Solution Overview

Problem

Existing scraping assemblies for wood panels face issues with collision risks due to scissors or clamp units inserted within the feeding path and damage risks from oscillating blades dragging on delicate edges, leading to potential tool breakage.

Innovation Solution

A scraping assembly with detaching devices mounted outside the feeding path, utilizing a clamp unit with a movable jaw system to separate chip rods from panels, eliminating collision risks and preventing damage to finishing edges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If scissors or clamp units are inserted within the feeding path to detach chip rods, then detaching function is achieved, but collision risk with panels increases

Engineering Contradiction:
Improvechip rod detaching functionVSAvoidcollision risk with panels
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The detaching device is relocated from the horizontal feeding path dimension to a vertical positioning dimension. The clamp unit is positioned above the feeding path and actuates vertically to grasp and detach chip rods, eliminating horizontal collision risks while maintaining detaching functionality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

A vertical positioning mechanism acts as an intermediary between the panel feeding system and the clamp unit. This intermediary controls the vertical movement and positioning of the clamp unit, enabling precise timing and location of chip rod detachment without interfering with the horizontal panel feeding path.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If oscillating blade is used to cut chip rods by dragging on finishing edge, then cutting function is achieved, but damage risk to delicate edges increases

Engineering Contradiction:
Improvechip rod cutting functionVSAvoiddamage to finishing edges
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The harmful dragging action on the finishing edge is completely removed from the system. The oscillating blade mechanism is replaced with a clamp unit that grasps the chip rod at its base and detaches it vertically, extracting the damaging contact between the detaching device and the delicate finishing edge.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical dragging and cutting action of the oscillating blade is replaced with a vertical grasping and detaching action of the clamp unit. This substitution changes the mechanical interaction from horizontal dragging along the edge to vertical extraction at the chip rod base, eliminating edge damage.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If detaching device is positioned outside the feeding path, then collision risk is reduced, but accessibility to chip rods decreases

Engineering Contradiction:
Improvecollision risk reductionVSAvoidaccessibility to chip rods
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The detaching device operates in the vertical dimension rather than the horizontal feeding path dimension. The clamp unit moves vertically above the panel to access and detach chip rods, maintaining reliability by staying outside the horizontal feeding path while preserving accessibility through vertical positioning.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

A vertical positioning mechanism serves as an intermediary that enables the clamp unit to reach the chip rods from above. This intermediary system coordinates the vertical movement to ensure precise positioning over the chip rod base, maintaining accessibility without compromising the horizontal feeding path clearance.

Inventive Principle:
Principle #24Intermediary (Mediator)
