Adjustable Rubber Plug Clamping for Multi-Diameter Wire Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rubber plug insertion devices require separate rubber plug holding members for different outer sizes, leading to increased preparation time and costs, and are not adaptable to varying plug types.
Innovation Solution
A rubber plug holding device with multiple clamp members and actuators that adjust to accommodate rubber plugs of varying outer diameters, using pivoting and actuator-driven mechanisms to securely hold plugs of any size, and an electric wire insertion device that integrates this holding device to insert wires into rubber plugs of any diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional rubber plug insertion device uses a fixed rubber plug holding member with a specific outer size, then it can hold rubber plugs of that specific size, but it cannot adapt to rubber plugs of different sizes and requires multiple holding members or frequent replacements
Solution Approach 1:
The clamp members are designed to be movable rather than fixed, allowing them to adjust their positions dynamically. The actuator drives the clamp members to move along the holding member, enabling the device to adapt to different rubber plug outer diameters by changing the clamp members' positions, thus eliminating the need for multiple fixed holding members
Solution Approach 2:
A single holding member is designed to perform multiple functions by accommodating rubber plugs of various sizes. The holding member integrates multiple clamp members that can be adjusted to different positions, allowing one holding member to replace what would traditionally require multiple specialized holding members for different plug sizes
2Adaptability or versatility
If a conventional rubber plug insertion device requires replacement of holding members for different plug types, then it can accommodate different sizes, but it increases preparation time and reduces insertion efficiency
Solution Approach 1:
The clamp members can be dynamically repositioned along the holding member using the actuator, allowing rapid adjustment between different plug sizes without physical replacement of components. This dynamic adjustment mechanism eliminates preparation time associated with changing holding members while maintaining the ability to handle various plug types
Solution Approach 2:
The clamp members are pre-positioned at multiple possible locations along the holding member, ready to be activated into the correct position based on the required plug size. This preliminary arrangement of adjustable components allows immediate adaptation to different plug types without time-consuming replacement operations

AI summary
A rubber plug holding device 30 includes a plurality of first clamp members 31 located around a predetermined central line CL so as to form a space S1 inner thereto in which a cylindrical rubber plug 5 is allowed to be located; a first support member 32 supporting the first clamp members 31; and a first actuator 33 driving the first clamp members 31. The plurality of first clamp members 31 include three or more first rubber plug contact portions 31e1, which are on the space S1 inner thereto and are to be in contact with an outer circumferential surface of the rubber plug 5. The first support member 32 supports the first clamp members 31 such that the first rubber plug contact portions 31e1 get closer to, or farther from, the central line CL. The first actuator 33 drives the first clamp members 31 such that the first rubber plug contact portions 31e1 get closer to, or farther from, the central line CL.
