Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a compression tool is designed with limited versatility and/or larger size and/or multiple parts and/or multi-step adjustments, then it can handle specific connector types effectively, but operation becomes cumbersome and ease of use deteriorates

Engineering Contradiction:
ImproveversatilityVSAvoidease of use
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The compression tool is designed with a universal body structure that can accommodate multiple connector types through interchangeable components. The body includes a standardized receiving end and die block interface that works with various plunger heads and guideway plates, allowing one tool to perform multiple compression functions without requiring separate tools for each connector type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The tool incorporates moveable guideway plates that can be rotated and adjusted to different positions. These guideway plates are rotatably attached to the body, allowing dynamic reconfiguration of the tool's internal geometry to match different connector sizes and shapes, thereby maintaining ease of operation while handling diverse connector types.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a compression tool is designed with multiple parts and multi-step adjustments to handle different connector types, then versatility improves, but device complexity increases

Engineering Contradiction:
ImproveversatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The compression tool is divided into distinct modular components: a standardized body, interchangeable plunger heads, and rotatable guideway plates. Each component serves a specific function and can be independently selected or replaced. This segmentation allows versatility through component interchangeability while keeping each individual component relatively simple in design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tool merges the functions of multiple specialized compression tools into a single unified device. The body integrates a receiving end, plunger interface, die block mounting, and guideway mechanisms into one structure. By combining these functions that would otherwise require separate tools, the overall device complexity is reduced while maintaining versatility.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If a compression tool uses a standardized body with interchangeable components, then ease of manufacture improves, but ensuring precise alignment and fit during operation becomes more challenging

Engineering Contradiction:
Improveease of manufactureVSAvoidalignment precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The interchangeable components are designed with pre-formed engagement features such as standardized interfaces, keyed connections, and的定位 structures. These features are manufactured in advance with precise tolerances built into the component design, ensuring that when components are assembled, proper alignment is achieved without requiring complex adjustment procedures during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The body acts as an intermediary structure that mediates between the interchangeable components. It provides standardized mounting interfaces and alignment references that guide the plunger heads and guideway plates into correct positions. This intermediary body absorbs the alignment requirements, allowing the interchangeable components to be manufactured separately with standard tolerances while still achieving precise overall alignment when assembled.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

The tool provides versatility, ease of use, and durability by allowing secure compression of different coaxial cable connectors, ensuring reliable connections across various applications.

Implementation Method 1

The plunger is axially advanced to force the coaxial cable connector onto the coaxial cable end, radially contracting the coaxial cable connector into compression engagement with the coaxial cable end

Methodology Applied
