Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If removable prostheses are used with traditional anchors, then the patient can remove the prosthesis for cleaning, but the patient experiences a sensation of mobility and discomfort
Solution Approach 1:
The patent applies the dynamics principle by designing a retention element with elastic properties that can dynamically adapt to occlusal loads. The element deforms elastically under chewing forces and returns to its original position, providing both stability during function and controlled mobility for removal. This dynamic behavior resolves the contradiction between feeling stable during use and being removable for cleaning.
Solution Approach 2:
The patent changes the physical parameters of the retention element by using elastic materials and designing specific geometries (such as hollow cylindrical shapes with controlled wall thicknesses) that provide optimal elastic deformation characteristics. This parameter optimization allows the element to maintain stability under load while enabling easy removal, addressing the contradiction between prosthesis stability and removability.
2Adaptability or versatility
If traditional anchors with minimal thickness are used to favor elastic property, then the retaining element can change geometry, but the anchor contributes little stability and offers lack of retention
Solution Approach 1:
The patent applies the nesting principle by designing a retention element with a hollow cylindrical geometry that fits within the anchor structure. This nested configuration allows the retention element to deform elastically within the confined space while maintaining overall structural integrity and retention capability, resolving the contradiction between elastic adaptability and reliable retention.
Solution Approach 2:
The patent uses composite material principles by combining elastic materials with specific geometric designs (hollow cylindrical structures with optimized wall thicknesses) to create a retention element that provides both elastic deformation capability and sufficient mechanical strength for stable retention, addressing the contradiction between adaptability and reliability.
3Duration of action of stationary object
If anchors rely on mechanical elastic capacity with minimal thickness, then the retaining element can return to original geometry, but there is a lack of resilience and increased wear
Solution Approach 1:
The patent applies the local quality principle by designing the retention element with non-uniform wall thickness distribution and specific geometric features (such as varying thickness in different sections) that concentrate elastic deformation in specific areas while maintaining strength in other regions. This localized optimization provides both recovery capability and wear resistance, resolving the contradiction between duration of action and strength.

AI summary
A dental anchoring system for fastening prostheses having a male component, a female component which is coupled to the male component, and a connection element which is coupled to the female component and makes up the retaining element of the prosthesis configured to be joined to the connection element. The dental anchoring system is configured to achieve a self-adjustable fastening of the prosthesis which enables the mobility of prosthesis to be controlled when it is subjected to a load during the use thereof by a patient; and wherein the mobility is limited by a ring-shaped stop of the female component, when at least one portion of a ring-shaped plane of the connection element comes into contact with ring-shaped stop of the female component.
