Solution Overview
Problem
Existing blister packaging machines lack the ability to arbitrarily set the relative angle of the outer cover portion to the container main body, which affects usability and stability, especially when opening and closing the container.
Innovation Solution
A covered container manufacturing device with an angle regulator that includes a heating unit to heat the hinge portion and a bending unit to set the relative angle of the outer cover portion to a predetermined angle less than 180 degrees, allowing for precise control and stability enhancements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the outer cover portion is simply bent to close the opening of the container main body, then the manufacturing process is simple, but the relative angle of the outer cover portion to the container main body cannot be arbitrarily regulated
Solution Approach 1:
The patent applies parameter changes by heating the hinge portion to a specific temperature range (80°C to 120°C) to make the resin material pliable, then bending the outer cover portion to the desired angle while hot, and maintaining it in that position during cooling. This allows the relative angle to be regulated to any value less than 180 degrees, transforming the rigid fixed-angle structure into a flexible adjustable-one through temperature-based parameter modification.
Solution Approach 2:
The patent employs preliminary action by pre-heating the hinge portion before bending the outer cover portion. This preliminary heating softens the resin material at the hinge, making it easier to deform and set at the desired angle. The heating is performed first, then the bending action follows, ensuring the material is in the optimal state for deformation before the bending force is applied.
2Ease of operation
If a relatively large relative angle is set to enable the article to be readily taken out, then the ease of operation is improved, but the stability of the covered container deteriorates
Solution Approach 1:
The patent applies dynamics by making the relative angle adjustable rather than fixed. The hinge portion can be heated and bent to different angles depending on the specific usage requirements. For articles that need easy removal, a larger angle can be set; for containers requiring stability, a smaller angle can be chosen. This dynamic adjustability allows optimization of both ease of operation and stability based on the specific application.
3Stability of the object's composition
If a relatively small relative angle is set to prevent abrupt rotation and enhance re-closing ease, then the stability is improved, but the ease of taking out the article deteriorates
Solution Approach 1:
The patent applies parameter changes by allowing the relative angle to be modified through heating and bending the hinge portion. If a smaller angle is initially set for stability but article removal becomes difficult, the hinge can be reheated and the angle increased to improve accessibility. This parameter adjustability resolves the contradiction by allowing optimization based on actual usage feedback.
4Manufacturing precision
If the outer cover portion is bent without temperature control, then the manufacturing process is simple, but the relative angle varies among produced containers
Solution Approach 1:
The patent applies parameter changes by controlling the temperature of the hinge portion within a specific range (80°C to 120°C) during the bending process. This temperature control ensures consistent material properties and bending characteristics across all containers. The heating is applied uniformly and maintained for a sufficient duration to ensure complete softening, then the angle is set and maintained during cooling, guaranteeing angle consistency while using energy efficiently through targeted localized heating.
