Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction components require an outer plastic housing for precise positioning of the coil core and casing, which is not suitable for automatic installation and may not maintain a consistent air gap.
Innovation Solution
An induction component with a housing that includes a holder for the coil core, which secures the core non-displaceably, eliminating the need for an outer housing and ensuring a constant air gap, and features bearing blocks with transverse ribs and conical bearing rests for precise alignment and fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an outer plastic housing with positioning means is used to ensure precise positioning of the coil core and casing, then the air gap can be maintained precisely, but the device complexity increases and it is not suitable for automatic installation
Solution Approach 1:
The invention extracts the positioning function from the outer housing and relocates it to the holder that is integrally formed on the housing base. This separates the positioning function from the enclosing housing structure, simplifying the overall device while maintaining precision.
Solution Approach 2:
The holder is integrally formed with the housing base, merging two components into one. This integration eliminates the need for separate positioning features in the outer housing and simplifies assembly, making it suitable for automatic installation while maintaining air gap precision.
2Manufacturing precision
If an outer housing is used for positioning, then the coil core can be positioned accurately, but the ease of operation for automatic installation deteriorates
Solution Approach 1:
The holder with its bearing blocks and transverse ribs provides self-aligning and self-positioning features. The coil core automatically finds its correct position when inserted, eliminating the need for complex external positioning mechanisms and facilitating automatic installation.
Solution Approach 2:
The holder is pre-formed with bearing blocks and transverse ribs that create the positioning geometry in advance. This preliminary preparation of positioning features simplifies the assembly process, allowing the coil core to be accurately positioned simply by insertion.
3Ease of manufacture
If a holder with bearing blocks and transverse ribs is used to secure the coil core, then the ease of manufacture improves, but the device complexity increases
Solution Approach 1:
The holder is integrally formed with the housing base as a single component. This merging eliminates the need to manufacture and assemble the holder separately, simplifying the manufacturing process while the internal bearing blocks and ribs remain as simple geometric features of the integrated structure.

AI summary
An induction component contains, in a housing, a coil, which has a coil core with two end surfaces and a coil winding. The housing consists of a housing base, in turn consisting of plastic, and a hood-like upper part connected thereto. A holder, in which the coil is held non-displaceably in the direction of its longitudinal axis, is arranged on the housing base. It is thus ensured that the air gaps to the right and left between the end surfaces of the coil core and the inner face of the housing upper part are constant.
