Vehicle Fuse Box Groove Layout to Block Liquid Ingress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection boxes allow liquid, such as rainwater, to enter the housing through through holes, leading to potential failure or malfunction of electronic components.
Innovation Solution
An electrical connection box with a removal port and a groove around it that guides liquid away from the port, preventing entry into the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a through hole is formed in the housing to enable electronic component replacement, then ease of operation is improved, but liquid protection is worsened
Solution Approach 1:
The housing is segmented into multiple surfaces with the removal port located on one surface, while groove structures are formed on other surfaces to channel liquid away. This segmentation allows the housing to simultaneously provide access for component replacement and protection against liquid entry through strategic placement of functional features on different surfaces.
Solution Approach 2:
The groove structure acts as an intermediary element between the housing surface and the removal port. It intercepts liquid running down the housing surface and redirects it away from the removal port, preventing direct contact between liquid and the opening without requiring additional active components or complex sealing mechanisms.
2Object-affected harmful factors
If additional liquid prevention devices are added to the housing, then liquid protection is improved, but device complexity is worsened
Solution Approach 1:
The liquid prevention function is merged with the existing housing structure by forming grooves directly on the housing surface. This integration eliminates the need for separate liquid prevention devices while maintaining the housing's primary function of component access, thereby preventing liquid entry without increasing device complexity.
Solution Approach 2:
The housing structure serves itself by incorporating groove features that automatically channel liquid away from the removal port. This self-service approach allows the housing to protect against liquid entry through its own geometric features without requiring additional components or external intervention, simplifying the overall device design.

AI summary
Provided is an electrical connection box with a simple configuration that can prevent liquid from running into a housing. An electrical connection box for a vehicle provided with a case member for installing a first fuse includes a removal port formed at a front surface of the case member, the removal port enabling the first fuse to be installed and removed; and a groove formed around the removal port, the groove guiding liquid running down the front surface away from the removal port.
