heat dissipation is improved, but device complexity increases and manufacturing cost increases
Solution Approach 1:
The patent extracts the heat-generating components (transmitting unit and receiving unit) from the central housing area and positions them on opposite sides of the housing. This spatial separation allows heat to be naturally dissipated to the outside environment without requiring complex active cooling systems, thereby resolving the contradiction between heat dissipation performance and structural complexity
Solution Approach 2:
The patent designs the housing structure to enable passive heat dissipation through natural convection and radiation. By positioning heat-generating components on opposite sides with access to external environment, the system utilizes natural thermal gradients and airflow patterns to dissipate heat without requiring external cooling devices, thus achieving self-service heat management
2Temperature
If a ventiduct is provided to improve heat dissipation, then heat dissipation is improved, but manufacturing cost increases due to waterproofing requirements
Solution Approach 1:
The patent eliminates the need for ventiducts by extracting heat-generating components to positions where they can directly exchange heat with the external environment through the housing walls. This removes the requirement for complex waterproofed ventilation channels, thereby reducing manufacturing costs while maintaining effective heat dissipation
3Temperature
If a cooling fan is provided to improve heat dissipation, then heat dissipation is improved, but ease of repair deteriorates due to periodic replacement requirements
Solution Approach 1:
The patent implements passive heat dissipation through strategic component placement and housing design, eliminating the need for active cooling fans that require periodic maintenance. The system leverages natural thermal convection and radiation to dissipate heat continuously without mechanical intervention, thereby achieving self-service operation and eliminating maintenance requirements
4Temperature
If transmitting unit and receiving unit are positioned on opposite sides of housing, then heat dissipation is improved, but device complexity increases
Solution Approach 1:
The patent segments the housing into distinct functional zones with transmitting unit and receiving unit positioned on opposite sides. This segmentation creates natural heat dissipation pathways and simplifies thermal management, while the modular layout actually reduces overall system complexity by clearly separating functional components and their thermal zones
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration improves heat dissipation, simplifies the structure, reduces manufacturing costs, and makes maintenance more efficient by allowing for easier replacement of heat-dissipation components and reducing the complexity of the internal layout.
Implementation Method 1
The transmitting unit (6) is attached on the right wall component (3R) side in an internal space of the housing (3), and transmits radar signal through the radar antenna (2)
Implementation Method 2
The receiving unit (7) is attached on the left wall component (3L) side in an internal space of the housing (3), is disposed opposite the transmitting unit (6), and receives reflected wave of the radar signal through the radar antenna (2)
Implementation Method 3
Because the transmitting unit (6) and the receiving unit (7), which generate heat, are thus disposed on either side of a pair of wall components had by the housing (3), any heat generated by the transmitting unit (6) or the receiving unit (7) is more easily released to the outside of the housing (3)
Implementation Method 4
any heat generated by the transmitting unit (6) or the receiving unit (7) is more easily released to the outside of the housing (3)
