Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface trimming planes struggle to accurately trim the surface layer of wood boards with curved, oblique, or angled peripheries due to a lack of adjustable cutting blades, necessitating the replacement of different blade sizes for various working conditions.
Innovation Solution
A surface trimming plane featuring a holder with an inner stepped face, a movable nut, an adjusting screw, and a press plate, allowing for microadjustment of the blade's position through rotational movement, enabling precise trimming and cutting of surface layers with different angles and shapes without requiring multiple blade sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional surface trimming plane with a fixed cutting blade is used, then the structure is simple, but it cannot accurately trim wood boards with curved, oblique, or angled peripheries
Solution Approach 1:
The cutting blade is made adjustable through a micrometer screw mechanism that allows the blade to move forward and backward along the guide rail. This dynamic adjustment capability enables the blade to adapt to different trimming depths and angles, resolving the contradiction between trimming accuracy and structural simplicity by introducing a controlled degree of complexity that directly enables precision work on curved and angled surfaces
2Adaptability or versatility
If multiple cutting blades of different sizes are used for different working conditions, then trimming accuracy for various shapes is improved, but device complexity and operation time increase due to blade replacement
Solution Approach 1:
A single cutting blade is designed to perform multiple functions through the micrometer adjustment mechanism. The blade can be positioned at different depths and angles to trim various shapes including curved, oblique, and angled peripheries. This universal blade design eliminates the need for multiple specialized blades, reducing both device complexity and the time required for blade replacements while maintaining adaptability to different working conditions
3Measurement precision
If the cutting blade has a minute adjustment function, then trimming precision is improved, but device complexity increases
Solution Approach 1:
A micrometer screw mechanism serves as an intermediary device between the operator and the cutting blade. The micrometer screw converts rotational motion into precise linear displacement of the blade along the guide rail. This intermediary mechanism provides minute adjustment capability with high precision while maintaining relatively simple construction, resolving the contradiction between measurement precision and device complexity by using a well-established mechanical principle

Implementation Method 1
The adjusting screw extends through the perforation of the holder, and is screwed through the movable nut. The adjusting screw is rotatable in the perforation of the holder. When the adjusting screw is rotated, the movable nut is moved in the guide channel of the holder by rotation of the adjusting screw

AI summary
A surface trimming plane includes a holder, a blade, a press plate, a movable nut, and an adjusting screw. The holder is provided with an inner stepped face which is provided with two tracks, a guide channel and a perforation. The movable nut is mounted in the guide channel. The adjusting screw extends through the perforation, and is screwed through the movable nut. The blade is located between the two tracks and is secured on the movable nut. The press plate is mounted on the holder and located above the blade. The press plate presses the blade to locate the blade. When the adjusting screw is rotated, the movable nut is moved in the guide channel, and the blade is moved with the movable nut to adjust a displacement of the blade.
