Solution Overview
Problem
Manual recording of work operations in outdoor environments lacks objective traceability and independent certification, as workers compile their own records without quality or result information, leading to unreliable documentation.
Innovation Solution
A portable work equipment system that includes a tool with a control system and wireless communication to transmit work cycle parameters to a portable electronic device, which generates traceability data-sets with GPS coordinates, date, and time, and sends them to a central database, ensuring objective and reliable record-keeping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual recording of work operations is used by workers, then the documentation process is simple and requires minimal equipment, but the traceability lacks objectivity and independent certification
Solution Approach 1:
The patent introduces an intermediary automated system consisting of a control unit on the tool and a portable electronic device that mediates between the work operation and the central database. This intermediary automatically captures work cycle parameters via sensors and transmits them with GPS coordinates and timestamps, eliminating the need for manual recording while ensuring objective traceability and independent certification of work operations.
2Reliability
If automated traceability system with real-time transmission is implemented, then objective and reliable traceability is achieved, but the device complexity and cost increase
Solution Approach 1:
The tool's control unit automatically performs self-service by detecting work cycle parameters through integrated sensors, generating traceability data-sets with embedded timestamps and GPS coordinates, and transmitting this data without requiring external intervention. This self-service capability reduces the need for complex external monitoring systems while maintaining high documentation reliability.
Solution Approach 2:
The portable electronic device serves multiple functions: it receives data from the tool, generates traceability data-sets, transmits data to the central database, and provides independent certification. This multi-functional approach consolidates several system components into a single device, reducing overall system complexity while achieving reliable automated traceability.
3Loss of information
If continuous monitoring and real-time data transmission are performed, then complete traceability of work operations is achieved, but energy consumption and time loss increase
Solution Approach 1:
The system maintains continuous monitoring and real-time data transmission throughout the work process without interrupting the useful action of manipulating work pieces. The control unit continuously detects work cycle parameters and transmits them in real-time, ensuring complete information capture while allowing the work process to proceed uninterrupted, thus minimizing time loss.
