Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used to apply labels with a portion protruded in a mountain-shape, then the label can be applied to the article, but the application process becomes complicated and work efficiency decreases
Solution Approach 1:
The label holding unit is divided into a pair of divided bodies that can independently approach and separate. This segmentation allows the device to automatically grasp, fold, and apply the label in distinct stages, eliminating manual manipulation complexity while maintaining productivity
Solution Approach 2:
The folding and applying unit automatically performs the folding and application operations without manual intervention. The divided bodies autonomously approach to fold the label and then apply it to the article, making the system self-sufficient and eliminating the complicated manual application process
2Extent of automation
If the label holding unit uses a pair of divided bodies that approach and separate, then automatic folding and application is enabled, but the device structure becomes more complex
Solution Approach 1:
The pair of divided bodies serves multiple functions: they hold the label, fold it by approaching each other, and apply it to the article. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving high automation
Solution Approach 2:
The divided bodies are designed to be movable, transitioning between separated and approached states. This dynamic structure allows the same components to perform different functions at different times, reducing the number of static parts needed and limiting overall device complexity
3Manufacturing precision
If the movement control unit defines separated position for divided bodies, then the outer end portions of the label can be held, but the control system becomes more complex
Solution Approach 1:
The movement control unit replaces complex mechanical positioning mechanisms with electronic or programmable control. By defining the separated position through control signals rather than mechanical stops or fixtures, the system achieves precise label holding while minimizing the physical complexity of the control system

AI summary
[Object] The object of the present invention is to provide a label application device which can easily perform label applying operation by protruding a portion of the label towards an article in a mountain-shape and automatically applying the label, improving the work efficiency by reducing the operation process as much as possible. [Solution] The label application device includes: a label holding unit 20 comprising of an attracting board 21 provided with a pair of divided bodies 21A and 21B attracting and holding a label L supplied from the label supplying unit 10; a folding and applying unit 30 folding and protruding a portion of a label L held in a mountain-shape forming a folded portion 1, and applying an outer end portion 7, provided next to a folded portion 1 to an article W; wherein the folding and applying unit 30 comprising: a movement control unit 40 controlling the movement of the air cylinder unit 31 as a folding unit, wherein the divided bodies 21A and 21B are relatively approaching and separating the other and the label L is folded forming the folded portion 1 by the divided bodies pressing the label L when the divided bodies approach the other, defining the divided bodies at the separation position J when attracting and holding the label L, and at a folded portion forming position K by approaching the divided bodies from the separation position J.
