What This Patent Covers

This patent protects a specialized gasket design that prevents formwork over-tightening and eliminates concrete surface waves. Its claims were rigorously established against four prior art documents and two office actions, indicating a robust and stable patent with low invalidation risk, providing a strong foundation for licensees until ~2041.

Competitive White Space

This patent focuses on the gasket's design and function for preventing over-tightening. White space exists in developing smart sensors for real-time formwork tension monitoring or integrating this gasket into fully automated formwork assembly systems.

Economic Impact
~$150K/year estimated repair cost reduction per facility (est.)
estimated ROI · USD · AI analysis
ROI Calculation Logic

Assuming a licensee constructs 100,000 m² of concrete wall surface annually. Conventional repair costs of ~$1.65/m² (AI est.) would result in ~$165K/year (AI est.) in repair costs. This technology eliminates these repairs, projecting equivalent cost savings.

Speed to Market
5× faster than in-house development
This technology has a proven track record with complete validation data, confirming its effectiveness and stability. The physical over-tightening prevention mechanism and center of gravity design algorithms for formwork are already established. Licensees can significantly shorten basic research and prototyping phases, moving quickly to field implementation for rapid market entry and competitive advantage.
