ROI Calculation Logic

In large commercial facilities, hospitals, and office buildings, cleaning and disinfecting door handles is essential for infection control, incurring costs of hundreds of thousands of dollars annually. For example, if 1,000 doors require multiple daily disinfection cycles, the combined labor costs for cleaning staff and consumables like disinfectants could reach ~$200K per year (AI est.). By introducing this technology, direct hand contact is significantly reduced. Assuming a 50% reduction in cleaning and disinfection frequency, an annual direct cost saving of approximately ~$100K (AI est.) is achievable. Additionally, improved user satisfaction due to reduced hygiene concerns contributes to intangible asset value.

Speed to Market
6× faster than in-house development
This technology features a clear application as a foot-operated internal lock with a relatively simple mechanical mechanism. Its design replaces existing manual lock knobs with a foot-operated component, avoiding large-scale electronic controls or complex sensor systems. This significantly shortens technical validation and development periods. With the core mechanism already established, focusing on compatibility assessment with existing door structures and implementation design allows for the fastest possible market entry.

Business Models & Applications
📝 Product Licensing
License this technology to existing lock manufacturers and building material suppliers to facilitate the development, manufacturing, and sales of foot-operated internal locking products.
📦 OEM/ODM Supply
Supply components or complete foot-operated internal locks as OEM/ODM to building material manufacturers and general contractors, supporting their product line expansion.
🛠️ Integration into Facility Renovation Projects
Propose and integrate this technology as a solution for facility renovation projects aiming to upgrade aging infrastructure or improve hygiene standards.
Adjacent Application Opportunities
🏭 Cleanroom & Factory
Hygiene Locks for Food Processing
In food processing plants and cleanrooms, this technology allows workers wearing gloves or those needing to avoid hand contamination to operate doors without direct contact. This reduces cross-contamination risks and strengthens HACCP compliance, improving operational safety and product integrity.
👨‍🦽 Barrier-Free Housing
Improved Access for Wheelchair Users
For barrier-free homes and public facility restrooms, this enables wheelchair users to easily lock and unlock doors via foot operation. It resolves challenges with locks positioned out of reach, contributing to greater independence and accessibility for individuals with mobility impairments.
🐶 Pet-Related Facilities
Locks for Pet-Friendly Facilities
In pet hotels or dog cafes, this lock allows users with hands full (e.g., holding a leash) to operate doors stress-free. It enhances customer experience and convenience in pet-friendly environments, streamlining entry and exit for pet owners.
Integration Roadmap — Estimated 18-Month Deployment
Phase 1: Technical Suitability Assessment & Design
Duration: 3 months
Assess the technology's compatibility with existing door systems and fixtures, then optimize the design of the operating body's size and installation standards to meet specific facility requirements.
Phase 2: Prototype Development & Validation
Duration: 6 months
Develop prototypes based on the design, conduct durability, operability, and hygiene effectiveness tests in simulated real-world environments, and apply improvements.
Phase 3: Mass Production & Market Launch
Duration: 9 months
Establish mass production systems based on validation results, followed by pilot operations in initial deployment facilities, leading to full-scale market launch and expansion strategies.
Technical Feasibility
This technology is a mechanical internal lock featuring a foot-operated component that replaces existing manual controls, requiring no complex electronic circuits or communication systems. The mechanism, as described in the patent claims, involves a 'cam member equipped with an operating body, driving the cam member via a rotating shaft,' allowing integration without significant modification to existing door lock mechanisms. Composed of versatile components, it offers high feasibility for relatively easy adoption, minimizing renovation costs for existing facilities.
Success Scenario
Implementing this technology could enable users to lock and unlock shared restrooms in hospitals and commercial facilities without hand contact. This is estimated to significantly reduce contact infection risks and alleviate user hygiene concerns. Furthermore, cleaning staff could be freed from frequent door handle disinfection, potentially saving hundreds of hours of labor annually and contributing to optimized personnel costs.
