Syringe Label With Pivotable Needle Guard And Weakening Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional syringe needle receiving devices fail to reliably adjust and maintain predefined angular positions after repeated use, leading to potential interference during injection and increased risk of injury from the exposed needle.
Innovation Solution
A label with a first film part wrapped around the syringe body, featuring a needle receiving device with a plastic molded part and a transition area that includes weakening elements, allowing automatic adjustment of angular positions to ensure secure and safe needle protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the needle receiving device is pivotably connected to the first film part through a transition area, then the needle receiving device can be pressed laterally against the syringe needle for protection, but the transition area becomes weakened or damaged after repeated swinging back and forth, failing to reliably ensure automatic readjustment to predefined angular positions
Solution Approach 1:
The patent applies preliminary action by pre-defining specific angular positions through which the needle receiving device can pivot. The transition area is designed with predetermined pivotable positions that guide the device to automatically return to safe angular orientations relative to the syringe needle, even after repeated use. This pre-established geometric constraint ensures reliable readjustment without requiring active control mechanisms.
2Reliability
If the needle receiving device protrudes in the axial direction beyond the shoulder of the syringe body, then it can be pressed against the exposed syringe needle for protection, but it gets in the way during syringe administration
Solution Approach 1:
The patent applies dynamics by making the needle receiving device pivotable rather than fixed. The device can dynamically change its angular position relative to the syringe body, allowing it to protrude for needle protection after use while being able to retract or rotate away during administration. This dynamic positioning resolves the conflict between protection and ease of operation.
Solution Approach 2:
The patent applies local quality by providing the needle receiving device only in the transition area of the label, rather than covering the entire syringe body. The device is strategically positioned to provide needle protection only when needed, while minimizing interference with the syringe body during administration. This localized approach allows the device to serve its protective function without compromising overall ease of operation.
