Solution Overview

Problem

Existing nails with RFID transponders are prone to damage during driving, leading to functional failure due to stress and vibrations, which can result in unreliable marking of workpieces, especially when large forces are applied.

Innovation Solution

A nail design featuring a multi-part base body with a receiving space for the RFID transponder, where the front and rear parts are connected at a defined parting surface, providing a stable and secure environment to minimize stress and deformation, and allowing for easy insertion of the transponder before assembly, thus enhancing robustness and reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the RFID transponder is embedded in the plastic material of the nail using injection molding, then the manufacturing process is simplified, but the nail becomes prone to damage during driving due to stress and vibrations

Engineering Contradiction:

Improvemanufacturing processVSAvoidfunctional reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The base body is divided into a first base body part and a second base body part that are connected to each other. The RFID transponder is arranged in a receiving space formed by these two parts, which are connected at a dividing surface. This segmentation protects the RFID transponder from damage during driving while maintaining manufacturing efficiency.

Inventive Principle:

Principle #1Segmentation

2Productivity

If considerable force is applied to drive the nail into the workpiece, then the nail can be driven effectively, but the RFID transponder is at risk of damage and functional failure

Engineering Contradiction:

Improvedriving efficiencyVSAvoidtransponder functionality

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The receiving space is surrounded by a wall with sufficient thickness to absorb and distribute the mechanical stresses and vibrations generated during nail driving. This pre-designed protective structure cushions the RFID transponder against damage while allowing effective driving force to be applied.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Speed

If the nail is driven quickly using a pneumatic or electric nailer, then the marking process is efficient, but the risk of splitting the wood and damaging the transponder increases

Engineering Contradiction:

Improvedriving speedVSAvoidwood splitting and transponder damage

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The base body is divided into two parts connected at a dividing surface, creating a structured assembly that distributes mechanical stresses during high-speed driving. This segmentation prevents wood splitting while protecting the RFID transponder from vibration-induced damage.

Inventive Principle:

Principle #1Segmentation
