Tape Supplying Body Anti-Running Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In tape supplying bodies for tape printing apparatuses, there is a risk of the tape roll becoming loosened during transportation or installation, leading to the tape running onto or dropping from the roll, which can cause printing failures.
Innovation Solution
A tape supplying body design featuring a first member with a tape roll and a second member that includes a running-onto prevention part at the tape roll's upper surface, a tape receiving part at the first member's bottom surface, and a connection part on the radially outer side to prevent the tape from running onto or dropping from the roll, with the position of the running-onto prevention part adjusted based on the tape width to prevent issues related to tape width variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tape roll is made loose to facilitate tape feeding, then the tape can be fed more easily, but the tape may run onto or drop from the roll during transportation or installation
Solution Approach 1:
The patent applies preliminary anti-action by providing prevention parts (running-onto prevention part and dropping prevention part) before the actual problem occurs. These parts are positioned to preemptively stop the tape from running onto the roll or dropping during transportation or installation, thus preventing the harmful effect before it can manifest.
Solution Approach 2:
The patent uses intermediary structures (connection parts and prevention parts) that mediate between the tape roll and the external environment. These intermediaries protect the tape from harmful effects during transportation while allowing normal feeding operation, thus resolving the contradiction between ease of operation and reliability.
2Reliability
If the running-onto prevention part is positioned closer to the feeding start position, then it can prevent tape from running onto the roll, but it may interfere with tape feeding for wider tapes
Solution Approach 1:
The patent applies local quality by making the running-onto prevention part have different characteristics at different locations. Specifically, the prevention part is designed with a specific position and dimension that is optimized for the local condition of preventing tape from running onto the roll, while the connection part provides a transition zone that adapts to different tape widths, thus resolving the contradiction between prevention effectiveness and adaptability.
Solution Approach 2:
The patent applies dynamics by designing the connection part that can flexibly adapt to different tape widths. The connection part serves as a dynamic element that adjusts its function based on the tape width, allowing the rigid prevention part to maintain its protective function while the system as a whole remains adaptable to different tape specifications.
3Reliability
If the tape roll is secured tightly to prevent loosening, then tape position stability is improved, but the structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the securing function into multiple independent parts: the running-onto prevention part, the dropping prevention part, and the connection part. Each segment performs a specific function, and together they provide comprehensive stability without requiring a complex integrated securing mechanism. This modular approach resolves the contradiction by achieving reliability through simple, separate components.
Solution Approach 2:
The patent applies universality by designing the connection part to serve multiple functions: it connects the prevention parts to the roll, provides structural support, and enables easy assembly and disassembly. This multi-functional design achieves tape roll stability without increasing overall structural complexity, as one component performs several critical roles.
