Multi-Implement Hand Tool with Mechanical End-Effector Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning and retrieval tools require separate implements for sweeping, grabbing, and adhesive pick-up tasks, leading to inefficiency in storage and use, and existing multi-function tools lack seamless transitions or require manual reconfiguration.
Innovation Solution
A wand-like hand tool integrating a broom-and-dustpan, grabber, and adhesive foot implement with a mechanical selection mechanism, allowing seamless switching between functions without electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate cleaning tools are used for sweeping, grabbing, and adhesive pick-up tasks, then each tool can be optimized for its specific function, but storage efficiency decreases and users must carry multiple implements
Solution Approach 1:
The patent combines three separate cleaning implements (broom, grabber, and adhesive pick-up tool) into a single integrated wand device. The broom head, grabber mechanism, and adhesive foot are all attached to a common handle, allowing users to perform multiple cleaning tasks with one tool instead of carrying three separate implements.
Solution Approach 2:
The cleaning wand is designed as a universal tool that can perform three distinct cleaning functions. By incorporating a broom for sweeping, a grabber for picking up objects, and an adhesive foot for picking up lightweight items, the single device serves multiple purposes that previously required separate specialized tools.
2Device complexity
If existing multi-function tools are used, then storage efficiency improves, but transitions between functions require manual reconfiguration or disassembly
Solution Approach 1:
The cleaning wand employs dynamic, movable components that allow easy transition between functions. The broom head can be detached and replaced with the grabber or adhesive foot through a simple quick-release mechanism, and the grabber fingers are spring-loaded to automatically open and close, eliminating the need for manual reconfiguration between tasks.
Solution Approach 2:
The device is segmented into modular components (broom head, grabber mechanism, adhesive foot, and handle) that can be independently attached or detached. This segmentation allows users to quickly switch between functions by simply replacing the appropriate head or attachment without disassembling the entire tool.
3Ease of operation
If electronic components are added to enable seamless switching between functions, then ease of operation improves, but environmental impact increases and device complexity increases
Solution Approach 1:
The cleaning wand uses spring-loaded mechanisms that automatically perform the work of switching between functions. The spring-loaded grabber fingers automatically open when the grabber is detached and close when attached, eliminating the need for electronic actuators or motors. This mechanical self-service approach reduces environmental impact while maintaining ease of operation.

AI summary
A manually operated, multi-implement hand tool, featuring a wand with a selectable end-effector system that includes a broom-and-dustpan, a grabber, an adhesive foot, and a magnet for picking up lightweight items. The tool incorporates a purely mechanical selection mechanism utilizing either a rotating carousel with precision ball bearings and gear reduction or a sliding rail system with grooved detents. Each implement includes specialized mechanical features: a spring-loaded folding dustpan with a torsion spring hinge, a grabber with rubberized pads and a compound pulley system providing 5:1 mechanical advantage, and a silicone-based adhesive pad with a pivoting mount and detachment lever. The ergonomic handle integrates all control mechanisms in a central hub with contoured grips and non-slip surfaces. The comprehensive mechanical linkage system uses cables, pulleys, and springs to provide smooth, efficient operation without requiring electrical components. The device offers a synergistic, space-saving solution for diverse cleaning and retrieval tasks.
