Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimping tools for cable wires and connectors lack efficiency in crimping multiple wires to a housing simultaneously, requiring multiple steps and potentially causing misalignment or incomplete connections.
Innovation Solution
A crimping hand tool with a linkage mechanism involving multiple bodies and a crimping assembly that allows for simultaneous crimping of multiple wires to a housing, featuring pivotable and sliding components to drive the crimping assembly, along with blades for cutting excess wire and accommodating various housing types through adjustable grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional crimping tools are used to crimp wires to housing, then the connection is secure, but multiple separate steps are required for each wire or housing type
Solution Approach 1:
The patent combines multiple crimping functions into a single integrated tool body. The first and second crimping grooves are positioned on the same housing structure, allowing simultaneous crimping of multiple wires to the same housing or different housing types. The linkage mechanism integrates the motion control of multiple crimping components, enabling coordinated action through a single operator actuation.
Solution Approach 2:
The tool is designed with universal adaptability through multiple crimping grooves that can accommodate different housing types and wire configurations. The first and second crimping grooves can handle various connector types, and the linkage mechanism can adjust to different crimping depths and forces, making the tool versatile for multiple crimping applications.
2Manufacturing precision
If multiple separate crimping operations are performed, then each wire can be crimped individually, but time is lost between operations and alignment errors may occur
Solution Approach 1:
The patent merges multiple crimping operations into a single simultaneous action. The first and second crimping components are linked together through the linkage mechanism, ensuring they move in coordinated fashion. This allows multiple wires to be crimped to the housing at the same time, eliminating the time loss and alignment errors associated with sequential operations.
Solution Approach 2:
The linkage mechanism acts as an intermediary that coordinates the motion between the first and second crimping components. It ensures synchronized movement and proper alignment of the crimping components with the housing, maintaining manufacturing precision while enabling simultaneous operation to reduce cycle time.
3Productivity
If manual wire cutting is performed after crimping, then excess wire can be removed, but additional time and potential misalignment are introduced
Solution Approach 1:
The patent combines the crimping and wire cutting functions into a single integrated operation. The cutting components are positioned to automatically trim excess wire from the housing as the crimping components complete their crimping action. This simultaneous execution of crimping and cutting eliminates the need for separate manual wire cutting steps, improving overall processing speed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables one-time crimping of multiple wires to a housing, ensuring secure connections, reducing the risk of misalignment and increasing efficiency by allowing for various housing types and automatic wire cutting, thus improving the reliability and speed of cable connector formation.
Implementation Method 1
The first end of the first linking body is pivoted to the first body. The third end of the second linking body is slidably coupled to the second body. The fifth end of the third linking body is pivoted to the second body.
Implementation Method 2
The third end of the second linking body is slidably coupled to the second body
Implementation Method 3
the first linking body, the second linking body and the third linking body are driven to push the crimping assembly so as to crimp the wire and housing together
