Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardboard working machines are inefficient in producing complex blanks due to laborious configuration requirements, high material waste, and limited flexibility, leading to slow production and unnecessary manual intervention.
Innovation Solution
A machine with transversal translation means and longitudinal positioning systems, featuring motorized tool arms and pneumatic actuators, allows for simultaneous operations like cutting and creasing without stopping the cardboard, enabling flexible production of various shapes and dimensions with minimal waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional punching or cutting machines are used to produce complex blanks, then the machine can perform transversal working operations, but the production speed is slow due to stopping the cardboard for each single operation
Solution Approach 1:
The patent applies the continuity of useful action principle by enabling multiple transversal working operations to be performed simultaneously on the cardboard sheet while it continues moving through the machine. The longitudinal positioning means allow different tool means to operate at different longitudinal positions without stopping the cardboard flow, maintaining continuous productive action throughout the working process.
Solution Approach 2:
The patent segments the transversal working operations into multiple independent operations that can be performed simultaneously at different longitudinal positions. Each tool mean can execute its specific operation (cutting, punching, creasing) independently while the cardboard moves continuously, dividing the overall working process into parallel operations rather than sequential ones.
2Adaptability or versatility
If traditional machines are configured for different blank types, then the machine can produce various blanks, but the regulation and configuration operations become laborious and complex requiring specialist staff
Solution Approach 1:
The patent applies dynamics by making the tool means and their positioning adjustable along the longitudinal direction of the cardboard flow. The longitudinal positioning means enable the tool means to be dynamically repositioned for different blank types without complex reconfiguration, allowing the system to adapt to various production requirements through simple positional adjustments rather than complex regulatory operations.
3Manufacturing precision
If the machine stops the cardboard to carry out transversal working operations, then the tool means can perform cutting or punching operations, but the production time increases proportionally to the blank complexity
Solution Approach 1:
The patent applies preliminary action by pre-positioning multiple tool means at different longitudinal positions along the cardboard path before the cardboard arrives at each position. This allows the cardboard to be worked on continuously as it moves through the machine, with each tool mean already in position to perform its operation at the appropriate moment, eliminating the need to stop for positioning adjustments.
