Lockable Guiding Device for Soil Compaction Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guiding devices for soil compaction tools lack a secure and easy mechanism to transition the guide pole from a working position to a vertical transport position, risking accidental detachment and injury, especially under high forces during operation or transport.
Innovation Solution
A guiding device featuring a deformable spring element connected to a support member, allowing the guide pole to be securely locked in the working position and easily pivoted to the transport position using a pedal-activated force transmission element, with a damping effect to prevent unintentional lowering, and a securing mechanism to enhance safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guide pole is left in the working position during transport, then the operator can access it easily, but it occupies additional space and risks accidental detachment
Solution Approach 1:
The guide pole is designed to be dynamically repositionable between a horizontal working position and a vertical transport position. The deformable spring member enables this dynamic transformation, allowing the guide pole to adapt its configuration based on operational requirements, thus resolving the contradiction between accessibility and space occupation.
2Volume of moving object
If the guide pole is pivoted to a vertical position for transport, then space is saved, but the locking mechanism may release under high forces during operation
Solution Approach 1:
The deformable spring member serves as a cushioning element that absorbs and dampens forces acting on the locking mechanism. By incorporating this spring element beforehand into the locking system, the patent prevents unintended release of the guide pole even when subjected to high forces during operation, thus maintaining reliability while enabling compact transport position.
3Device complexity
If a simple locking mechanism is used for the guide pole, then the device complexity is reduced, but it cannot prevent accidental folding under high forces
Solution Approach 1:
The locking mechanism is designed to be self-servicing through the deformable spring member that automatically engages and disengages the locking position based on force conditions. The spring element inherently provides the locking function without requiring additional complex components or active control systems, thus achieving high reliability with minimal added complexity.
4Reliability
If the guide pole is locked securely in the vertical position, then accidental lowering is prevented, but it requires a complex activation mechanism for position change
Solution Approach 1:
The system uses the operator's body weight and natural leg movement to activate the position transition through the pedal-actuated force transmission element. This self-service approach eliminates the need for complex motorized or hydraulically actuated mechanisms, achieving reliable position changes using simple mechanical elements that leverage human motion.

AI summary
Guide device (200) for guiding a work implement (210) with a drawbar bracket (220) serving as a connecting element, a drawbar (230) serving as a drawbar element, which is connected to the drawbar bracket (220), is movable relative to the drawbar bracket (220) into a first position or a second position and can be connected to the work implement (210) via the drawbar bracket (220); and a hook (240) serving as a support element, which is connected to the drawbar bracket (220) via a deformable spring element (250) and holds the drawbar (230) in the first position by supporting the drawbar (230) on the hook (240). In this case, the spring element (250) can be deformed by moving the hook (240) and the drawbar (230) can be pivoted into the second position after deformation of the spring element (250).
