Modular Pulse Generator Assembly for Faster Repair and Production
Find Innovative SolutionsGenerate Solutions
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
Engineering Contradiction Analysis
1Productivity
If a modular design is adopted for the pulse generator, then the assembly time and repair efficiency are improved, but the device complexity increases
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, tested, and replaced independently, enabling parallel assembly processes and reducing overall assembly time while maintaining manageable complexity through standardized interfaces
2Device complexity
If sequential assembly process is used, then the device complexity is reduced, but the productivity decreases
Solution Approach 1:
By segmenting the pulse generator into independent modules with standardized connection interfaces, the assembly process can proceed in parallel for different modules rather than sequentially, significantly improving productivity while the modular structure itself keeps the overall system complexity manageable
Solution Approach 2:
Each module can be pre-assembled and tested independently before final integration, allowing quality control and assembly operations to occur simultaneously across multiple modules rather than waiting for sequential completion
3Device complexity
If complete disassembly is required for repair, then the device complexity is reduced, but the loss of time increases
Solution Approach 1:
The modular design allows damaged components to be identified and replaced at the module level rather than requiring complete disassembly of the entire device, significantly reducing repair time while maintaining simple replacement procedures through standardized interfaces
Solution Approach 2:
Damaged modules can be quickly removed and replaced with functional modules, allowing rapid recovery of device functionality without the need to disassemble and repair individual components within the module
