Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for blepharitis, Meibomian gland dysfunction (MGD), and dry eye syndrome (DES) are inadequate in effectively inducing eye reflexes and preventing permanent skin tissue damage on the eyelids.
Innovation Solution
A dermal conditioning device that generates at least one pressure point on the external surface of the eyelid without tissue coagulation, using a skin tissue lesion generator, controller, power supply, and housing to apply signals and heat, thereby activating eye reflexes and the inflammatory healing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current treatments are used to treat blepharitis and dry eye syndrome, then some symptom relief may be achieved, but they fail to effectively induce eye reflexes and may cause permanent skin tissue damage
Solution Approach 1:
The patent applies controlled mechanical stress parameters (pressure, duration, intensity) to the eyelid skin to induce eye reflexes without causing permanent damage. By precisely controlling these parameters, the treatment achieves reliable reflex induction while avoiding tissue damage that occurs with conventional methods.
Solution Approach 2:
The patent replaces conventional thermal or chemical treatments with a controlled mechanical stress system. The mechanical stress apparatus applies precise physical pressure to the eyelid, substituting harmful thermal/chemical methods with a controllable mechanical system that induces reflexes without permanent damage.
2Productivity
If mechanical stress is applied to the eyelid to induce eye reflexes, then eye reflex induction is improved, but skin tissue damage may occur
Solution Approach 1:
The patent employs periodic or pulsatile application of mechanical stress rather than continuous pressure. This periodic action allows the skin to recover between applications, inducing eye reflexes effectively while preventing permanent tissue damage through controlled intermittent stress application.
Solution Approach 2:
The patent uses a dynamic mechanical stress system that can adjust pressure, duration, and intensity in real-time. This dynamic control allows the system to optimize reflex induction efficiency while adapting to prevent skin tissue damage based on real-time tissue response.
3Duration of action of moving object
If heat is applied to the eyelid to activate inflammatory healing process, then healing is enhanced, but tissue coagulation may occur
Solution Approach 1:
The patent controls heat application parameters (temperature, duration, distribution) to activate the inflammatory healing process without reaching thresholds that cause tissue coagulation. By precisely managing these parameters, the treatment extends healing duration while avoiding harmful thermal effects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively induces eye reflexes such as the corneal, lacrimation, and menace reflexes, which apply pressure to the Meibomian and lacrimal glands, enhancing sebum production and relieving symptoms of MGD and DES without causing permanent damage.
Implementation Method 1
apply the signal to stress the external surface of an outer layer of the eyelid. The stress causes a formation of the pressure point on the eyelid without tissue coagulation
Implementation Method 2
heat can be applied as well to activate the inflammatory healing process of the eyelids

AI summary
A dermal conditioning device is for creating at least one pressure point on at least an external surface of an eyelid. The device includes at least one skin tissue lesion generator, at least one controller, a power supply and a housing, the controller coupled to the skin tissue lesion generator. A power supply couples to the skin tissue lesion generator and the controller and the housing encasing the skin tissue lesion generator and the controller. The controller controls the skin tissue lesion generator to generate at least one signal and to apply the signal to stress the external surface of an outer layer of the eyelid, the stress causing a formation of the pressure point on the eyelid without tissue coagulation, thereby activating at least one of a corneal reflex, a menace reflex, and a lacrimation reflex of the eyelid by activating at least one nociceptor on the eyelid.
