Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard spring blade material is used to exert compression pressure, then urethral compression effectiveness is improved, but comfort deteriorates and trauma risk increases
Solution Approach 1:
The patent changes the material hardness parameter from hard spring steel to soft silicone elastomer with specific Shore A hardness range (20-50). This parameter change allows the material to be soft enough for comfort while maintaining sufficient elastic recovery to compress the urethra effectively, resolving the contradiction between compression effectiveness and comfort.
Solution Approach 2:
The patent uses silicone elastomer as a composite material that combines softness for comfort with high elastic recovery capability for effective compression. The material's viscoelastic properties allow it to deform easily under pinching force while maintaining sustained compression pressure on the urethra, addressing both comfort and reliability requirements.
2Object-affected harmful factors
If soft material with Shore hardness less than 50 is used for branches, then comfort and pressure distribution are improved, but structural strength and durability deteriorate
Solution Approach 1:
The patent specifies Shore A hardness between 20-50 for the silicone elastomer, which is soft enough for comfort but within a range that maintains adequate structural integrity. This parameter optimization allows the soft material to withstand repeated pinching and compression cycles without breaking, resolving the contradiction between comfort and durability.
Solution Approach 2:
The patent designs the compression device as a flexible annular structure made of silicone elastomer that can be pinched between the fingers. The flexible nature of the material allows easy donning and removal while the elastic recovery provides sustained compression. The flexible shell structure resolves the contradiction by being soft enough for comfort yet resilient enough for durability.
3Reliability
If asymmetric design is used for the device, then functional performance is improved, but ease of placement deteriorates due to orientation requirements
Solution Approach 1:
The patent employs asymmetric design in the internal structure and compression mechanism of the device to optimize urethral compression effectiveness, while the external annular shape remains symmetric for easy placement. The asymmetric internal features are concealed within the symmetric outer form, allowing the device to achieve both functional performance and ease of use.
Solution Approach 2:
The patent designs the device with a symmetric annular shape that can be placed in either orientation, making it universal and easy to use. The symmetric external form allows the device to function effectively regardless of orientation, while internal asymmetric features provide the necessary compression mechanism. This multi-functional design resolves the contradiction between functional performance and ease of placement.
4Reliability
If complex attachment mechanisms are used to secure the device, then retention is improved, but ease of use and cleaning deteriorate
Solution Approach 1:
The patent designs the device to be held and retained simply by the user's fingers during use, without requiring separate attachment mechanisms. The elastic recovery force of the pinched silicone structure provides sufficient retention to maintain compression during urination. This self-retaining design eliminates complex attachments, improving ease of use and cleaning while maintaining reliable retention.
Solution Approach 2:
The patent removes complex attachment mechanisms from the device design, relying instead on the elastic properties of the silicone elastomer to provide retention. By extracting unnecessary components, the device becomes simpler to use and clean while maintaining effective retention through the elastic recovery force of the pinched structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides effective urethra compression with higher pressure and improved comfort, while being compact, easy to use, and durable, addressing issues of reliability, hygiene, and manufacturing cost.
Implementation Method 1
at least one of the upper and lower branches, preferably each of the upper and lower branches, called a 'foldable branch', being elastically foldable by pinching the device between the right and left junctions
Implementation Method 2
at least one of the right and left junctions, preferably each right and left junction is elastically deformable under the effect of pinching so as to separate the ends of the upper branch and the lower branch which are physically connected to said junction
Implementation Method 3
The release of this compression produces an elastic return to the rest position, and compression of the penis
