Polyhedral Electronic Component with Recessed Edges for Short-Circuit Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic components, particularly power inductors, face issues with short-circuiting due to exposed electrodes, which can lead to malfunctions when mounted on printed circuit boards, especially with adjacent components or shields.
Innovation Solution
A polyhedral electronic component design with recessed edges and strategically placed insulation layers to limit electrode exposure, preventing short-circuits by ensuring the electrode is only exposed on the mounting surface, thereby reducing the risk of contact with adjacent components or shields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode is exposed on the top surface and side surfaces of the power inductor, then the electrical connection is improved, but short-circuit with shield can or adjacent components may occur
Solution Approach 1:
The patent applies local quality by differentiating the exposure of electrodes on different surfaces of the power inductor. The bottom surface electrode is exposed for electrical connection, while the top surface and side surface electrodes are covered with insulation coating to prevent short-circuits. This localized differentiation of electrode exposure resolves the contradiction between ensuring electrical connection and preventing harmful short-circuits.
2Reliability
If insulation coating is applied to cover exposed electrodes, then short-circuit prevention is improved, but the manufacturing process complexity increases
Solution Approach 1:
The manufacturing process is segmented into distinct steps: forming the electrode pattern, applying the insulation coating, and selectively removing insulation from the bottom surface. This segmentation allows for precise control of where insulation is present and absent, resolving the contradiction between preventing short-circuits and managing manufacturing complexity.
Solution Approach 2:
The insulation coating is applied in advance to all electrode surfaces, and then selectively removed from the bottom surface. This preliminary action of applying insulation first ensures comprehensive coverage to prevent short-circuits, while the subsequent selective removal maintains electrical connection without adding excessive manufacturing complexity.
