Solution Overview

Problem

Existing wire body winding devices struggle to securely lock optical fibers with varying thicknesses, leading to potential issues of the fibers coming off or being flipped during the winding process.

Innovation Solution

A wire body winding device featuring a rotating plate with a locking portion that includes a base member and a guide member. The locking portion has a base end portion and a tip end portion, with the distance between the base member and the guide member increasing gradually from the base end toward the tip end, allowing secure locking of wire bodies regardless of their thickness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a fixed locking portion structure is used, then the device complexity is reduced, but the reliability of locking wire bodies with different thicknesses deteriorates

Engineering Contradiction:
Improvelocking portion structureVSAvoidlocking reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The locking portion transitions from a fixed structure to a dynamic adjustable structure. The guide member can be positioned at different locations along the base member, allowing the locking portion to adapt its geometry to accommodate wire bodies of different thicknesses, thereby maintaining reliable locking without increasing overall device complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking portion's geometric parameters are made variable. By changing the position of the guide member relative to the base member, the distance between them can be adjusted to match different wire body thicknesses, ensuring reliable locking across various wire specifications

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the distance between base member and guide member is increased, then wire bodies with larger thickness can be locked, but wire bodies with smaller thickness may not be securely locked

Engineering Contradiction:
Improvewire body thickness rangeVSAvoidlocking security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system employs dynamic adjustability where the guide member position can be changed based on the wire body thickness being processed. This allows the distance between the base member and guide member to be optimized for each specific wire thickness, ensuring secure locking while maintaining versatility across different wire specifications

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking portion is designed with locally optimized characteristics. By positioning the guide member at specific locations along the base member, the local geometry can be tailored to match the specific thickness of the wire body being locked, ensuring optimal contact and locking reliability for each wire type

Inventive Principle:
Principle #3Local quality

AI summary

A wire body winding device includes a rotating plate that rotates together with a drive shaft, a bobbin that is attached to the rotating plate and winds a wire body, and a locking portion that is attached to the rotating plate and locks the wire body. The locking portion includes a base member fixed to the rotating plate and a guide member disposed so as to overlap the base member. The locking portion has a base end portion at which the guide member is fixed to the base member and a tip end portion configured to receive the wire body. The locking portion has a shape in which a distance between the base member and the guide member increases gradually from the base end portion toward the tip end portion.
