Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple spring is used to keep vise parallels apart, then the device is simple and easy to use, but the machinist wastes a large amount of time searching for the correct spring among random springs in a collection bin

Engineering Contradiction:

Improvesimplicity of retaining deviceVSAvoidtime to find correct spring

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The device segments the spring selection problem by providing dedicated storage compartments for different spring types and sizes within the vise body itself, eliminating the need to search through a random collection bin. Each compartment is designed to hold specific spring configurations, allowing rapid selection without time-consuming searches.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The vise body acts as an intermediary between the spring storage and the working spring, providing organized compartments that mediate the selection process. This intermediary structure transforms the chaotic search through a collection bin into an organized selection from designated storage areas within the vise itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a complex holder device with multiple retaining members and guide arrangements is used, then the parallels are securely retained, but the device becomes complicated and is replaced often

Engineering Contradiction:

Improvesecurity of parallel retentionVSAvoidcomplexity of holder device

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential function of spring retention from complex holder devices with multiple retaining members and guide arrangements. By using only the spring element itself in a simple compressed position between the parallels, it achieves the necessary retention security without the unnecessary complexity of additional retaining plates, tubes, or guide arrangements.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using complex holder devices that hold springs, the invention inverts the approach by having the springs directly engage and retain the parallels through their own elastic properties. The vise jaws provide the holding structure, while the springs provide the retaining force, eliminating the need for separate holder devices.

Inventive Principle:

Principle #13The other way round (Inversion)

3Adaptability or versatility

If an adjustable threaded connection is used between compressible and incompressible members, then the device provides robust and adjustable retaining forces, but the manufacturing complexity increases

Engineering Contradiction:

Improveadjustability of retaining forceVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The adjustable threaded connection introduces dynamics to the device by allowing the retaining force to be adjusted according to different workpiece requirements. The threaded mechanism enables variable compression of the spring, providing adaptable retaining forces while maintaining a relatively simple overall structure that does not significantly increase manufacturing complexity.

Inventive Principle:

Principle #15Dynamics
