Reconfigurable Scoring Head with Slit Discs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scoring machines require disassembly to change configurations of scoring and receiving discs, which is time-consuming and inefficient, as they need to expose shaft ends to reconfigure the discs, leading to downtime in the scoring process.
Innovation Solution
A reconfigurable scoring head system with hubs and support discs that allow scoring discs to be installed and removed without disassembling the machine, using slits and grooved discs to enable flexible positioning and alignment without removing shafts, and utilizing set screws and nuts for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If scoring discs and receiving discs are reconfigured by disassembling the scoring machine to expose shaft ends, then the discs can be changed, but the process takes considerable time and causes downtime
Solution Approach 1:
The scoring head is divided into separable components: the scoring disc, support disc, and hub assembly. The scoring disc can be independently removed from the support disc by bending at the slit, allowing rapid reconfiguration without disassembling the entire machine or removing shafts from the machine frame.
Solution Approach 2:
The scoring disc is extracted as a separate replaceable component from the support disc assembly. The slit in the scoring disc enables it to be bent and removed from the support disc without affecting the hub or shaft, allowing quick changes while the shaft remains installed in the machine.
2Manufacturing precision
If scoring discs are made rigid for precise scoring, then scoring accuracy is maintained, but the discs cannot be easily removed or reconfigured
Solution Approach 1:
The scoring disc has different properties in different regions: the main body is rigid for precise scoring, while a localized slit is introduced to enable flexibility for removal. The slit is positioned strategically to allow bending without compromising the structural integrity of the scoring surface during operation.
Solution Approach 2:
The scoring disc transitions from a static rigid structure to a dynamically adaptable component. The slit enables the disc to be bent and deformed temporarily for removal and installation, while returning to its rigid functional state during scoring operations.
3Adaptability or versatility
If multiple scoring configurations are available, then versatility is improved, but the complexity of the scoring head assembly increases
Solution Approach 1:
Multiple support discs with different groove configurations are pre-assembled on the hub in predetermined positions. This allows rapid selection of different scoring configurations by simply changing the scoring disc or rotating the hub, without requiring complex adjustment mechanisms during operation.
Solution Approach 2:
The hub assembly is designed as a universal platform that can accommodate multiple support discs with different groove patterns. The standardized bore and shoulder design allows different support discs to be interchangeably mounted, providing multiple scoring configurations through a single multi-functional assembly.

AI summary
A first hub having a first outer diameter and a second outer diameter that is larger than the first outer diameter defining a shoulder. A second hub having a first outer diameter and a second outer diameter that is larger than the first outer diameter defining a shoulder. Each hub receiving a corresponding shaft within a bore, the shafts being spaced apart and parallel. A pair of support discs hold a scoring disc having an aperture adapted for fitting over one of the hubs. The scoring disc has a raised profile that stands proud of the support discs. A grooved disc has a bore that is received on another of the hubs. The grooved disc includes a circumferential groove for receiving the raised profile when the scoring disc is aligned opposite the circumferential groove.
