Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If surgical stapling is used to treat hemorrhoids, then the treatment effectiveness is improved, but postoperative pain and complications increase

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidpostoperative pain

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs a disposable proctoscope with integrated positioning features that eliminates the need for expensive, complex surgical stapling devices. The single-use nature ensures sterility and reduces complications while maintaining treatment effectiveness through precise positioning and minimal invasion.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

By modifying the treatment parameters to use less invasive forces and more precise positioning, the device achieves effective treatment while reducing postoperative pain and tissue damage.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If surgical stapling is used to treat hemorrhoids, then the treatment effectiveness is improved, but treatment cost increases

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidtreatment cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces expensive surgical stapling devices with a cost-effective disposable proctoscope. This single-use device achieves the same treatment effectiveness at a fraction of the cost, eliminating the need for expensive reusable equipment while maintaining high reliability through precise positioning and sterile design.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If surgical stapling is used to treat hemorrhoids, then the treatment effectiveness is improved, but surgery time increases

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidsurgery time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The proctoscope incorporates preliminary positioning features including reference markings and an adjustable positioning device that allows the treatment area to be identified and positioned before the actual treatment begins. This preliminary setup enables faster procedure execution while maintaining treatment effectiveness.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention replaces complex mechanical surgical stapling systems with a simpler proctoscope-based approach. By substituting the complicated stapling mechanism with a more straightforward positioning and treatment system, surgery time is reduced while treatment effectiveness is maintained through precise alignment and minimal intervention.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Measurement precision

If precise positioning of treatment area is required, then treatment accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvepositioning accuracyVSAvoidpositioning device complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical positioning systems with a simpler optical/reference marking system. The proctoscope uses visual reference markings and a straightforward adjustment mechanism that achieves precise positioning without the complexity of advanced mechanical systems, maintaining measurement precision while reducing device complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
