Movable Base Plate Planer for Alignment and Debris Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand and power tools face challenges in maintaining accurate alignment and angle during operations on non-flat workpieces, and debris clogging issues hinder efficient material removal, posing difficulties for casual users and increasing the risk of accidents.
Innovation Solution
A hand or power planer tool with a selectively movable base plate that can pivot or slide to maintain consistent angle and provide access to debris conductions, allowing for easier alignment and debris clearance without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the base plate is fixed relative to the housing, then the tool structure is simple and reliable, but the user cannot maintain accurate alignment on non-flat work surfaces without skilled judgment
Solution Approach 1:
The base plate is made selectively movable relative to the housing, allowing it to be adjusted between fixed and movable states. This enables the user to align the tool accurately on non-flat work surfaces by manually positioning the base plate, while maintaining structural simplicity when the base plate is locked in place during normal operation.
2Ease of operation
If the debris conduit is fully enclosed, then debris is directed away from the user effectively, but the conduit becomes clogged and difficult to clear
Solution Approach 1:
The debris conduit is segmented into enclosed and open sections. The conduit is partially enclosed to direct debris away from the user during normal operation, while including an open section that allows easy access for clearing blockages without requiring disassembly or specialized tools.
3Ease of operation
If the cutting blade is positioned close to the blade housing, then the tool profile is compact, but access for clearing blockages is restricted and hazardous
Solution Approach 1:
The debris conduit is extracted from the enclosed housing to create an open section that provides access to the cutting blade area. This allows users to clear blockages safely without inserting hands or tools into the hazardous area between the blade and housing, while maintaining a compact overall tool profile.

AI summary
A hand or power tool which can be used as a planer such that the movement of the tool along a workpiece causes a portion of the material of the workpieces to be removed by at least one cutter blade provided on the tool at a baseplate of the tool which contacts with the workpiece. The tool is provided with at least one movable portion which can be moved with respect to the baseplate and hence the tool. The movable portion can be angularly movable to allow a chamfer cut to be accurately achieved and/or can be slidably movable with respect to the baseplate so as to protrude from an edge thereof to allow greater cutting accuracy to be achieved. In a further embodiment the movement portion can be provided so as to be moved to allow user access to at least one debris conduit.
