Weigh Module Horizontal Constraint and Anti-Overturn Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weigh modules in industries such as cement, metallurgy, and chemical processing are prone to damage and reduced reliability due to lack of horizontal protection and anti-overturn structures, causing instability when subjected to forces like wind or intrinsic forces, which can lead to the weighed object moving and the module being compromised.
Innovation Solution
A weigh module design featuring a supporting member with a receiving hole and a connecting member that includes a limiting end to prevent displacement, combined with a sealing member having a swelled raised portion generating a restoring force to maintain stability and prevent the object from falling, utilizing a load cell, guiding member, and sealing components for enhanced protection and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a weigh module is installed under the weighed object without horizontal protection and anti-overturn structures, then the weighing function is simple and the device complexity is low, but the weigh module is easily damaged and the working reliability is lowered when subjected to external forces
Solution Approach 1:
The supporting member is divided into multiple functional segments: the receiving hole for vertical support, the limiting end for horizontal constraint, and the sealing member with swelled raised portion for anti-overturn protection. Each segment performs a specific function, allowing the system to achieve high reliability through modular structural division without excessive complexity.
Solution Approach 2:
The patent transitions from simple vertical weighing to multi-dimensional constraint by adding horizontal protection structures. The limiting end extends horizontally to prevent lateral movement, while the swelled raised portion provides anti-overturn capability in the rotational dimension, thereby protecting the weigh module from damage without significantly increasing overall complexity.
2Stability of the object's composition
If the supporting member is made stable against horizontal forces, then the reliability is improved, but the device complexity increases due to additional protection structures
Solution Approach 1:
The patent merges multiple protective functions into integrated structures. The sealing member combines sealing functionality with anti-overturn protection through its swelled raised portion. The connecting member integrates load transmission with horizontal limiting capability. This merging approach achieves high stability while minimizing the number of separate components, thereby controlling structural complexity.
3Measurement precision
If the connecting member includes a limiting end to prevent displacement, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The limiting end acts as an intermediary element between the supporting member and external horizontal forces. It mediates the interaction by providing a controlled stopping point that prevents excessive displacement while allowing normal weighing operations. This intermediary structure ensures measurement precision by maintaining proper alignment without requiring complex constraint mechanisms.
