Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a power storage module and power generation system are included in smart contact lenses, then the lens can sustain operations for longer periods, but the device complexity and size increase
Solution Approach 1:
The smart contact lens system generates its own power through user-driven eye movements that induce current in the induction coil, eliminating the need for external charging and reducing reliance on complex power storage modules. The system serves itself by converting natural user activity into electrical power.
Solution Approach 2:
The patent replaces traditional mechanical power sources (batteries, motors) with an electromagnetic induction system that generates power through eye movement-induced magnetic field changes. This substitution reduces mechanical complexity while maintaining operational duration.
2Power
If the induction coil is moved within a magnetic field to generate power, then electrical power is produced, but user fatigue and strain increase
Solution Approach 1:
The system uses natural, partial eye movements that occur during normal viewing activities rather than requiring excessive or deliberate exercise movements. This approach generates sufficient power without causing user fatigue by utilizing incidental eye motions.
Solution Approach 2:
The power generation system leverages the user's natural eye movements during normal visual tasks to generate power, rather than requiring the user to perform additional exercises. The system converts existing physiological activity into useful power without imposing extra burden.
3Reliability
If power levels are maintained through continuous power generation, then operational reliability is improved, but energy efficiency decreases due to constant motion requirements
Solution Approach 1:
The system accumulates power during periods when eye movements occur (such as during normal visual exploration) and maintains power levels during periods of relative stability. This periodic charging approach improves energy efficiency by generating power only when natural movements occur rather than requiring continuous motion.
