Electronic Module Holding Element for PCB Surface Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic modules for motor vehicle actuators face challenges in maximizing the use of space on printed circuit boards due to direct attachment methods, which limit the placement of additional components and hinder heat dissipation and vibration resistance.
Innovation Solution
The electronic component is held at a distance from the printed circuit board using a recessed holding element, creating a receiving space that allows for additional components and improved heat dissipation, while also providing stable attachment through pretensionable lugs and thermally conductive adhesive connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If electronic components are glued directly onto the surface of the printed circuit board, then the attachment is sufficiently firm and robust, but a relatively large surface area of the printed circuit board cannot be used
Solution Approach 1:
The holding element elevates the electronic component from the plane of the printed circuit board, utilizing the third dimension (vertical space) to resolve the conflict. By creating a receiving space between the component and board, the solution maintains strong attachment while preserving maximum usable surface area on the board for additional components.
Solution Approach 2:
The holding element acts as an intermediary between the electronic component and the printed circuit board. This mediator provides both mechanical support for firm attachment and creates the necessary spacing to maximize the usable surface area of the board, eliminating the need for direct gluing that would consume board space.
2Strength
If electronic components are attached directly to the printed circuit board, then the attachment is robust, but heat dissipation is hindered
Solution Approach 1:
By transitioning from direct surface attachment to elevated mounting via the holding element, the solution introduces vertical spacing that enables heat dissipation pathways. The receiving space allows heat to dissipate away from the board while the holding element maintains robust mechanical attachment.
3Device complexity
If electronic components are attached directly to the printed circuit board, then the attachment is simple, but vibration resistance is reduced
Solution Approach 1:
The holding element serves as an intermediary that enhances vibration resistance by providing a dedicated mounting structure with pretensionable lugs. This mediator absorbs and distributes vibration stresses, protecting both the electronic component and the printed circuit board while maintaining attachment simplicity through integrated design.
