Solution Overview

Problem

Current solutions for addressing dry eye syndrome, dryness of the eye, and stiffness in the neck and shoulder associated with VDT work are inadequate, particularly in terms of efficacy and cost-effectiveness, as the correlation between bilberry extract and these conditions is unclear, and existing methods may not provide sufficient benefits with reduced intake.

Innovation Solution

A composition containing freeze-dried bilberry fruit extract, obtained using water-containing ethanol and processed through filtration, concentration, and purification, followed by freeze-drying to maintain anthocyanin's active properties, is developed to effectively prevent and improve dry eye syndrome, dryness of the eye, and stiffness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional bilberry extract is used for treating dry eye syndrome and stiffness, then the treatment effect is insufficient, but increasing the intake amount increases cost and reduces cost-effectiveness

Engineering Contradiction:
Improvetreatment effectVSAvoidintake amount
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies parameter changes by modifying the physical state of bilberry extract from conventional liquid or powder form to freeze-dried microcapsule form. This transformation increases the surface area and bioavailability of anthocyanins, allowing for more efficient absorption and higher treatment efficacy at lower intake amounts, thus resolving the contradiction between treatment effect and intake quantity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by encapsulating bilberry extract within a freeze-dried matrix structure. This composite formulation protects the active ingredients from degradation while enhancing their stability and bioavailability, enabling effective treatment with reduced dosage and improved cost-effectiveness

Inventive Principle:
Principle #40Composite materials

2Reliability

If conventional drying methods are used for bilberry extract, then the production cost is lower, but the active ingredients are degraded and treatment efficacy is reduced

Engineering Contradiction:
Improveactive ingredient potencyVSAvoidproduction process complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent employs phase transitions by using freeze-drying (lyophilization) which involves freezing the extract and then sublimating the ice directly to vapor. This phase transition process removes water while maintaining low temperatures that preserve anthocyanin integrity, achieving high active ingredient potency despite the more complex production process compared to conventional drying

Inventive Principle:
Principle #36Phase transitions

3Productivity

If VDT work continues without intervention, then productivity is maintained, but dry eye syndrome and neck stiffness worsen

Engineering Contradiction:
Improvework continuityVSAvoidhealth condition
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by providing a preventive composition that can be taken before symptoms of dry eye syndrome and neck stiffness become severe. The freeze-dried bilberry extract preparation allows for proactive health management during VDT work, maintaining both productivity and health condition by preventing deterioration before it occurs

Inventive Principle:
Principle #10Preliminary action
