Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a fixed girth dilator set is used, then the device structure is simple, but the pressure generation is not gradual and precise control is lost

Engineering Contradiction:
Improvedevice structureVSAvoidpressure control precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent transforms the static fixed-girth dilator into a dynamic adjustable-girth device. The shaft member can be rotated to adjust the girth size, allowing gradual and precise control of pressure against the body orifice. This dynamic adjustment mechanism resolves the contradiction by maintaining structural simplicity while enabling precise pressure control through continuous girth variation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the girth parameter of the shaft member from fixed to variable. By allowing the girth size to be adjusted through rotation of the shaft member, the device can generate gradual and precise pressure control. This parameter change enables the device to adapt to different dilation stages while maintaining a simple overall structure.

Inventive Principle:
Principle #35Parameter changes

2Force

If an inflatable device with fixed pump and pipe is used, then the device can provide pressure, but the design is bulky and compactness is lost

Engineering Contradiction:
Improvepressure generationVSAvoiddevice compactness
Core Design Contradiction:
ForceVSVolume of moving object

Solution Approach 1:

The patent extracts the essential pressure generation function from the bulky inflatable device structure. Instead of using a fixed pump and pipe system, the invention employs a simple rotational mechanism that directly adjusts the girth of the shaft member. This extraction of the core function eliminates unnecessary components, achieving both pressure generation capability and device compactness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the complex pneumatic system (pump and pipe) with a simpler mechanical rotation mechanism. The shaft member's rotation directly controls the girth size, eliminating the need for inflatable chambers and pumping systems. This substitution achieves pressure generation through mechanical means while significantly reducing device volume and improving compactness.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Weight of moving object

If a non-motorized design is used, then the device is lightweight and compact, but the adjustment speed and automation are reduced

Engineering Contradiction:
Improvedevice weightVSAvoidadjustment automation
Core Design Contradiction:
Weight of moving objectVSExtent of automation

Solution Approach 1:

The patent implements a self-service adjustment mechanism where the user directly rotates the shaft member to control girth size. This manual rotation system eliminates the need for motors and electronic controls, keeping the device lightweight and compact. The self-service mechanism maintains full user control over the adjustment process while avoiding the weight and complexity of motorized systems.

Inventive Principle:
Principle #25Self-service

4Productivity

If the shaft girth is adjusted repeatedly, then the dilation and stretch effectiveness is improved, but the risk of over-filling and rupture increases

Engineering Contradiction:
Improvedilation effectivenessVSAvoidover-filling risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent incorporates feedback mechanisms to monitor and control the shaft girth adjustment process. The device provides indicators or sensors that give real-time feedback on the current girth size and pressure levels. This feedback enables the user to adjust the girth gradually and precisely, stopping before reaching the over-filling threshold. The feedback system thus improves dilation effectiveness while preventing the harmful effect of over-filling and rupture.

Inventive Principle:
Principle #23Feedback
