Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing antenna coil core designs, particularly those with a cross-shaped core, face challenges in production efficiency due to difficulties in winding wires and enhancing sensitivity, as they require multiple re-chucking steps and hinder downscaling.
Innovation Solution
A coil part design featuring interlocking first and second winding frame parts, allowing independent winding and separation, which reduces manufacturing steps, enhances sensitivity, and enables efficient storage and transportation by allowing for larger outer radii and smaller central radii, and orthogonal interlocking for improved radio signal reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cross-shaped core is used for three-directional antenna reception, then the antenna can receive radio waves in three axial directions, but the winding machine nozzle cannot approach the winding frame parts due to the other core arms being in the way
Solution Approach 1:
The cross-shaped core is divided into four separate core arms that can be wound independently before assembly. This segmentation allows the winding machine nozzle to access each arm without obstruction from other arms, while the final assembled structure maintains three-directional reception capability through orthogonal arrangement of the arms.
2Adaptability or versatility
If the cross-shaped core is wound as a single integrated structure, then the antenna achieves three-directional reception, but the core must be re-chucked multiple times during winding, reducing production efficiency
Solution Approach 1:
The core structure is segmented into four separate arms that are wound independently as individual components. Each arm can be wound in a single continuous operation without re-chucking, and then the arms are assembled to form the complete cross-shaped core. This segmentation eliminates multiple re-chucking operations and improves production efficiency while maintaining the three-directional reception capability.
Solution Approach 2:
The core arms are prepared in advance as separate wound components before final assembly. By pre-winding each arm independently to completion, the preliminary action is performed on manageable segments rather than attempting to wind the entire cross-shaped core in one operation, thereby eliminating repeated re-chucking steps.
3Productivity
If the core structure is designed for easy winding access, then production efficiency improves, but the antenna sensitivity enhancement and downscaling demands cannot be satisfied
Solution Approach 1:
The core is segmented into four independently wound arms that can be optimized for both manufacturing efficiency and antenna performance. Each arm's geometry and winding parameters can be independently adjusted to enhance sensitivity while maintaining easy access for winding operations, thus satisfying both productivity and reliability requirements.
Solution Approach 2:
Different regions of the core structure are given different properties: the core arms are designed with specific geometries and winding densities optimized for local magnetic field generation, while the overall assembly configuration optimizes three-directional reception. This local quality optimization allows sensitivity enhancement without compromising production efficiency.
