Screwdriver Shaft Electronic Tag Reader for Accessory Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screwing systems face challenges in efficiently recognizing and adapting to different screwing accessories, such as sockets and shaft transmissions, due to impractical designs and exposure to environmental shocks, leading to inefficiencies and errors in precision tightening operations.
Innovation Solution
A screwing system with an electronic tag reader and tag positioned in the axis of the output shaft, allowing secure attachment of various accessories like sockets and shaft transmissions, while protecting the reader and tag from environmental impacts, enabling robust and ergonomic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic tags and readers are placed on the periphery or surface of the accessory or screwdriver for recognition, then accessory identification is enabled, but the reader and tag are exposed to shocks with the external environment during manipulation
Solution Approach 1:
The electronic tag reader is integrated into the hollow interior housing of the output shaft, creating a nested structure where the reader is positioned inside the shaft rather than on the external surface. The electronic tag on the accessory is positioned to be readable by this internal reader when the accessory is secured to the screwdriver, protecting both components from external shocks while maintaining recognition functionality.
2Measurement precision
If socket boxes with presence sensors are used to automatically select screwing strategies, then strategy selection accuracy is improved, but the device volume increases and cables are required which are impractical in cramped workspaces
Solution Approach 1:
The invention extracts the electronic tag reader from a separate socket box unit and integrates it directly into the screwdriver's output shaft. This eliminates the need for a separate box and connecting cable, reducing overall device volume and improving ergonomics in cramped workspaces while maintaining the automatic strategy selection capability through the electronic tag recognition system.
Solution Approach 2:
The reader function is merged with the screwdriver body by positioning the reader inside the hollow interior housing of the output shaft. This integration combines the recognition system with the driving mechanism, eliminating separate components and cables while enabling automatic accessory identification and strategy selection.
3Adaptability or versatility
If means for attaching screwing accessories are designed to secure different sockets or screwing patterns, then versatility of attachment is improved, but the ability to fasten different types of accessories like shaft transmissions is limited
Solution Approach 1:
The output shaft is designed with a hollow interior housing that can accommodate different types of screwing accessories including sockets and shaft transmissions. The electronic tag reader positioned inside this housing can read tags on various accessory types, enabling a single attachment mechanism to handle multiple accessory types without requiring separate specialized mechanisms for each type.
