Solution Overview

Problem

Existing material welders are limited by fixed weld beam widths, requiring replacement or different machines for varying weld widths, which increases costs and operator time.

Innovation Solution

A material welder with adjustable heating elements and an actuator device that allows for selective heating and width control, enabling the same machine to produce welds of different widths by heating either the first or second heating elements, or both, and using an actuator to apply force, eliminating the need for multiple machines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a material welder uses a weld beam with a predetermined width, then the welding process is simple and reliable, but the weld width cannot be adjusted for different situations

Engineering Contradiction:
Improveweld width adjustment capabilityVSAvoidmachine configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The weld beam is divided into multiple independent heating elements (first heating element and second heating element) that can be selectively activated. This segmentation allows the welder to produce different weld widths by controlling which heating elements are active, transforming a single fixed-width beam into a multi-functional heating system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a static, fixed-width weld beam to a dynamic configuration where heating elements can be selectively activated. The controller enables dynamic adjustment of weld width by activating different combinations of heating elements based on the required weld width, making the system adaptable to various welding situations.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple weld beams with different widths are used to accommodate varying weld width requirements, then all weld width requirements can be met, but the cost and operator time increase due to replacing beams or using different machines

Engineering Contradiction:
Improveweld width varietyVSAvoidbeam replacement time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

A single weld beam structure is designed to perform multiple functions by incorporating several independent heating elements. This universal design allows one beam to replace multiple specialized beams, enabling the same machine to produce welds of different widths without requiring physical beam replacements or different machines.

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

Solution Approach 2:

The heating elements are pre-configured in the weld beam structure, ready for selective activation. The controller can immediately switch between different heating element combinations to produce different weld widths, eliminating the time required for beam replacement that would be necessary in a system requiring multiple physical beams.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple weld beams with different widths are used, then all weld width requirements can be met, but the overall cost increases due to purchasing and maintaining multiple beams or machines

Engineering Contradiction:
Improveweld width optionsVSAvoidmachine cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The weld beam is designed as a universal component with multiple heating elements that can accommodate various weld width requirements. This single multi-functional beam replaces the need for multiple specialized beams or machines, reducing the overall equipment investment and maintenance costs while providing the same level of weld width versatility.

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

Solution Approach 2:

Multiple heating functions are merged into a single weld beam structure. By combining several heating elements into one integrated beam with a common support structure and control system, the design achieves the functionality of multiple beams while reducing the total number of components, simplifying the machine configuration, and lowering costs.

Inventive Principle:
Principle #5Merging (Combining)
