Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing isolating elements for toroidal core inductors face challenges in maintaining stable retention and reliable potential isolation between windings, particularly under temperature changes and manufacturing tolerances, due to their elastic design and limited structural integrity.
Innovation Solution
A two-part isolating element with latching apparatuses and retaining projections that securely fit into a toroidal core inductor's passage opening, ensuring a fixed position and maintaining prestress, thus compensating for dimensional changes and providing a continuous isolating wall without apertures between windings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elastic isolating element with slots is used to achieve spring action, then the isolating element can be retained in the passage opening, but the structural integrity and reliability of isolation are reduced
Solution Approach 1:
The isolating element is divided into multiple isolating web parts (first isolating web part, second isolating web part) that can be assembled together. Each web part contains slots for elastic deformation, but when assembled with latching apparatuses, they form a continuous isolating wall that maintains both elasticity for retention and continuity for reliable isolation.
Solution Approach 2:
Multiple isolating web parts are combined through latching apparatuses to form a unified isolating structure. The latching apparatuses connect the web parts while allowing elastic deformation, merging the benefits of elasticity (for retention) and continuity (for isolation reliability) in a single assembled structure.
2Reliability
If a continuous isolating wall is used to ensure potential isolation, then isolation reliability is improved, but the ability to compensate for dimensional changes due to temperature is reduced
Solution Approach 1:
The continuous isolating wall is segmented into multiple web parts connected by latching apparatuses. This segmentation allows the structure to maintain continuity for isolation while enabling relative movement between segments to accommodate thermal expansion and contraction, thus compensating for dimensional changes.
Solution Approach 2:
The latching apparatuses provide dynamic connection between isolating web parts, allowing the structure to adapt its configuration in response to temperature changes. The connection maintains isolation continuity while permitting elastic deformation and relative movement to compensate for dimensional changes.
3Ease of manufacture
If manufacturing tolerances are present, then production ease is improved, but the retention stability of the isolating element is worsened
Solution Approach 1:
The isolating element is segmented into multiple web parts that are assembled together using latching apparatuses. This modular approach allows each component to be manufactured within standard tolerances while the assembly process ensures proper fitting and retention stability, compensating for individual part variations.
Solution Approach 2:
The latching apparatuses are designed with elastic properties that allow parameter changes (deformation) to accommodate manufacturing tolerances. The elastic material and结构设计 enable the latching mechanism to maintain stable retention despite variations in dimensions of the web parts or passage opening.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides stable retention and reliable potential isolation between windings, maintaining compact dimensions and preventing accidental detachment, while allowing for automated latching verification, ensuring secure and efficient operation.
Implementation Method 1
The isolating element consists of a plate-like material and has two slots which extend into the plate-like material from a first side edge and has a further slot which extends into the plate-like material on the opposite side edge. As a result, the three slots are arranged next to one another in plan view and the isolating element is elastically deformable parallel to its side edges.
Implementation Method 2
The isolating element is then slightly compressed and inserted into the passage opening in the toroidal core inductor. The isolating element then springs open and is then retained in the passage opening in the toroidal core inductor by means of said prestress
