Fibrous Cleaning Item Assembly for Detachable Gripper Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning tools with fibrous materials face issues such as fixed handles, lack of gripper attachment/removal functionality, and complex heat-sealing processes that reduce strength and increase manufacturing costs.
Innovation Solution
Separate manufacturing of brush and inserted parts with a joining member like adhesive or hot-melt for easy assembly, allowing for flexible design and reduced heat-sealing complexity, enabling efficient and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heat-sealing is used to join fiber bundles, base material sheet and retention sheet in a completely layered state, then the components are firmly joined, but the manufacturing process becomes complex and requires fine adjustment of temperatures and pressure
Solution Approach 1:
The invention divides the cleaning item into separate components (brush part and inserted part) that are manufactured independently and then joined. This segmentation allows each part to be optimized separately and simplifies the overall manufacturing process by avoiding the need to heat-seal multiple layers together in a completely layered state.
Solution Approach 2:
The inserted part containing the gripper insertion space is extracted from the complete layered structure and manufactured separately from the brush part. This extraction eliminates the complexity of heat-sealing the gripper insertion space within the layered structure, while maintaining joint strength through separate joining operations.
2Stability of the object's composition
If the brush part, base material sheet and retention sheet are completely layered and joined by heat-sealing, then the structure is integrated, but the tolerance of heat-sealing conditions must be tightly controlled to prevent strength reduction
Solution Approach 1:
By segmenting the cleaning item into separately manufacturable brush part and inserted part, the invention reduces the number of layers that must be simultaneously heat-sealed, thereby reducing the complexity of maintaining tight tolerances on heat-sealing conditions while still achieving stable structural integration.
3Stability of the object's composition
If the handle is fixed to a predetermined position between the sheets, then the cleaning tool is structurally stable, but the gripper cannot be attached or removed
Solution Approach 1:
The invention segments the cleaning item into a brush part and an inserted part, where the inserted part contains the gripper insertion space. This segmentation enables the gripper to be attached and removed by inserting or removing the inserted part, while the brush part remains structurally stable.
Solution Approach 2:
The invention introduces dynamic functionality by enabling the inserted part to be attached and detached from the brush part. This creates a movable and adjustable structure that allows gripper attachment/removal while maintaining structural stability when assembled.
4Strength
If the brush part and inserted part are joined by linear heat-sealing of the entire structure, then the components are firmly connected, but the manufacturing time and cost increase
Solution Approach 1:
By segmenting the cleaning item into separately manufacturable components that are joined through a simplified process, the invention reduces manufacturing time and cost while maintaining firm connection strength between the brush part and inserted part.
