Compaction Roller Battery Mounting for Vibration-Stable Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compaction rollers face issues with battery defects due to vertical shake during operation and require heavy lifting for insertion and removal, imposing a significant user load.
Innovation Solution
A compaction roller design with a storage unit allowing battery insertion and removal parallel to a plane passing through the first and second axes, reducing vertical shake and user load by stabilizing the battery and connection terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is installed in the storage unit, then the battery can be securely held during operation, but the battery may experience vertical shake causing electrical system defects
Solution Approach 1:
The patent changes the insertion direction of the battery from the vertical direction to a direction parallel to the plane passing through the first and second axes (horizontal direction). This dimensional change ensures that during vertical compaction operations, the battery experiences minimal vertical movement, thereby preventing electrical connection defects while maintaining secure holding.
2Ease of operation
If the battery is designed for vertical insertion and removal, then the battery can be easily accessed, but the user must lift the heavy battery vertically which imposes large load
Solution Approach 1:
The patent modifies the insertion and removal direction of the battery from vertical to horizontal (parallel to the plane passing through the first and second axes). This allows users to slide the battery in and out horizontally rather than lifting it vertically, significantly reducing the physical load on users while maintaining ease of access and operation.
3Reliability
If the battery is positioned to minimize vertical shake, then electrical stability is improved, but the insertion and removal operation becomes more complex
Solution Approach 1:
The patent achieves electrical stability by orienting the battery horizontally (parallel to the plane passing through the first and second axes) rather than vertically. This simple orientational change minimizes vertical shake during compaction operations while maintaining a straightforward storage unit structure with an opening for horizontal insertion and removal, avoiding unnecessary structural complexity.
