Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a closure device uses only form-fit portions for engagement, then the device can be simple in structure, but it cannot withstand great loads and may inadvertently open under stress
Solution Approach 1:
The closure device is divided into two independent closure parts, each with its own form-fit portion and magnetic element. This segmentation allows each part to be optimized independently while working together to provide both simplicity and high load-bearing capacity through the combination of mechanical engagement and magnetic reinforcement.
Solution Approach 2:
The invention merges two closure parts with complementary form-fit portions and magnetic elements into a unified closure system. The mechanical form-fit engagement provides structural strength while the magnetic elements add holding force, creating a composite closure mechanism that withstands great loads without requiring complex single-part designs.
2Reliability
If magnetic elements are added to support closure engagement, then the closure can withstand greater loads, but the device becomes more complex
Solution Approach 1:
Magnetic elements are introduced as intermediary components between the two closure parts. These magnets act as mediators that provide additional holding force and engagement security without requiring direct mechanical modification of the form-fit portions, thus enhancing reliability while maintaining relatively simple overall structure.
Solution Approach 2:
The closure device uses a composite approach combining mechanical form-fit portions with magnetic elements. This composite closure mechanism integrates two different types of engagement (mechanical interlocking and magnetic attraction) to achieve high reliability and load-bearing capacity while keeping each individual component relatively simple.
3Strength
If the closure device is designed for high load-bearing capacity, then it can safely carry great loads, but it becomes difficult to open intentionally
Solution Approach 1:
The closure device employs dynamic elements including elastically shiftable form-fit portions and pivotally arranged force introduction elements. These dynamic components allow the closure to maintain strong engagement under load while enabling easy intentional opening through minimal actuation force that triggers the elastic and pivotal movements to disengage the form-fit portions.
Solution Approach 2:
The closure mechanism utilizes parameter changes in the form-fit portions that can elastically shift between engaged and disengaged positions. Under normal conditions, the form-fit portions maintain strong engagement, but when a small opening force is applied to the force introduction element, the elastic parameters change allowing the form-fit portions to shift and release, enabling easy intentional opening despite high load-bearing capacity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The closure device can withstand high loads without inadvertently opening, providing a secure and reliable connection that can be easily opened by shifting or tilting, eliminating the risk of accidental release under load.
Implementation Method 1
a recoil element elastically shiftable along the direction of engagement additionally is arranged on one of the closure parts, which on attachment of the closure parts to each other is elastically movable out of a normal position
Implementation Method 2
Two magnets are mounted on each closure part, in order to ensure that the closure parts cannot inadvertently be released from each other

AI summary
A closure device for connecting to parts with each other is provided. The closure device includes a first closure part which includes a first base body and a first form-fit portion stationarily arranged on the first base body, and a second closure part which includes a second base body and a second form-fit portion stationarily arranged on the second base body. For closing of the closure device the first closure part and the second closure part can be attached to each other, whereby the second form-fit portion of the second closure part can be brought in engagement with the first form-fit portion of the first closure part in a direction of engagement, so that in a closed position the form-fit portions positively are in engagement with each other. A recoil element is arranged on one of the closure parts and is elastically shiftable along the direction of engagement.
