Trimming-Scraping Unit for Wood Edging with Integrated Tool Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trimming-scraping units for wood components face inefficiencies due to the time-consuming process of replacing edging strip scraping tools with glue scraping tools, which reduces output.
Innovation Solution
A trimming-scraping unit design that integrates three pairs of tools - trimming tools, edging strip scraping tools, and glue scraping tools - within a single framework, allowing simultaneous operation without tool changes, with glue scraping tools positioned behind edging strip scraping tools to finish components in a single pass, and controlled by an electronic central unit to prevent jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If edging strip scraping tools are replaced with glue scraping tools, then glue removal function is achieved, but production time increases and output decreases
Solution Approach 1:
The patent combines edging strip scraping tools and glue scraping tools into a single integrated tool assembly that can perform both functions sequentially. The tool includes a scraping element positioned to first scrape the edging strip and then scrape glue from the panel surface, eliminating the need for tool replacement and maintaining continuous operation.
Solution Approach 2:
The tool assembly is designed with multi-functionality to perform both edging strip scraping and glue scraping operations. The scraping element can be positioned at different locations to execute different functions, allowing a single tool to replace multiple specialized tools and maintain productivity while achieving versatile functionality.
2Ease of manufacture
If tool replacement is performed between edging strip scraping and glue scraping, then specialized tools are used for each function, but operational time increases
Solution Approach 1:
The patent merges edging strip scraping and glue scraping capabilities into a single tool assembly, eliminating tool replacement operations. The integrated design allows both functions to be performed sequentially without interrupting the workflow, thus removing the time loss associated with tool changes while maintaining functional specialization through configurable scraping element positions.
3Productivity
If multiple tools are integrated in a single framework, then continuous operation is enabled, but device complexity increases
Solution Approach 1:
The patent integrates multiple scraping functions into a single tool assembly with a unified support structure. The design combines edging strip scraping and glue scraping elements in one framework, enabling continuous operation without tool changes. The complexity is managed through a straightforward mechanical arrangement where scraping elements are positioned at different locations on the same tool body.
Solution Approach 2:
The tool assembly achieves multi-functionality through a universal design that can perform both edging strip scraping and glue scraping. The supporting frame and scraping element configuration allow the same tool structure to execute different functions by adjusting the position or orientation of the scraping element, reducing the need for multiple specialized tool structures.
