Innovation Solution
A 3D printed potting mold designed to fit specific dimensions, featuring internal features for component support and a transparent material option for visibility, which can be formed to exact dimensions and contours, reducing material usage and leakage risks, and allowing for easier attachment and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional potting molds are used, then electrical wiring can be protected, but the molds are cumbersome and require removal after curing
Solution Approach 1:
The patent applies preliminary action by preparing the component surface with specific surface energy characteristics before applying the potting mold. The surface is treated to ensure optimal bonding conditions are established in advance, which allows the mold to be removed easily after curing without compromising the bonding reliability of the electrical wiring to the component surface.
2Reliability
If traditional potting molds are used, then electrical wiring can be protected, but the molds are prone to leaking and pooling of uncured potting material
Solution Approach 1:
The patent applies parameter changes by optimizing the surface energy parameters of the component surface. By controlling the surface energy within specific ranges, the patent achieves optimal wetting and bonding of the potting material, preventing leakage and pooling while ensuring reliable encapsulation of the electrical wiring.
3Productivity
If traditional potting molds are used, then electrical wiring can be protected, but further processing of the cured potting material is required
Solution Approach 1:
The patent applies self-service by designing the potting mold with self-release characteristics achieved through optimized surface energy parameters. The mold automatically releases from the cured potting material without requiring manual removal or additional processing steps, thereby improving productivity while maintaining ease of manufacture.

AI summary
A protective enclosure for an electrically-conductive element disposed along a component surface includes a base (16, 116), a first side with an electrical connector, and a second side with an aperture for receiving a potting material (32). The base (16, 116), the first side, and the second side at least partially define an internal void, and the internal void communicates with an external environment via the aperture.
