Cleaning Pad With Replaceable Spray Container Through Core Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cleaning pads with integrated supply bottles are bulky, complex to produce, and difficult to replace, as the outer surfaces of the supply part are plane-parallel to the core, making them inefficient and inconvenient for maintenance.
Innovation Solution
A cleaning pad design where the supply part can be passed through an opening with a congruent cross-sectional area, allowing for simple production and rapid replacement, featuring a core with a cavity formed by punching or welding, and using adhesive material for stable bonding of material blanks to create a durable and visually appealing cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the supply part is arranged voluminously in the core with plane-parallel outer surfaces, then the cleaning pad structure is stable, but the production becomes complex and the supply part cannot be easily replaced
Solution Approach 1:
The cleaning pad is divided into separable components: the core with cavity, the supply part, and the cleaning cover. The supply part can be independently inserted into or removed from the core through the opening, allowing for simple replacement without replacing the entire pad. This segmentation resolves the contradiction by enabling easy maintenance while maintaining structural integrity during use.
Solution Approach 2:
The supply part is extracted from being permanently integrated into the core and is instead designed to be insertable and removable through an opening in the core. This allows the supply part to be taken out for replacement when damaged or depleted, solving the replacement difficulty problem while maintaining a compact structure during operation.
2Ease of repair
If the supply part is made replaceable, then maintenance becomes easier, but the structural stability and tight fit may be compromised
Solution Approach 1:
The supply part is nested within the core structure, with the cavity of the core receiving the supply part. The opening in the core allows the supply part to be inserted and secured within the core's cavity, creating a nested configuration that provides both replaceability and structural stability. The supply part fits tightly within the core when assembled, ensuring reliability during use.
3Ease of operation
If the cross-sectional area of the opening is dimensioned to allow supply part passage, then replacement becomes easy, but the visual appearance may be compromised
Solution Approach 1:
The opening in the core is positioned asymmetrically, preferably at the top of the core, and is dimensioned to match the cross-sectional area of the supply part. This asymmetric placement allows for easy identification and insertion of the supply part while minimizing the visual impact on the overall pad appearance. The opening can be strategically located to be less noticeable from the front view of the cleaning pad.
