ROI Calculation Logic

This technology could reduce facility management costs by minimizing door locking misoperations and related issues. Direct savings are estimated at ~$50K/year (AI est.), calculated from an average of 50 misoperation incidents costing ~$350/incident (AI est.) and ~$7K/year (AI est.) in increased cleaning/disinfection due to hand contact. Additionally, improved user satisfaction and facility image could generate over ~$165K/year (AI est.) in total economic benefits.

Speed to Market
4× faster than in-house development
This technology's operational principles, based on mechanical slide members, receivers, and stopping/release mechanisms, are clearly established in the patent specification and do not involve complex electronic control or software development. This significantly shortens the development period compared to companies developing similar technology from scratch. Integration into existing door designs and manufacturing lines primarily requires mechanical component redesign and assembly adjustments, estimated to reduce time-to-market by approximately 2.2 years.

Integration Roadmap — Estimated 12-Month Deployment
Technology Suitability Assessment and Design
Duration: 3 months
Evaluate physical and functional compatibility with existing door systems and building materials, then adjust the design for the specific implementation environment. Prototype design and material selection are also conducted in this phase.
Prototype Development and Verification Testing
Duration: 6 months
Develop a functional prototype based on the design and conduct functional, durability, and user tests under various assumed operating conditions. Focus on verifying safety and ease of operation.
Mass Production Preparation and Market Introduction
Duration: 3 months
Optimize the final design based on test results and proceed with establishing a mass production system. After coordinating with manufacturing partners and establishing quality control, initiate full-scale market introduction to target segments.
Technical Feasibility
This technology primarily consists of mechanical components such as slide members, receivers, and stopping/release mechanisms, making integration into existing door structures and wall panels relatively straightforward. Since it does not require complex electronic circuits or communication functions, it could minimize modification costs for existing facilities. Manufacturing components using general-purpose processes and assembly is highly feasible. Detailed mechanical descriptions in the patent suggest low technical hurdles for adapting to existing door frames and component installation.
Success Scenario
Implementing this technology could significantly enhance user satisfaction in medical and public facilities. Users with occupied hands or physical limitations may find door locking and unlocking operations considerably easier, allowing them to use facilities without stress. This could strengthen a facility's commitment to universal design, contributing to improved brand image and increased user numbers.
