Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If sensors are embedded or attached to the tool holder by destroying the tool holder, then the sensing function is achieved, but the dynamic balance of the tool holder is affected

Engineering Contradiction:
Improvesensing functionVSAvoiddynamic balance
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The tool holder is divided into separate functional components: the main body structure and the sensing unit. The sensing unit is mounted on the surface of the additive body through assembling recesses rather than embedding sensors into the structure, which maintains the integrity and dynamic balance of the tool holder while achieving the sensing function.

Inventive Principle:
Principle #1Segmentation

2Productivity

If long processing time is used, then more processing is completed, but the temperature of the tool holder increases due to poor heat dissipation

Engineering Contradiction:
Improveprocessing timeVSAvoidtool holder temperature
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

A cooling fluid channel system is introduced as an intermediary heat dissipation pathway. The channel includes a coiled structure with inlet and outlet that allows cooling fluid to flow through, absorbing heat from the additive body and sensing unit, thereby maintaining stable operating temperatures during extended processing operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stress or pressure

If the channel inner diameter is reduced to improve pressurization, then fluid flow velocity increases, but the flow rate decreases

Engineering Contradiction:
Improvefluid pressureVSAvoidfluid flow rate
Core Design Contradiction:
Stress or pressureVSQuantity of substance

Solution Approach 1:

The channel incorporates a coiled configuration with varying inner diameters along its length. The coiled structure creates pressure zones that enhance fluid circulation, while the gradual diameter transitions maintain optimal flow rates by reducing turbulence and energy losses.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The channel design features variable inner diameter parameters along its length, with the outlet diameter being smaller than the inlet diameter. This parameter variation creates a pressure gradient that drives fluid flow while maintaining sufficient flow rate through optimized geometric transitions.

Inventive Principle:
Principle #35Parameter changes

4Adaptability or versatility

If multiple sensors are installed on the tool holder, then sensing capability is enhanced, but the installation complexity increases

Engineering Contradiction:
Improvesensing capabilityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The additive body incorporates multiple standardized assembling recesses with uniform structures and symmetric arrangements. These recesses can accommodate different types of sensors (acceleration, torque, temperature) using the same mounting interface, enhancing sensing capability while simplifying installation through standardized components.

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