Wooden RFID Nail Structure for Direct Sensor Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nails for introducing objects or sensors into wood bodies often require pre-drilling, risk damaging tools with metal components, and lack efficient tracking and monitoring capabilities, especially in forestry and logistics where RFID transponders and sensors are needed for identification and environmental monitoring.
Innovation Solution
A nail with a cavity in a predominantly wooden body, designed for direct insertion using a pneumatic tool, accommodating sensors and RFID transponders, and optionally including a shock-absorbing auxiliary substance, allowing for biocompatible and efficient introduction of objects into wood without pre-drilling, enabling continuous monitoring and identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal nails are used to introduce objects into wood, then the nail has high strength and can be driven directly into wood, but the metal nail interferes with signal transmission of RFID transponders and risks damaging woodworking tools
Solution Approach 1:
The nail body is made of composite material consisting of woody plant material combined with reinforcing elements (such as glass fibers, carbon fibers, or other reinforcement materials). This composite structure provides both the necessary mechanical strength for direct insertion into wood and the non-metallic properties required for RFID signal transmission without interference.
2Reliability
If glass fiber reinforced plastic nails are used, then RFID signal transmission is not interfered with, but the production is ecologically unfavorable and woodworking tools suffer increased wear
Solution Approach 1:
The material composition parameters are changed from synthetic glass fiber reinforced plastic to natural woody plant material combined with environmentally friendly reinforcing elements. This parameter change reduces ecological impact while maintaining the non-metallic property needed for RFID signal transmission and reducing tool wear compared to traditional glass fiber reinforced plastics.
Solution Approach 2:
The nail is made predominantly of woody plant material that is homogeneous in composition and similar to the wood into which it is inserted. This homogeneity reduces ecological impact by using biodegradable natural materials and minimizes tool wear by matching the mechanical properties of the target wood, making the nail less abrasive to woodworking tools.
3Reliability
If wooden nails are used, then the nail is biocompatible and does not interfere with RFID signals, but the nail requires pre-drilling of a hole before insertion
Solution Approach 1:
The composite material structure with woody plant material and reinforcing elements provides enhanced mechanical strength compared to pure wood, enabling the nail to be driven directly into wood without pre-drilling. The reinforcing elements increase the nail's ability to withstand insertion forces while maintaining the biocompatible, non-metallic properties needed for RFID compatibility.
