Solution Overview

Problem

Reloading paper supplies onto paper dunnage producing machines is time-consuming and labor-intensive due to the density and form of the paper, which disrupts the production of paper dunnage and delays shipments.

Innovation Solution

A reloading supply system comprising a loading cart with a combed surface and a machine with a matching combed surface, where the teeth of the cart's surface pass by the machine's surface to transfer sheet paper or fanfold paper reams efficiently, allowing for continuous operation without manual coupling of reams.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual reloading of paper supplies is used, then the machine can be reloaded with paper, but the process is time-consuming and labor-intensive

Engineering Contradiction:
Improvereload speedVSAvoidproduction disruption time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system enables self-service reloading through the interaction between the combed surface teeth on the cart and machine. The teeth automatically engage and transfer paper reams from the cart to the machine without requiring manual handling, allowing the system to reload itself efficiently.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The combed surface teeth act as an intermediary mechanism between the cart and machine. These teeth engage with the paper reams and facilitate automatic transfer, serving as a mediator that eliminates the need for direct manual handling while enabling continuous operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If dense sheet paper is used, then the paper can be compacted for storage, but it becomes labor-intensive to reload

Engineering Contradiction:
Improvepaper storage densityVSAvoidreload effort
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The combed surface teeth automatically engage with the stacked paper reams and transfer them from the cart to the machine. This self-service mechanism eliminates the need for manual lifting and placement of dense paper stacks, making the operation of reloading dense paper supplies easy despite their weight and compactness.

Inventive Principle:
Principle #25Self-service

AI summary

A reloading supply system includes a loading cart (100) and a machine (200). The loading cart has a first material tray (120) that includes a first combed surface (122) configured to retain a supply material in the first material tray. The machine has a second material tray (220) that includes a second combed surface (222) configured to retain the supply material in the second material tray after the supply material is transferred from the first material tray of the loading cart to the second material tray of the machine. Teeth (124) of the first combed surface are configured to pass by teeth (224) of the second combed surface. The first combed surface and the second combed surface are configured such that the supply material in the first material tray is transferred to the second material tray as the teeth of the first combed surface pass by the teeth of the second combed surface.
