Interchangeable Charging Module for Soil Compactor Battery Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soil processing machines with internal combustion engines do not require external charging, but electrically operated machines need a reliable and flexible interface for recharging batteries.
Innovation Solution
A detachable interchangeable charging module with a suspension arrangement and locking mechanism is integrated into the machine frame, allowing connection to an external voltage source for battery charging, ensuring stability and safety while being usable across multiple machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a charging module is permanently installed on the soil processing machine, then the charging function is stable and reliable, but the device complexity increases and multiple charging modules are needed for different machines
Solution Approach 1:
The charging module is designed as a universal interchangeable unit that can be used across multiple soil processing machines. By standardizing the connection interface and suspension arrangement, a single charging module design serves multiple machine types, eliminating the need for machine-specific charging modules while maintaining reliable charging functionality.
2Ease of operation
If a charging module is detachably supported on the machine frame, then the ease of operation improves and one module can serve multiple machines, but the stability of connection may be compromised
Solution Approach 1:
The charging module employs a dynamic suspension arrangement that allows for easy attachment and detachment while maintaining stable connection during use. The suspension system provides controlled movement for installation/removal operations, then secures the module firmly during charging operations, adapting to different operational states.
Solution Approach 2:
The connection interface uses asymmetric engagement elements with specific geometric features that provide directional guidance and secure locking in the attached state, while allowing easy removal when needed. The asymmetric design ensures proper alignment and stable connection during operation.
3Reliability
If multiple separate charging modules are kept for different soil processing machines, then each machine has dedicated charging capability, but the loss of substance increases due to inventory requirements
Solution Approach 1:
A single standardized charging module design can service multiple different soil processing machines. This universality eliminates the need to maintain an inventory of different charging module types for different machines, reducing material consumption and storage requirements while ensuring charging availability across the machine fleet.
4Reliability
If the charging module is designed with engagement elements for secure attachment, then the connection stability improves, but the device complexity increases
Solution Approach 1:
The suspension arrangement is segmented into discrete functional elements: engagement elements for secure attachment, support regions for positioning, and connection interfaces for electrical contacts. This segmentation allows each element to perform its specific function efficiently while keeping the overall structure manageable and not excessively complex.
