Solution Overview

Problem

The assembling process of implantable pulse generators is complex, requiring sequential completion of steps, leading to long assembly times and high material and labor costs, with no parallel processing possible, and necessitating complete disassembly for repair, which is inefficient and costly.

Innovation Solution

A modular design for the pulse generator comprising a connection module, generator module, and battery module, allowing independent assembly and replacement of individual components, with integrated electrical connections and wireless charging, reducing assembly time and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a modular design is adopted for the pulse generator, then assembly time and repair efficiency are improved, but device complexity increases

Engineering Contradiction:
Improveassembly timeVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The pulse generator is divided into three independent modules: connection module (1), generator module (2), and battery module (3). Each module can be assembled separately and then connected through standardized interfaces, enabling parallel assembly processes and reducing overall assembly time while maintaining manageable complexity through modular organization.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If sequential assembly is used for the pulse generator, then manufacturing precision is maintained, but productivity decreases

Engineering Contradiction:
Improveassembly precisionVSAvoidassembly efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

By segmenting the device into independent modules with standardized connection interfaces, each module can be assembled and tested separately to ensure precision, then quickly connected to form the complete device. This enables multiple modules to be assembled in parallel without compromising assembly precision.

Inventive Principle:
Principle #1Segmentation

3Reliability

If complete disassembly is required for repair, then reliability is maintained, but loss of time and material increases

Engineering Contradiction:
Improveproduct reliabilityVSAvoidrepair time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The modular design allows individual modules to be independently replaced during repair. If a fault is detected in a specific module, only that module needs to be disassembled and replaced, rather than disassembling the entire device. This significantly reduces repair time and material waste while maintaining product reliability through proper module replacement.

Inventive Principle:
Principle #1Segmentation

4Manufacturing precision

If sequential assembly steps are required, then manufacturing precision is ensured, but loss of time increases

Engineering Contradiction:
Improveassembly qualityVSAvoidassembly period
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The device is segmented into independent modules that can be assembled in parallel sequences simultaneously. Each module maintains its own assembly quality control processes, and the standardized connection interfaces ensure that the final integration maintains overall assembly quality while significantly reducing the total assembly period through parallel processing.

Inventive Principle:
Principle #1Segmentation
