RF Tag Attachment With Silicone Wrap for Waterproof Hand Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching RF tags to tools, such as using pressure-sensitive adhesive tape, banding bands, liquid rubber, or heat-shrinkable tubes, face issues like poor waterproofness, weather resistance, and positional shifting or loosening due to environmental factors, making it difficult to maintain RF tag attachment over time, especially in harsh outdoor conditions.
Innovation Solution
The use of a self-adhesive silicone rubber bonding member, which includes a first bonding member wound around the tool over the RF tag and a second bonding member disposed between the tool and the RF tag, provides a durable and waterproof attachment solution, ensuring the RF tag remains fixed at accurate positions for extended periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pressure-sensitive adhesive tape or double-sided pressure-sensitive adhesive tape is used to attach RF tags to tools, then the attachment process is simple and convenient, but the waterproofness and weather resistance are poor, causing the RF tag to become loose over time when used outdoors
Solution Approach 1:
The patent uses a composite bonding structure combining self-adhesive silicone rubber sheet (providing waterproofness and weather resistance) with pressure-sensitive adhesive tape (providing ease of attachment). The silicone rubber sheet is wrapped around the tool and RF tag to form a protective bonding member that maintains both convenience and reliability.
2Reliability
If banding band (cable tie) is used to attach RF tags to tools, then the attachment is secure, but the banding band becomes loose in harsh environments due to expansion and contraction or degradation of resin
Solution Approach 1:
The patent changes the material parameter from conventional banding band resin to self-adhesive silicone rubber, which has superior resistance to expansion, contraction, and degradation in harsh environments. The silicone rubber bonding member maintains its bonding properties over time, ensuring long-term stability while providing secure attachment.
3Reliability
If liquid rubber is used to attach RF tags to tools, then the attachment can be made, but the position of attachment is easily shifted because the liquid rubber is liquid at the time of attaching
Solution Approach 1:
The patent applies pressure-sensitive adhesive tape locally at the attachment position to provide immediate positioning accuracy, while the self-adhesive silicone rubber sheet is wrapped around to provide overall bonding strength. This combination ensures both precise positioning and strong bonding without the shifting problem of liquid rubber.
4Reliability
If heat-shrinkable tube is used to attach RF tags to tools, then the attachment is durable, but it is difficult to attach RF tags to positions unable to be fitted into the tube (e.g., ring-shaped portion or portion too thick)
Solution Approach 1:
The patent creates a universal attachment solution where the self-adhesive silicone rubber sheet can be wrapped around various tool shapes and positions, including ring-shaped portions and thick portions that cannot accommodate heat-shrinkable tubes. The flexible sheet adapts to different geometries while providing durable attachment, making the system versatile for all tool types.
