Sanding Machine Thrust Element Orientation for Edge Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanding machines for panels made of wood, metal, plastic, or the like suffer from low processing precision, particularly at the longitudinal edges of the panel, and require complex and expensive electronic control units to manage the timing of thrust element movements.
Innovation Solution
The sanding machine is designed with thrust elements distributed in a direction parallel to the panel's width, allowing for equal distances and time intervals between detection and movement, simplifying the control unit to calculate a single time interval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If thrust elements are distributed in a direction inclined at angles other than 0° relative to the panel width direction, then the sanding machine can cover a wider area of the panel, but the processing precision at longitudinal edges deteriorates
Solution Approach 1:
The sanding device is divided into multiple independent thrust elements distributed along the conveyor belt direction. Each thrust element can be independently controlled to move between raised and lowered positions, allowing selective sanding of different panel regions while maintaining precision at longitudinal edges through coordinated segmentation of sanding actions
Solution Approach 2:
The thrust elements are arranged in a direction inclined at 45° relative to the panel width direction, introducing a diagonal sanding dimension that covers both longitudinal and transverse surfaces. This angular arrangement enables comprehensive panel coverage while the independent control of each thrust element compensates for precision requirements at specific edges
2Ease of operation
If contact rollers and thrust elements are distributed in different directions, then each component can be optimally positioned, but the electronic control unit becomes complicated and expensive due to multiple different time intervals
Solution Approach 1:
The control system merges the timing calculations for multiple thrust elements into a unified approach. Since all thrust elements are distributed in the same direction (inclined at 45°) rather than different directions, they share common timing characteristics, allowing the electronic control unit to use a standardized time interval calculation method for all elements, thereby reducing complexity
Solution Approach 2:
The invention changes the distribution parameter of thrust elements from being in different directions to being in the same inclined direction. This parameter change ensures that all thrust elements have identical geometric relationships with the panel, allowing the control system to use uniform timing parameters rather than multiple different time intervals, simplifying the electronic control unit
