Push Catch Automatic Opening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-button closures for containers require manual operation to open the lid, which does not provide an automatic opening mechanism, lacking in quality impression for high-value product storage such as jewelry or beverage packaging.
Innovation Solution
A push-button closure design where a spring surrounding the locking bolt is pre-tensioned to automatically open the lid when the button is actuated, with a sleeve guiding the socket to ensure reliable operation and a stop mechanism for captive mounting, allowing the lid to open automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a manual push-button closure is used, then the structure is simple, but the quality impression is insufficient for high-value product storage
Solution Approach 1:
The spring is pre-tensioned in the closed state to store elastic potential energy. When the locking bolt is released by the push button, this pre-stored energy automatically propels the lid open without requiring additional manual intervention, thus achieving automatic opening while maintaining simple structure
Solution Approach 2:
The system uses the pre-tensioned spring to automatically perform the opening action itself once triggered. The spring's stored energy self-propels the lid open, eliminating the need for external power sources or complex actuation mechanisms, thereby maintaining structural simplicity while achieving automation
2Extent of automation
If a spring mechanism is added for automatic opening, then the quality impression improves, but the device complexity increases
Solution Approach 1:
The spring mechanism is integrated with the existing locking bolt and push button structure. The spring surrounds the locking bolt and works in conjunction with the existing components rather than requiring separate mechanisms, thus adding automatic opening functionality while minimizing overall device complexity
Solution Approach 2:
The spring serves multiple functions: it provides the opening force, maintains tension in the closed state, and works with the locking bolt to ensure secure closure. This multi-functionality reduces the need for additional components, thereby limiting the increase in device complexity while achieving automatic opening
3Ease of operation
If the locking bolt is released by the handle, then the lid can open, but manual operation is required which reduces quality impression
Solution Approach 1:
The spring is pre-tensioned during the closing operation to store energy. When the user presses the push button to release the locking bolt, this pre-stored energy automatically propels the lid open without requiring the user to manually pull or lift the lid, thus achieving automatic opening while maintaining ease of operation
Solution Approach 2:
The spring acts as an intermediary between the locking mechanism and the lid. When the locking bolt is released, the spring mediates the transfer of energy to automatically open the lid, eliminating the need for direct manual operation on the lid itself while preserving the simplicity of the push button activation
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 automatic opening mechanism enhances the quality impression of the container by providing a simple and reliable way to open the lid, particularly beneficial for storing valuable items.
Implementation Method 1
the spring surrounding the locking bolt acting on the bushing. In the closed state, the spring is pretensioned, so that when the locking bolt is released by the handle, this tension is released, resulting in the lid opening

AI summary
The invention relates to a push catch (2) for a container (1) with a lower part (11) and a cover (12), said push catch comprising a push element (21) which corresponds to a locking bolt (4). Said locking bolt (4) is at least partially surrounded by a spring (43) which acts on a bushing (44) when the cover is in the closed state. Said bushing (44) can be moved along the longitudinal centre line of the locking bolt (4) and is supported on the lower part (11).
