Solution Overview

Problem

Conventional welding machines for manufacturing batteries experience low productivity due to the high time required for loading and unloading, as the conveyor belt stands still during the welding process, preventing continuous battery transport and processing.

Innovation Solution

A parallel working belt is introduced adjacent to the conveyor belt, with transport slides aligned to enable continuous battery movement between the two belts, allowing for simultaneous transport and welding without conveyor belt standstill, facilitating easier assembly and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the conveyor belt stands still during the welding process to ensure proper positioning and welding quality, then welding precision is improved, but productivity deteriorates due to the loss of time and interrupted continuous transport

Engineering Contradiction:
Improvewelding precisionVSAvoidproductivity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The transport system is segmented into two independent belts: the conveyor belt for loading batteries and the working belt for welding and unloading. This segmentation allows each belt to perform its specific function independently, enabling continuous operation without interrupting the welding process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a single linear transport sequence to a two-dimensional parallel transport system with overlapping operations. The conveyor belt and working belt operate simultaneously in parallel, creating an overlapping time-space structure that eliminates idle periods.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the conveyor belt operates continuously without stopping to maintain high productivity, then productivity is improved, but manufacturing precision deteriorates due to difficulty in positioning and welding

Engineering Contradiction:
ImproveproductivityVSAvoidwelding precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The welding operation is separated from the transport function. The conveyor belt handles only loading while the working belt handles welding, allowing the welding station to work on stationary batteries without affecting overall continuous transport.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Batteries are pre-positioned on the conveyor belt before being transferred to the working belt. This preliminary positioning ensures proper alignment is achieved before welding begins, maintaining precision while enabling continuous flow.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If a single conveyor belt is used for both loading and unloading to simplify the system structure, then device complexity is reduced, but productivity deteriorates due to the need to stop the belt during welding for loading and unloading operations

Engineering Contradiction:
Improvesystem structureVSAvoidproductivity
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The single conveyor belt is divided into two separate belts with distinct functions: the conveyor belt for loading operations and the working belt for welding and unloading. This segmentation eliminates the need to stop the system for loading/unloading while maintaining relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The working belt serves multiple functions: transporting batteries to the welding station, holding batteries during welding, and transporting welded batteries away. This multi-functionality reduces the need for additional specialized equipment while maintaining high productivity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
