ROI Calculation Logic

Assuming 10 users per day in a nursing home require 2 applications/day, 5 minutes/application. Caregiver labor cost at $10/hour (AI est.). Annual assistance time: 10 users × 2 applications/day × 5 minutes/application × 365 days = 608 hours. Total annual labor cost: 608 hours × $10/hour = $6,080 (AI est.). A 30% reduction in assistance could yield annual savings of ~$1,800 per facility (AI est.).

Prototype Development & Evaluation
Duration: 4 months
Manufacture prototypes based on the defined design. Evaluate usability, durability, and container stability from multiple perspectives, identify improvements through user testing, and refine the product.
Mass Production Setup & Market Launch
Duration: 6 months
Establish mass production based on the final design incorporating evaluation results, and set quality control standards. Coordinate with marketing strategy to introduce the product to target markets and establish sales channels.
Technical Feasibility
This technology comprises simple mechanical components: a handle, base, non-slip elements, elastic band, and finger insertion part. The patented structure can be realized with general resin molding, metal processing, and rubber components, making production feasible on existing plastic product manufacturing lines. As it requires no complex electronic control or special materials, new capital investment can be minimized, and rapid commercialization is expected due to high compatibility with a licensee's existing technologies and manufacturing expertise.
Success Scenario
If implemented, this technology could reduce caregiver assistance burden in nursing facilities by approximately 30%, as residents gain the ability to apply ointments independently. This would allow staff to focus on higher-quality care, significantly contributing to resident autonomy and satisfaction. In general households, elderly individuals or those with physical limitations could continue self-care without relying on others, potentially improving their mental quality of life.
