Self-levelling Equipment Side Plate Transverse Constraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-levelling milling machines face instability due to vibratory transverse forces, which affects the engagement of the adjustment frame with the main frame, leading to precision and stability issues during the manipulation of solid surfaces.
Innovation Solution
The self-levelling equipment incorporates a side plate constrained to second pins, which prevents transverse translations between the frame and support means, ensuring stable engagement and maintaining constant manipulation depth through a compliant connection system involving a first pin, transmission element, and arm, allowing for precise control of the manipulation depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjustment frame is engaged with the main frame using engagement pins and slots, then the adjustment frame can be positioned and adjusted, but the engagement becomes unstable under vibratory transverse forces
Solution Approach 1:
The patent introduces a side plate that constrains the engagement pin in a direction transverse to the main engagement slot. This adds a dimensional constraint (transverse direction) to the existing engagement mechanism, preventing transverse movements and stabilizing the connection under vibratory forces while maintaining the adjustment capability along the slot direction.
Solution Approach 2:
The side plate acts as an intermediary element between the engagement pin and the frame structure. It provides additional support and constraint to the engagement pin, mediating the transverse forces and preventing instability without interfering with the primary adjustment function along the slot.
2Strength
If replacement engagement rails and pins are used to improve engagement, then the connection may be stronger, but the stability under vibratory forces is worsened
Solution Approach 1:
Instead of merely strengthening the existing engagement components, the patent adds a side plate that constrains the pin in the transverse dimension. This dimensional constraint addresses the stability issue under vibration while preserving the adjustment capability, avoiding the need for heavier or stronger but less flexible engagement components.
3Length of moving object
If the support means are lowered to increase manipulation depth, then the penetration depth increases, but the stability and precision of manipulation decreases
Solution Approach 1:
The side plate adds transverse constraint to the support means, preventing lateral movements that would compromise precision. This allows the support means to be positioned at various depths while maintaining stability and precision through the additional dimensional constraint provided by the side plate engagement.
