Planer Pusher Mechanism for Uniform Wood Feeding
Solution Overview
Problem
Conventional planers fail to provide an even pushing force for wood, resulting in inconsistent wood planing due to manual pushing, which lacks uniformity and efficiency.
Innovation Solution
A pusher mechanism where the drive shaft transmits kinetic energy to a movable control portion, synchronously rotating a pushing wheel via a reduction wheel, allowing the wood to be slowly and evenly pushed and planed automatically when the planer cutter rotates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pushing is used to move wood through the planer, then the operation is simple, but the pushing force is uneven and planing consistency deteriorates
Solution Approach 1:
The planer is designed to push itself through the wood using a self-actuating mechanism. The cutter head rotates and engages the wood, automatically propelling it forward without requiring manual pushing, thereby maintaining even feeding force and consistent planing quality
Solution Approach 2:
The manual mechanical pushing system is replaced with an automated mechanical system where the rotating cutter head and associated components (such as drive shafts, gears, and pushing wheels) automatically feed the wood through the planer with consistent force
2Manufacturing precision
If automated pushing mechanism is added to ensure even pushing force, then planing consistency improves, but device complexity increases
Solution Approach 1:
The pushing function is merged with the existing cutter head assembly. The cutter head not only performs cutting but also incorporates components (such as integrated pushing wheels or directly coupled drive mechanisms) that automatically feed the wood, combining multiple functions into one assembly to minimize additional complexity
Solution Approach 2:
The cutter head assembly is designed to perform multiple functions: cutting the wood and simultaneously acting as the driving mechanism that propels the wood through the planer. This multi-functionality eliminates the need for separate pushing mechanisms, maintaining simplicity while achieving consistent feeding
3Productivity
If fast wood feeding is used to increase productivity, then output increases, but planing quality deteriorates due to uneven pushing force
Solution Approach 1:
The automated mechanism ensures continuous and uninterrupted contact between the pushing components and the wood throughout the feeding process. This continuous action maintains constant pushing force without the interruptions or variations that occur with manual feeding, enabling both high speed and high quality planing

Function Achieved in This Case
Ensures consistent and efficient wood planing by providing a uniform pushing force, eliminating the need for manual pushing and enhancing the planing process with automated wood movement.
Implementation Method 1
the drive shaft transmits kinetic energy to the movable control portion to urge the pushing wheel to rotate synchronously
Implementation Method 2
the drive shaft drives the pushing wheel to rotate slowly via the reduction wheel
Implementation Method 3
the wood is pushed slowly and is pressed and pushed by the pushing wheel to be planed automatically
