Element Housing Layout for Upward Heat Discharge in Visual Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing element devices and visual recognition devices face challenges in effectively discharging heat generated by the element body from the coupling portion, leading to potential overheating and operational issues.
Innovation Solution
The element device incorporates a housing body with a metal support body, a coupling portion, and a projection portion that projects beyond the coupling portion, positioning the connector away from the heat discharge path, and a mounting portion that avoids obstructing the convection current, allowing efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector is positioned at the coupling portion to facilitate electrical connection, then electrical connectivity is improved, but heat discharge from the coupling portion is obstructed
Solution Approach 1:
The patent divides the housing body into distinct functional regions: the coupling portion for thermal management and the projection portion for electrical connection. This segmentation allows the connector to be positioned in the projection portion, separating it from the heat discharge path at the coupling portion, thus resolving the conflict between electrical connectivity and heat discharge efficiency
Solution Approach 2:
The patent extends the housing body in the radial direction to form a projection portion that protrudes from the coupling portion. This dimensional extension creates a new spatial zone for placing the connector, allowing electrical connection functionality to be added without interfering with the thermal management function at the coupling portion
2Strength
If the mounting portion is positioned at the coupling portion for structural support, then mechanical strength is improved, but heat discharge path is blocked
Solution Approach 1:
The patent separates the mounting portion from the coupling portion, placing the mounting portion at the end of the projection portion while keeping the coupling portion dedicated to heat discharge. This segmentation ensures that the structural support function and thermal management function operate in separate spatial zones without interfering with each other
Solution Approach 2:
By extending the housing body radially to create the projection portion, the patent provides a new dimensional space for the mounting portion. This allows the mounting function to be positioned away from the coupling portion's heat discharge path while still providing adequate structural support for the element device
3Volume of moving object
If the housing body is compact to reduce size, then device compactness is improved, but heat discharge space is limited
Solution Approach 1:
The patent applies local quality by creating a directional projection portion that extends specifically in the radial direction from the coupling portion. This localized structural modification provides dedicated heat discharge space and connector positioning area without requiring a proportional increase in the overall housing body volume, thus maintaining compactness while ensuring adequate heat management

Implementation Method 1
heat generated by the infrared light source is transmitted to the lid portion via the base plate, the second metal body, and the resin body
Implementation Method 2
a projection portion that is provided at the housing body and that projects further than the coupling portion toward the opposite side from the support body
Data Source
AI summary
In an illumination device, heat generated by a light emitting element is transmitted to a flexible circuit board, a first reinforcement plate, a heat dissipation seal, and a coupling portion of a housing box upper wall, and discharged upward from the coupling portion. A projection portion of a case projects further upward than the coupling portion, and a male connector housed in the projection portion is disposed at a position not opposing an upper surface of the coupling portion. This means that the male connector and the projection portion can be suppressed from impeding a convection current of heat discharged upward from the coupling portion, enabling good discharge of heat generated by the light emitting element upward from the coupling portion.
