IP Defensibility — Why Competitors Can't Replicate This
What This Patent Covers

This patent protects a fastening structure featuring a unique combination of a spring washer with a claw and a recessed nut, along with a double-nut mechanism, designed to prevent loosening. The claims were established after overcoming examiner objections, indicating a well-defined scope and high stability against invalidation.

Competitive White Space

This patent focuses on the mechanical design of the fastener components. White space exists in integrating this technology with smart sensing for predictive maintenance or developing novel material compositions for extreme temperature applications.

ROI Calculation Logic

Regular inspection and re-tightening of bolts in bridges and large machinery require specialized personnel. For example, assuming 5,000 inspection points annually, 2 hours per point, 2 workers, and a labor cost of $35/hour (AI est.), the annual cost is $700,000 (AI est.). If this technology could halve the frequency of these tasks, an annual cost reduction of $350,000 (AI est.) is estimated. Further economic loss avoidance from accident prevention is also anticipated.

Technical Feasibility
This technology improves the structure of existing mechanical components like bolts, nuts, and spring washers, thus not requiring large-scale capital investment or complex software development for implementation. The patent claims specifically describe the shapes of the claw and recess features and the double-nut structure. It is estimated that production systems can be established relatively easily by applying existing component processing technologies in current manufacturing lines. Replacement and integration as a general-purpose fastening component are also straightforward, indicating low technical hurdles.
Success Scenario
Upon adopting this technology, the frequency of bolt re-tightening during bridge inspections could be halved annually. This is estimated to reduce inspection costs by approximately 20% and shorten on-site time for workers. Furthermore, improved long-term structural safety is expected to significantly reduce the risk of economic losses from unexpected accidents, contributing to enhanced corporate value.
