Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held tillage implements without motors have low cleaning performance due to saturation with dirt and inability to maintain consistent quality, while motorized versions are bulky and inflexible, making them inefficient in spaces with obstacles.
Innovation Solution
A hand-held tillage device with a motor-driven soil cultivation tool, a guide handle with adjustable joints, and a supply unit that includes a cleaning liquid tank, energy supply, and suction device, allowing for flexible operation in angled or narrow spaces with improved weight distribution and maintenance accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hand-held tillage implements are made motorized to improve cleaning performance, then cleaning performance is improved, but the device becomes bulky and loses flexibility
Solution Approach 1:
The device is divided into separate functional modules: a handheld guide handle section and a detachable supply unit section. This segmentation allows the motorized cleaning function to be concentrated in a compact base while the guide handle remains lightweight and flexible for maneuvering in tight spaces.
Solution Approach 2:
The guide handle employs a multi-section design with sections arranged at different angles and orientations (first section with longitudinal axis, second section connecting to third section with parallel but offset longitudinal axis). This spatial arrangement allows the handle to navigate around obstacles and access narrow areas while maintaining motorized cleaning capability.
2Adaptability or versatility
If hand-held tillage implements without motors are used to maintain flexibility, then flexibility is maintained, but cleaning performance becomes low due to saturation with dirt
Solution Approach 1:
The supply unit is designed with self-contained functionality including integrated cleaning liquid storage, motor power supply, and suction capabilities. This self-service design eliminates the need for external power sources or water connections, allowing the device to maintain high cleaning performance while remaining flexible and portable.
3Adaptability or versatility
If the guide handle sections are arranged with parallel but offset longitudinal axes to improve maneuverability, then flexibility is improved, but device complexity increases
Solution Approach 1:
The guide handle incorporates joints between sections that allow for dynamic adjustment and movement. The connection between the second and third sections enables relative motion while maintaining the parallel offset axis configuration, providing adaptability without requiring complex rigid structures.
