Solution Overview

Problem

Existing coil material supplying apparatuses face challenges in mitigating fluttering caused by gravity and inertial forces during high-speed transportation, which limits the ability to transport the coil material at higher speeds and fully exert pressing ability in press working.

Innovation Solution

The plate material supplying apparatus conveys the plate material in a diagonally vertical downward direction, utilizing the weight of the material to avoid deformation and opposition to gravity, and includes a space to mitigate the inertial force effects, thereby reducing fluttering and allowing high-speed transportation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the plate material is conveyed from the vertically lower side to the vertically upper side opposing gravity, then the plate material can be supplied to the press apparatus, but the plate material is hung down by gravity causing fluttering to occur

Engineering Contradiction:

Improvetransportation speedVSAvoidplate material stability

Core Design Contradiction:

SpeedVSStability of the object's composition

Solution Approach 1:

The patent inverts the conventional conveyance direction by transporting the plate material from the vertically upper side to the vertically lower side, utilizing gravity to assist rather than oppose it. This inversion eliminates the hanging down effect and fluttering caused by gravity resistance, allowing high-speed transportation while maintaining plate material stability.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent converts the harmful effect of gravity (which causes fluttering when opposing motion) into a beneficial force by conveying the plate material downward. Gravity now assists the conveyance process, reducing the burden on the drive system and eliminating fluttering, thereby enabling high-speed operation.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Productivity

If the plate material feeding apparatus transports the plate material at high speed intermittently, then press working efficiency is improved, but inertial force is generated causing the plate material to vibrate and fluttering to occur

Engineering Contradiction:

Improvepress working efficiencyVSAvoidinertial force and vibration

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a looper (buffer section) in the conveyance path that absorbs and cushions the inertial forces generated during intermittent high-speed transportation. The looper acts as a buffer that mitigates vibrations and fluttering caused by rapid acceleration and deceleration, enabling high-speed operation while maintaining plate material stability.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Stability of the object's composition

If a looper such as U-shape or S-shape is provided to mitigate fluttering, then fluttering is reduced, but the coil material cannot be transported at further high speed and pressing ability cannot be fully exerted

Engineering Contradiction:

Improvefluttering suppressionVSAvoidtransportation speed

Core Design Contradiction:

Stability of the object's compositionVSSpeed

Solution Approach 1:

The patent inverts the conveyance direction to downward motion, which fundamentally changes how gravity interacts with the plate material. This inversion eliminates the need for complex U-shaped or S-shaped loopers to suppress fluttering, as gravity now assists rather than opposes the motion, enabling high-speed transportation without compromising stability.

Inventive Principle:

Principle #13The other way round (Inversion)
