Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular control systems lack the ability to efficiently supply multiple series modules with individual voltage levels, which limits their design and increases production and storage costs due to the need for varied module configurations.
Innovation Solution
The implementation of Z-concatenated connecting lines between series modules, allowing for groups of modules to be addressed and supplied with electrical energy independently, while the bus communication line runs parallel through all modules, enabling the use of standardized row modules and providing independent voltage levels through ground and supply line pairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional straight-through connecting lines are used between series modules, then the module design is simple, but multiple individual voltage levels cannot be supplied to different groups of modules
Solution Approach 1:
The connecting lines are segmented into different groups (first group, second group, etc.) where each group can be independently controlled to supply different voltage levels to different groups of series modules. This segmentation allows the system to provide multiple individual voltage levels while maintaining a standardized module design.
Solution Approach 2:
The connecting lines are arranged in a Z-connection pattern instead of a simple straight-through connection, adding a dimensional aspect to the connection topology. This Z-arrangement allows different connecting lines to be grouped and controlled independently, enabling multiple voltage levels without requiring different module hardware configurations.
2Adaptability or versatility
If varied module configurations are used to supply different voltage levels, then individual voltage control is achieved, but production and storage costs increase
Solution Approach 1:
A single standardized series module design is created that can function in multiple voltage level configurations. The module itself remains universal and unchanged, while the Z-arranged connecting lines provide the versatility to supply different voltage levels to different module groups, eliminating the need for multiple specialized module variants.
Solution Approach 2:
Instead of creating physically different module variants for different voltage levels, the solution uses identical module copies with different connecting line group assignments. The Z-connection arrangement allows the same module design to be copied and deployed in various voltage configurations through software or connection routing rather than hardware variation.
3Reliability
If all series modules are supplied with the same voltage level, then the system is simple to control, but safety and flexibility are reduced
Solution Approach 1:
The control system segments the series modules into different groups that can be independently controlled. Each group of modules connected through Z-arranged connecting lines can be supplied with different voltage levels and controlled independently, enhancing safety by allowing selective shutdown or voltage adjustment of specific module groups without affecting the entire system.
Solution Approach 2:
The system transitions from a static, uniform voltage supply to a dynamic configuration where voltage levels and control parameters can be changed for different module groups as needed. The Z-connection arrangement enables this dynamic reconfiguration through software control or connection routing, allowing the system to adapt to different operational requirements and safety conditions.
