Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging material web coilers require substantial design effort, are not easily adaptable, and occupy large areas, making them inflexible and inefficient for both Leporello-stack and roll-based packaging supply materials.
Innovation Solution
A drive mechanism utilizing a rotatable gyrating mass, such as a flywheel, stores kinetic energy manually and overcomes coiling resistance without additional energy sources, allowing flexible integration into packaging material conversion devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional coiling device is integrated into a packaging material conversion machine, then coiling function is achieved, but device complexity and area requirements increase substantially
Solution Approach 1:
The coiling function is merged with the existing packaging material conversion machine by utilizing the machine's existing drive shaft and structural components. The coiling device is integrated into the machine's frame structure, combining multiple functions (conversion and coiling) into a single unified system rather than adding a separate standalone coiling machine.
Solution Approach 2:
The drive shaft serves multiple functions: it drives the packaging material conversion process and simultaneously drives the coiling mechanism. The same motor and transmission system performs both conversion and coiling operations, making the system multi-functional and reducing overall device complexity.
2Adaptability or versatility
If a conventional coiling device is added to packaging material conversion machines, then coiling capability is provided, but the machines become more extensive and occupy larger areas
Solution Approach 1:
The coiling mechanism is nested within the existing machine structure. The coiling device is positioned inside or integrated into the machine's frame, utilizing available space rather than requiring additional floor area. Components are arranged concentrically or in nested configurations to minimize spatial footprint.
Solution Approach 2:
The coiling function is arranged in a different spatial dimension or orientation within the existing machine envelope. Rather than extending the machine horizontally, the coiling mechanism utilizes vertical space or rearranges components in three-dimensional space to fit within the original machine footprint.
3Reliability
If known coiler devices are used, then coiling operation is achieved, but flexibility in application to different conversion machines is reduced
Solution Approach 1:
The coiling device is designed with universal mounting interfaces and standardized connection points that can accommodate different packaging material conversion machines. The drive mechanism uses standard shaft couplings and transmission components that can be adapted to various machine types, enabling flexible application across different conversion machine models.
Solution Approach 2:
The coiling mechanism incorporates adjustable and movable components that can be configured for different operating conditions and machine types. The device allows for dynamic adjustment of coiling parameters and mounting positions, providing adaptability to various conversion machine configurations rather than being fixed to a single machine design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick, space-saving coiling of packaging material cushions with minimal disruption, reducing the need for additional energy and facilitating easy integration into existing systems.
Implementation Method 1
A drive mechanism is provided which acts without any supplementary driving energy to overcome coiling resistance forces. In particular, the drive mechanism acts without any electronic or pneumatic drive but utilizes a rotatable gyrating mass, in particular a flywheel, which stores and dispenses kinetic energy supplied manually therefrom exclusively through force of hand.
Implementation Method 2
the rotatable gyrating mass is configured such that rotational energy supplied manually therefrom exclusively through force of hand is utilized as coiling work

AI summary
A drive mechanism for a packaging material web coiler for forming a wound-up packaging material cushion may include a coiler core and a rotatable gyrating mass coupled to the coiler core. The coiled packaging material web is coilable around the coiler core such that the coiled packaging material cushion is detachable from the coiler core. With the rotatable gyrating mass, the coiler core performs at least one complete winding of the packaging material web around the coiler core in response to a manual swing-actuation.
