Locking Device Blocking Piece Retracted Housing Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locking devices have a blocking piece that projects outward in the open position, potentially obstructing connected components and appearing unattractive.
Innovation Solution
The blocking piece is designed to be movably arranged within a housing chamber in a retracted position, automatically extending via magnetic forces when the locking device is closed to engage with a spring lock element, and returning to the retracted position when opened, using magnetic or mechanical pre-stressing means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blocking piece is arranged to project outward to enable locking engagement, then the locking function is improved, but the blocking piece obstructs connected components and appears unattractive in the open position
Solution Approach 1:
The blocking piece is designed as a movable component that can change its position between retracted and extended states. It is arranged movably on the casing within a housing chamber, allowing it to dynamically adapt its configuration based on whether the locking device is open or closed, thereby eliminating obstruction in the open position while maintaining locking capability when needed
Solution Approach 2:
The blocking piece is extracted from its projected position during the open state and returned to the housing chamber. By taking out the blocking piece from its obstructive position when not in use, the design eliminates the harmful effect of obstruction while preserving the locking function when the blocking piece is extended for engagement
2Shape
If the blocking piece is made movable to retract into the housing chamber, then the aesthetic appearance is improved, but additional complexity is introduced in the locking mechanism
Solution Approach 1:
The patent replaces complex mechanical drive systems with magnetic means to control the blocking piece's movement. Magnetic attraction forces the blocking piece into the extended position for locking engagement and magnetic repulsion or spring forces return it to the retracted position, simplifying the mechanism while achieving the desired aesthetic appearance
Solution Approach 2:
The blocking piece is designed to automatically return to its retracted position in the housing chamber after performing the locking function. This self-returning mechanism eliminates the need for manual retraction operations or complex control systems, maintaining simplicity while achieving the aesthetic benefit of a retracted blocking piece
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
This design ensures the blocking piece does not obstruct connected components in the open position, provides a secure locking mechanism, and maintains an aesthetically pleasing appearance by keeping the blocking piece concealed when not in use.
Implementation Method 1
magnetic means, which act between the blocking piece of the first locking part and the second locking part and cause a magnetic force between the blocking piece of the first locking part and the second locking part
Implementation Method 2
a spring lock element which is formed spring-elastic at least in sections

AI summary
Disclosed is a locking device, including a first locking part, having a casing and a blocking piece arranged on the casing, a second locking part, having a spring lock element which is formed spring-elastic at least in sections, and magnetic means, which act between the blocking piece of the first locking part and the second locking part and cause a magnetic force between the blocking piece of the first locking part and the second locking part. To close the locking device the first locking part can be attached onto the second locking part in a closing direction. To release the locking device the spring lock element can be slid in an opening direction directed essentially lateral to the closing direction relative to the blocking piece.
