RFID Tool Lanyard Assembly for Heavy-Load Attachment Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lanyards are unreliable for securing larger or heavier tools due to frequent breakage, and lack features for easy tool attachment and tracking.
Innovation Solution
A heavy-duty lanyard system with a strap, cinch, and carabiner that includes a swivel member for 360-degree rotation, quick connect attachment mechanisms, and RFID tracking for tool management, along with color coding for weight ratings and durable materials like metallic carabiners and elastic components for shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lanyards are used to secure tools, then tools can be attached to the lanyard, but the lanyards frequently break making them unreliable for larger or heavier tools
Solution Approach 1:
The lanyard system is divided into multiple components: a separate strap, a carabiner with locking bar, and a cinch mechanism. This segmentation allows each component to be optimized for its specific function - the strap for flexibility, the carabiner for secure attachment, and the cinch for tool retention - thereby improving overall reliability without compromising strength.
2Reliability
If carabiners with locking bars are used to securely clip tools, then secure attachment is achieved, but the attachment mechanism becomes more complex
Solution Approach 1:
The carabiner locking bar is designed to automatically engage with the frame aperture and lock into place through its own weight and spring mechanism, without requiring manual intervention or complex locking procedures. The tool cinch also self-adjusts to secure the tool, reducing the need for complex manual attachment mechanisms while maintaining high security.
3Strength
If lanyards are designed for heavy duty use with durable materials, then strength is improved, but the weight of the lanyard increases
Solution Approach 1:
Different parts of the lanyard system use materials with appropriately matched properties for their specific functions. The strap uses high-strength synthetic material that is lightweight, the carabiner uses aluminum alloy for strength-to-weight ratio, and the cinch uses elastic material for shock absorption. This localized material selection optimizes strength while minimizing overall weight.
