Solution Overview

Problem

Existing compression tools are limited in their ability to securely connect cables to various sized connectors, as they often require multiple tools or complex adjustments to accommodate different connector sizes.

Innovation Solution

A compression tool with an elongated frame, a movable plunger, a handle set, and a rotatable spacer block that can secure connectors at different distances from the anvil, allowing for adjustable compression distances using a toggle action and magnetic retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single compression tool is used for various sized connectors, then versatility is improved, but device complexity increases due to the need for adjustable spacer block positions

Engineering Contradiction:

Improvecompatibility with various sized connectorsVSAvoidcomplexity of adjustable spacer block mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spacer block is made rotatable to allow dynamic adjustment between different connector sizes. The block can rotate between a first position for smaller connectors and a second position for larger connectors, enabling a single tool to adapt to multiple connector types without requiring multiple fixed-tools.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The compression tool is designed with universal applicability by incorporating a spacer block that can be positioned in multiple orientations. This allows the same tool to accommodate various sized connectors (e.g., N-type, SMA, BNC) through a single device rather than requiring separate specialized tools for each connector type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the spacer block is made rotatable for different positions, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improveease of adjusting for different connector sizesVSAvoidcomplexity of rotatable spacer block mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Magnetic elements are incorporated to automatically retain the spacer block in its selected position (first or second position). The magnetic retention mechanism eliminates the need for manual locking or complex fastening systems, allowing the operator to simply rotate the block to the desired position and have it self-secure through magnetic attraction.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The magnetic retention system replaces traditional mechanical locking mechanisms (such as screws, clips, or latches) with a simpler magnetic field-based retention system. This substitution reduces mechanical complexity while maintaining ease of operation, as the magnetic force automatically holds the spacer block in position without requiring additional mechanical components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If magnetic elements are added for retaining the spacer block, then ease of operation is improved, but manufacturing complexity increases

Engineering Contradiction:

Improveease of securing spacer block in positionVSAvoidmanufacturing complexity of adding magnetic elements

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The magnetic elements used for retaining the spacer block are simple, inexpensive components that can be easily manufactured and integrated into the compression tool. These magnetic elements are basic in nature (such as small magnets or magnetic strips) and can be readily sourced or manufactured at low cost, making the addition of magnetic retention a economically feasible solution.

AI summary

A compression tool for fastening a cable to a connector comprising an elongated tool frame, an anvil secured to one end of the tool frame, a compression plunger slidable along a portion of the tool frame, a handle set adapted to move the compression plunger toward and away from the anvil and a spacer block for securing the connector a distance from the anvil. The handle set may include a first handle movable from a first position wherein the plunger is a first distance from the anvil to a second position wherein the plunger is a second distance from the anvil. The spacer block may include a first end and a second end having a different depth from the first end and be rotatable so that the first end when rotated to the active position secures the connector a first distance from the anvil and the second end, when rotated to the active position secures the connector a second distance from the anvil.
