Solution Overview
Problem
High-precision standard mass weights are difficult to handle efficiently and safely, as ordinary lifting methods can damage the weights and expose them to dust and moisture, affecting their precision and stability during mass measurement.
Innovation Solution
An automatic large-mass-weight handling system comprising a weight picking device, a driving device, and a control unit that allows for precise and automated movement of the weight picking device along horizontal and vertical rails, enabling the system to pick up and transfer large-mass-weights without damaging or contaminating their surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ordinary lifting means are used to handle standard mass weights, then handling operation can be performed, but the surfaces of the weights may be damaged and precision affected
Solution Approach 1:
A specialized handling device with a holding portion is introduced as an intermediary between the operator and the standard mass weights. This holding portion is designed to contact only specific non-critical areas of the weights, preventing direct contact with precision surfaces and thereby avoiding damage while enabling safe handling operations.
Solution Approach 2:
The patent replaces manual lifting operations with an automated handling system that uses a controlled mechanical device. This substitution eliminates the variability and potential damage caused by ordinary manual lifting methods while maintaining precise control over the weights during transfer operations.
2Productivity
If ordinary hoisting manner is used for large-mass-weight measurement, then weights can be picked up and transported, but operation efficiency is low and safety cannot be guaranteed
Solution Approach 1:
The handling device is designed to automatically grasp and release the standard mass weights through a controlled mechanism. The device can autonomously perform the picking up and transporting operations without requiring continuous human intervention, thereby improving operational efficiency and ensuring consistent safe handling practices.
Solution Approach 2:
The specialized holding portion serves as a mediator that ensures safe interaction between the handling system and the precision weights. It is designed to engage with non-critical areas of the weights, preventing damage while enabling reliable and efficient automated handling operations.
3Productivity
If weights are handled repeatedly during mass measuring, then measurement operations can be performed, but weights may be damaged and mass values may change
Solution Approach 1:
The holding portion with specifically designed contact areas acts as a protective intermediary during repeated handling operations. It ensures that only non-critical areas of the weights are contacted, allowing frequent measurement operations to be performed without compromising the precision surfaces or mass values of the standard weights.
4Ease of operation
If manual handling is used for standard mass weights, then weights can be transported to measuring site, but dusts and moisture may adhere to surfaces
Solution Approach 1:
The enclosed handling device with a specifically designed holding portion serves as a protective barrier between the weights and the external environment. This intermediary structure prevents direct exposure of the weight surfaces to dust and moisture during transport operations while maintaining ease of handling.
