Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lightweight components, such as aerated concrete and particle board, face issues with inadequate anchoring of connection means due to low density and porosity, leading to potential separation under excessive force, posing a safety risk.
Innovation Solution
A component with distinct exterior and intermediate regions of varying density and modulus of elasticity, where a crosslinked polymer composition is introduced between these regions to create a strong, flexible structure that can securely anchor mechanical connections, eliminating the need for traditional inserts and optimizing force distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional inserts (anchors) are used to connect lightweight components, then the connection means can be applied, but the anchoring is inadequate due to low density and porosity of the material
Solution Approach 1:
The patent changes the physical-chemical parameters of the intermediate region by introducing a polymer composition that undergoes phase transition from liquid to solid through crosslinking. This transformation creates a high-strength anchoring matrix that compensates for the low density of the lightweight component, enabling reliable screw anchoring without increasing the overall material density.
Solution Approach 2:
The patent creates a composite structure by combining the lightweight component (aerated concrete or particle board) with a polymer composition in the intermediate region. This composite approach allows the polymer to provide the necessary mechanical strength for anchoring while the lightweight component maintains its low-density advantages, resolving the contradiction between reliability and material quantity.
2Strength
If inserts are used for connection, then mechanical connection means can be fixed, but the connection can break under excessive force posing safety risk
Solution Approach 1:
The patent applies beforehand cushioning by creating a polymer composition layer in the intermediate region that acts as a stress-absorbing buffer. This polymer layer prevents excessive forces from being directly transmitted to the screw anchoring point, thereby cushioning the connection against overload and preventing catastrophic failure while maintaining strong normal-force connections.
3Adaptability or versatility
If traditional anchoring methods are used, then connection means can be applied, but specific inserts are required for different screw types reducing versatility
Solution Approach 1:
The patent achieves universality by creating a polymer composition-based intermediate region that serves as a universal anchoring matrix for all screw types. Unlike traditional methods requiring different inserts for different screws, this polymer matrix can accommodate any screw configuration, thereby eliminating the need for multiple specialized inserts and significantly improving adaptability while reducing device complexity.
