Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If computing power of smart contact lenses is increased, then functionality and performance are improved, but heat generation increases causing discomfort and potential overheating
Solution Approach 1:
The patent extracts the cooling function from the contact lens itself by using a wearable cooling device that can be attached to the eye area. This separates the computing function (in the contact lens) from the thermal management function (in the wearable device), allowing the contact lens to maintain high computing power while the external device handles heat dissipation.
Solution Approach 2:
The patent introduces a wearable cooling device as an intermediary between the heat source (contact lens) and the environment. This intermediary device absorbs and dissipates heat from the contact lens, enabling the contact lens to operate at high power levels without directly transferring the thermal burden to the user's eye.
2Temperature
If cooling functions are added to smart contact lenses, then temperature control is improved, but device complexity increases
Solution Approach 1:
The cooling functionality is extracted from the contact lens and placed in a separate wearable device. This division of labor reduces the complexity of the contact lens itself while maintaining effective temperature control, as the contact lens only needs to handle computational functions without integrated cooling mechanisms.
3Temperature
If thermal conductive materials are used in smart contact lenses, then heat dissipation is improved, but manufacturing complexity increases
Solution Approach 1:
The thermal conductive materials and cooling mechanisms are extracted from the contact lens structure and incorporated into a separate wearable device. This extraction simplifies the contact lens manufacturing process while maintaining effective heat dissipation capabilities through the external wearable device that can be more easily manufactured and adjusted.
