Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eyelid care devices with motorized handpieces are unsafe for self-administered use due to the risk of injury, lack of effective stimulation of the meibomian glands, and the potential for micro aerosolization of pathogens. Additionally, existing devices are not designed for easy home use and lack instrumentation for monitoring efficacy and safety.
Innovation Solution
A handheld device with a power supply, motor, detachable head, and oscillating mechanism that provides a safe and effective way to massage and stimulate the eyelids, breaking up accreted meibum in the meibomian glands. The device includes a proximity system and safety features to prevent injury and ensure proper use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If motorized handpieces are used for eyelid care, then productivity and effectiveness of meibomian gland stimulation are improved, but safety and ease of operation deteriorate due to risk of injury
Solution Approach 1:
A gel is introduced as an intermediary substance between the oscillating head and the eyelid. The gel fills in irregularities on the eyelid surface, creating a uniform interface that distributes mechanical forces evenly. This mediator prevents direct contact between the mechanical device and sensitive ocular tissues, thereby maintaining safety while preserving the productivity benefits of motorized stimulation.
Solution Approach 2:
The device incorporates a gel application step before the oscillating head contacts the eyelid. This gel layer acts as a pre-applied cushion that protects the eyelid and cornea from potential mechanical injury. The cushioning is established beforehand, allowing the motorized device to operate at full effectiveness without compromising safety.
2Productivity
If high-speed rotational devices are used for eyelid cleaning, then productivity and cleaning effectiveness are improved, but harmful factors increase due to micro aerosolization of pathogens
Solution Approach 1:
The device uses oscillating mechanical vibration instead of high-speed rotation. The oscillating head moves back and forth at controlled frequencies, effectively cleaning the eyelid and stimulating meibomian glands without generating the centrifugal forces that cause aerosolization. This vibration-based mechanism maintains cleaning productivity while eliminating the harmful aerosol generation associated with rotational devices.
3Reliability
If manual eyelid cleaning methods are used, then safety and ease of operation are improved, but productivity and effectiveness deteriorate due to insufficient stimulation
Solution Approach 1:
The device is designed for self-administered use at home, combining the safety and ease of manual methods with the productivity of motorized devices. Users can safely apply the gel and position the oscillating head themselves, without requiring professional assistance. The motorized oscillation then provides effective meibomian gland stimulation that manual methods cannot achieve, allowing users to benefit from both safety and effectiveness.
Solution Approach 2:
The patent replaces the purely manual mechanical system with a motorized oscillating system. The motor drives the head to oscillate at frequencies and amplitudes that are difficult to achieve manually, providing superior meibomian gland stimulation. This substitution maintains safety through the gel intermediary and controlled operation, while dramatically improving productivity and effectiveness.
4Measurement precision
If motorized devices with complex instrumentation are used, then measurement precision and safety monitoring are improved, but device complexity increases
Solution Approach 1:
The device incorporates sensors that detect parameters such as oscillation frequency, amplitude, and contact pressure. This feedback information is used to monitor the effectiveness of treatment and ensure safe operation. The feedback system provides real-time data without requiring complex instrumentation, allowing precise measurement and safety monitoring while keeping the device relatively simple.
