Cleaning device for a self-propelled soil cultivation device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-propelled floor treatment devices are unable to effectively clean wall sections close to the floor, as their lateral brushes are oriented towards the floor surface and cannot reach exposed end faces or higher areas, leading to manual cleaning being necessary, which contradicts the concept of autonomous cleaning.
Innovation Solution
A cleaning device with a fixing element and a pivoting cleaning element carrier that can be detachably connected to a self-propelled floor treatment device, allowing for autonomous cleaning of wall sections by adjusting its position to avoid obstacles and using textile or brush elements for effective dust and dirt removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning device is made higher to reach wall sections, then wall cleaning capability improves, but the device may get jammed on obstacles
Solution Approach 1:
The pivoting element enables the cleaning element carrier to dynamically adjust its position, allowing it to reach wall sections while maintaining the ability to navigate around obstacles. The pivot mechanism acts as a mechanical compliance feature that prevents jamming.
Solution Approach 2:
The pivoting connection provides a flexible joint between the fixing element and cleaning element carrier, allowing the cleaning device to adapt its configuration during movement, similar to how flexible structures avoid rigid contact with obstacles.
2Device complexity
If cleaning elements are permanently fixed, then structural simplicity is maintained, but maintenance and replacement are difficult
Solution Approach 1:
The cleaning elements are mounted on a separate carrier that can be independently removed and replaced. This modular design maintains overall structural simplicity while enabling easy maintenance of consumable components without affecting the main device structure.
Solution Approach 2:
The carrier is pre-configured with mounting mechanisms that facilitate quick attachment and detachment of cleaning elements. This preliminary preparation of the mounting system enables rapid replacement without complex assembly procedures.
