Trolley Tilting Device for Foldable Tool Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling stock equipment for hand tools connected to vacuum cleaners faces challenges in accessibility and bulkiness, particularly with the tilting device occupying volume when not in use, which complicates storage and maneuverability.
Innovation Solution
A tilting device is integrated into the rolling structure, allowing the arm tool support to pivot horizontally and fold, reducing bulk and enabling easy access to the vacuum cleaner unit, with a base secured to the trolley and a mast receiving the support device for articulation, featuring a guide pin and tilting lever for adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tilting device is added to allow articulation of the arm tool support, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The tilting device is nested within the rolling stock equipment structure, with the tilting lever integrated into the base and the arm tool support nested within the mast. This allows the articulation function to be achieved while maintaining a compact overall structure and avoiding excessive complexity.
Solution Approach 2:
The tilting device is segmented into distinct functional components: a base secured to the trolley, a mast receiving the support device, and a tilting lever with guide pin. This segmentation allows each component to perform its specific function independently, simplifying the overall design and maintenance while improving ease of operation.
2Stability of the object's composition
If the tilting device remains in place when not in use, then stability is improved, but volume occupied increases
Solution Approach 1:
The tilting device is designed to be dynamic rather than static when not in use. The tilting lever can be positioned at different angles and locked into place using the guide pin and slot mechanism, allowing the structure to adapt its volume occupation based on operational needs while maintaining stability during storage.
3Ease of operation
If the support device is removably fixed on the mast, then ease of operation is improved, but reliability decreases
Solution Approach 1:
The connection mechanism between the support device and mast is designed to be self-servicing. The guide pin automatically engages with the slot in the tilting lever, and the support device can be easily inserted and removed without requiring additional tools or complex assembly procedures, maintaining both ease of operation and reliable connection.
