Biodegradable Sensor Pad Cover Anti-Slip Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensor pads made of PVC material are prone to displacement and detachment due to their smooth surface, and are affected by temperature and humidity, leading to environmental pollution and user dissatisfaction.
Innovation Solution
A sensor pad cover with a biodegradable PBAT/PLA material outer layer that includes an anti-skid layer to prevent slipping and is unaffected by temperature or humidity fluctuations, reducing environmental impact and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional PVC material is used for sensor pad cover, then the material is durable and easy to manufacture, but the pad becomes slippery and prone to displacement when humidity increases
Solution Approach 1:
The patent changes the material parameters by switching from conventional PVC to a composite material system (PVC base material plus rubber granules). This parameter change modifies the surface friction characteristics of the pad cover, making it less sensitive to humidity variations and preventing the pad from becoming overly slippery in humid conditions.
Solution Approach 2:
The patent applies composite materials by combining PVC base material with rubber granules (5-15% by weight). This composite structure integrates the durability and ease of manufacture of PVC with the high friction and humidity resistance of rubber, resolving the contradiction between manufacturing ease and humidity-related slippage.
2Ease of operation
If conventional PVC material is used for sensor pad cover, then the material provides smooth surface, but the pad is easily displaced and detached when user moves
Solution Approach 1:
The patent uses a composite material consisting of PVC base material combined with rubber granules. The rubber component provides high friction characteristics that prevent the pad from being easily displaced or detached during user movement, while the PVC base maintains ease of placement and operation.
Solution Approach 2:
The patent modifies the friction parameter of the pad cover material by incorporating rubber granules. This parameter change increases the coefficient of friction between the pad and the supporting surface, thereby improving pad attachment reliability without significantly compromising ease of operation.
3Ease of manufacture
If conventional PVC material is used for sensor pad cover, then the material is non-biodegradable, but this causes environmental pollution
Solution Approach 1:
The patent changes the biodegradability parameter of the pad cover material by incorporating biodegradable rubber granules (5-15% by weight) into the PVC base material. This modification enables the composite material to be biodegradable, addressing environmental pollution concerns while maintaining manufacturing feasibility.
Solution Approach 2:
The patent creates a composite material system combining conventional PVC with biodegradable rubber granules. This composite approach allows the pad cover to maintain its manufacturing advantages from PVC while introducing biodegradability through the rubber component, thereby reducing environmental pollution from non-biodegradable waste.
