Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adhesive skin patch is made fully adhesive to ensure device adherence, then the device remains securely attached to the skin, but moisture accumulates between the device and skin causing discomfort and potential skin irritation
Solution Approach 1:
The adhesive skin patch is segmented into adhesive regions and non-adhesive regions with cut-outs. The adhesive portions maintain device attachment while the non-adhesive cut-out portions allow moisture to escape from between the device and skin, preventing moisture accumulation and reducing skin irritation risk.
Solution Approach 2:
Different regions of the adhesive skin patch have different properties: adhesive regions provide secure attachment while non-adhesive cut-out regions provide moisture ventilation. This local differentiation allows the patch to simultaneously achieve reliable adherence and moisture management.
2Duration of action of stationary object
If the adhesive skin patch is made fully adhesive to prevent device detachment, then the device remains securely attached during movement and activity, but moisture cannot escape leading to user discomfort and reduced wear time
Solution Approach 1:
The adhesive skin patch incorporates cut-outs that segment the adhesive surface, creating pathways for moisture to escape. This segmentation allows the device to maintain secure attachment through the adhesive regions while enabling moisture ventilation through the non-adhesive cut-out regions, thereby improving user comfort and extending wear time.
Solution Approach 2:
The cut-outs convert the harmful effect of moisture accumulation into a beneficial moisture escape pathway. By intentionally creating non-adhesive regions, the design allows moisture to escape through the adhesive patch itself, transforming the patch from a moisture trap into an active moisture management system.
3Object-affected harmful factors
If the adhesive skin patch includes cut-outs to improve breathability, then moisture can escape to the ambient environment improving user comfort, but the adhesive surface area is reduced potentially affecting device adherence
Solution Approach 1:
The adhesive skin patch is designed with segmented adhesive and non-adhesive regions. The adhesive portions maintain secure device attachment while the non-adhesive cut-out portions provide moisture escape pathways. This segmentation allows the system to achieve both reliable adherence and improved breathability simultaneously.
Solution Approach 2:
Different regions of the patch have differentiated properties: adhesive regions optimized for bonding and non-adhesive cut-out regions optimized for moisture ventilation. This local quality differentiation allows the patch to perform both adhesive and breathability functions effectively without compromising either.
