Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic retaining element is used to hold the support in the retracted position, then the reliability of product retention is improved, but the ecological impact increases due to magnetic materials
Solution Approach 1:
The patent replaces the magnetic retaining element with an elastic retaining element that uses elastic deformation to hold the support in the retracted position. The elastic element deforms under the action of the actuator and returns to its original shape to maintain retention, eliminating the need for magnetic materials while preserving the reliability of product retention.
Solution Approach 2:
The patent changes the physical state and properties of the retaining element from magnetic to elastic. The elastic element utilizes elastic modulus and deformation parameters to provide the retaining force, replacing the magnetic field-based retention mechanism with a mechanically-based elastic recovery mechanism.
2Reliability
If a strong magnetic retaining element is used to ensure reliable product retention, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the magnetic component from the retaining mechanism, isolating the essential retention function and implementing it through a simpler elastic element. This removal of the magnetic component simplifies the device structure while maintaining the reliability of product retention through elastic deformation and recovery.
Solution Approach 2:
The elastic retaining element is designed as a simple, inexpensive component that can be easily manufactured and replaced if needed. The elastic element provides sufficient retention force through its material properties rather than complex magnetic fields, reducing both device complexity and manufacturing costs.
3Force
If a magnetic return system is used to exert restoring force, then the restoring force is improved, but the ecological impact and device complexity increase
Solution Approach 1:
The patent replaces the magnetic return system with an elastic return system that uses elastic deformation to provide the restoring force. The elastic element deforms under compression or tension and returns to its original shape, providing a simple and effective restoring force mechanism without requiring magnetic fields or complex magnetic component assemblies.
Solution Approach 2:
The elastic return element is implemented as a simple, inexpensive component that provides sufficient restoring force through its material elasticity. This approach eliminates the need for complex magnetic return systems while maintaining the necessary force characteristics for reliable product retention and release.

AI summary
The invention relates to a device (100) for packaging a product, especially a cosmetic product, comprising a tube (10) having an open end (12), a support (30) for the product, which support is movable in the tube (10) between a retracted position, in which the support (30) is held by a retaining element (50), and a released position, an actuator (60) that is able to neutralize the retaining element (50) and thereby cause the support (30) to move from the retracted position to the released position as a result of a restoring force, the retaining element (50) being configured to automatically reset when the actuator (60) is not being actuated.
