Electronic Control Unit Rack With Movable Cooling Plate Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic control units face challenges in improving the installation of electronic devices, particularly due to the positioning of movable members which can deteriorate the installation process.
Innovation Solution
The electronic control unit includes a rack, an electronic device, a cooling plate, and a movable member. The electronic device is installable along an orthogonal direction, with the cooling plate being movable in the thickness direction of the electronic device. A protrusion on the movable member is received by a guide groove on the electronic device, and an application part constantly applies stress to separate the electronic device and the cooling plate, facilitating easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable member is positioned to hold the cooling plate, then the heat dissipation performance is improved, but the installation process becomes more difficult
Solution Approach 1:
The guide groove is designed with an open end on the leading side in the installation direction, allowing the protrusion to be inserted beforehand. The holding portion is positioned at the trailing end to automatically engage after insertion, enabling preliminary positioning action that facilitates installation while maintaining reliable holding of the cooling plate
Solution Approach 2:
The guide groove acts as an intermediary structure between the protrusion and the holding portion. It guides the protrusion during insertion and transitions it to the holding portion, mediating the interaction between the movable member and the electronic device to enable smooth installation
2Ease of operation
If the guide groove has an open end on the leading side for easy insertion, then the installation ease is improved, but the holding reliability may be compromised
Solution Approach 1:
The guide groove is segmented into two functional zones: the open end portion on the leading side for easy insertion and the holding portion at the trailing end for reliable engagement. This segmentation allows each zone to optimize its specific function without compromising the other

AI summary
In an electronic control unit, an electronic device is installable to a rack along an installation direction orthogonal to a thickness direction. A movable member is disposed in the rack and holds a cooling plate to be movable in the thickness direction. A guide member includes a guide groove and a holding portion at an end of the guide groove. The movable member has a protrusion protruding toward the electronic device to be received in the guide groove. In a mounting state in which the electronic device is mounted to the rack, the protrusion is held by the holding portion and the electronic device is placed in a placement position to face the cooling plate. The electronic control unit includes an application part constantly applying a stress to the movable member in a direction to separate the electronic device and the cooling plate.
