Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a penis extension device is used for permanent lengthening and straightening, then the desired cosmetic effect is achieved, but the device may cause pain and physical damage due to excessive traction force

Engineering Contradiction:
Improvesafety of penis extension deviceVSAvoidpain and physical damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where a traction force measuring device continuously monitors the applied force and an electronic component compares it against pre-stored safe force ranges. When the force exceeds safe limits, an output device provides immediate feedback (visual, acoustic, or haptic) to alert the user to reduce the force, thereby preventing pain and physical damage while maintaining the desired extension effect

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by pre-storing multiple traction force values in a memory device, each associated with a specific class indicating safety status. This allows the system to evaluate the current traction force against predetermined safe thresholds before harmful effects occur, enabling proactive prevention of damage

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the device provides continuous monitoring and feedback of traction force, then safety and user comfort are improved, but the device complexity increases due to additional electronic components

Engineering Contradiction:
Improvesafety monitoringVSAvoidelectronic components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing an electronic component that performs multiple functions: it stores traction force thresholds in memory, reads the current traction force from the measuring device, compares the values to determine safety class, and triggers the appropriate output signal. This multi-functionality reduces the need for separate dedicated components for each function

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

Solution Approach 2:

The patent merges the output device with either the fastening element or the traction device, creating an integrated structure. This combining of components reduces overall device complexity while maintaining the feedback functionality, as the output device becomes part of the existing structure rather than a separate additive component

Inventive Principle:
Principle #5Merging (Combining)
