Set of a self-adhesive mat and a vessel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-piece sets comprising a self-adhesive mat and a vessel are prone to easy detachment, posing a risk of the vessel being tipped over or dropped, especially by small children, and have cumbersome handling and large storage requirements due to their elastic nature and size.
Innovation Solution
A lockable connection device is introduced, which requires increased force to detach the vessel from the mat, featuring a pluggable connection with a rotating mechanism, a twist lock, or snap lock, and a raised edge to prevent accidental detachment, allowing separate storage and cleaning of the mat and vessel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-piece set with a self-adhesive mat and vessel is used, then the mat can be easily detached and repositioned, but the vessel can be easily detached from the mat by small children, posing a safety risk
Solution Approach 1:
The connection device transitions from a static adhesive bond to a dynamic mechanical locking system. The locking mechanism allows the connection to adapt between securely locked (preventing accidental detachment by children) and easily released (allowing intentional separation for cleaning or storage) states, resolving the contradiction between security and ease of operation.
Solution Approach 2:
The invention changes the connection parameter from simple adhesive force to a mechanical locking state with defined engagement and disengagement positions. The locking mechanism introduces a new parameter state (locked/unlocked) that provides high security during use but allows easy release when needed, simultaneously addressing both reliability and ease of operation requirements.
2Reliability
If a one-piece device with integrated mat and tray is used, then the connection security is improved, but the handling becomes cumbersome and space requirements increase
Solution Approach 1:
The invention divides the device into separable components (mat and vessel) connected by a locking mechanism, rather than integrating them into a single rigid structure. This segmentation allows each component to be handled independently for cleaning and storage, reducing handling complexity while the locking mechanism maintains connection security during use.
Solution Approach 2:
The connection device allows the vessel to be nested onto the mat through the locking mechanism, creating a compact configuration when connected. When separated, both components can be stored independently, minimizing space requirements while maintaining structural integrity and connection security when assembled.
3Reliability
If a lockable connection device is introduced, then the security against accidental detachment is improved, but the connection device complexity increases
Solution Approach 1:
The invention replaces complex multi-component locking systems with a simplified mechanical interlocking mechanism. The locking feature integrates directly into the connection structure, using basic mechanical principles (engagement protrusions, locking surfaces) to provide secure connection without requiring additional complex components, thus improving reliability while minimizing added complexity.
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 solution effectively prevents accidental detachment by small children, minimizes space requirements during storage and cleaning, and ensures the mat remains securely adhered to surfaces, enhancing safety and convenience.
Implementation Method 1
when the mat is lifted, a partial vacuum thus forms, whereby the mat adheres to the surface

AI summary
A set including self-adhesive mat and an object such a vessel, for example. The mat is formed at least partially from an elastically deformable material and on a bottom side has a smooth surface, and the object can be releasably fastened to a top side of the mat by a connection device. The connection device includes a receiving element and a connecting piece interacting therewith, which element and piece are in particular embodied such that they can be plugged into one another. To ensure a connection that is unable to be released by a small child, it is provided that the connection device is embodied to be lockable.
