Coil Unit Guide Part for Orderly Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coil units face issues with orderly winding of coils due to overlapping crossover wires, leading to improper alignment and winding of coils, which affects the functionality of photographing optical devices.
Innovation Solution
The coil unit features a coil holding member with recessed coil guide parts on its outer peripheral face, ensuring that crossover wires are guided correctly, preventing them from overlapping with the coils and allowing for orderly winding, even when the coils and crossover wires are disposed in a protruding direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If crossover wires are used to serially connect coils on adjacent side faces, then electrical connectivity is achieved, but the wires may overlap with coils and disrupt orderly winding
Solution Approach 1:
The patent introduces a holder as an intermediary component that provides dedicated wire routing paths (grooves and surfaces) for crossover wires. This mediator structure guides the wires between coils without allowing them to overlap with the coils themselves, thus maintaining both electrical connectivity and orderly winding arrangement.
Solution Approach 2:
The holder is segmented into multiple functional regions: coil mounting areas, wire routing grooves, and abutting surfaces. This segmentation separates the functions of coil support and wire routing into distinct spatial zones, preventing interference between coils and crossover wires while ensuring proper electrical connections.
2Ease of manufacture
If coils are directly wound around protruded parts on side faces, then assembly is simplified, but crossover wire routing becomes problematic causing disordered coil winding
Solution Approach 1:
The patent merges the functions of coil support and wire routing into a single integrated holder structure. The holder simultaneously provides protruded parts for coil winding and incorporates grooves and surfaces for wire routing, eliminating the need for separate wire management components and maintaining assembly simplicity.
Solution Approach 2:
The holder serves multiple functions: it supports coils on its side faces, provides abutting surfaces for coil positioning, and incorporates routing paths for crossover wires. This multi-functional design achieves both simplified assembly and proper wire management without increasing device complexity.

Function Achieved in This Case
This solution ensures that coils can be wound orderly around the protruded parts, enhancing the structural integrity and operational efficiency of the coil unit and the photographing optical device, while also simplifying the assembly process and reducing the number of components.
Implementation Method 1
a coil holding member which holds the even number of the coils
Implementation Method 2
The side face is formed with a protruded part around which one of the coils is directly wound
Implementation Method 3
The side face is formed with an abutting face with which one end face of the coil wound around the protruded part is abutted

AI summary
A coil unit may include coils and a coil holding member. An outer peripheral face of the coil holding member includes two side-face pairs, each of which includes a pair of parallel side faces. Each side face includes a protruded part around which the coil is wound and an abutting face with which one end face of the coil is abutted. Two pieces of the coil wound around protruded parts of two paired side faces is formed of one conducting wire. One side faces includes a coil guide part for wiring a crossover wire which connects the coil wound around the protruded part of one side face with the coil wound around the protruded part of the paired side-face pair, the coil guide part being recessed from the abutting face, and a recessed amount of the coil guide part is not less than an outer diameter of the conducting wire.
