Protective Cover Mount Module Locking Against Accidental Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Holding accessories for portable electronic devices often cause inconvenience due to arbitrary rotation and detachment during use, leading to potential damage and reduced reliability.
Innovation Solution
A holding accessory with a protective cover and a mount module featuring a holder part, guide grooves, and a rocker member that maintains a coupled state through designated rotation and locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mount module is detachably coupled to the protective cover, then ease of operation is improved, but reliability deteriorates due to arbitrary rotation and detachment during use
Solution Approach 1:
The holder part is designed to rotate from an initial position to a locked position, transitioning from a movable state during installation to a fixed state during use. The guide groove constrains the rotation path while the protruding rib provides a stable locked position, achieving both ease of mounting and operational reliability.
Solution Approach 2:
The guide groove acts as an intermediary element between the holder part and protective cover. It guides the rotation movement of the holder part and ensures proper alignment, while the protruding rib engages with the guide groove to maintain the coupled state during use.
2Ease of operation
If the mount module can be arbitrarily separated from the protective cover, then ease of operation is improved, but reliability deteriorates due to accidental dropping and damage
Solution Approach 1:
The coupling mechanism transitions from movable during installation to fixed during use. The holder part rotates into a locked position where the protruding rib engages with the guide groove, preventing accidental detachment while maintaining ease of intentional separation.
Solution Approach 2:
The guide groove and protruding rib structure provides preliminary anti-action against arbitrary rotation and detachment. The geometric constraint of the guide groove prevents the holder part from rotating beyond the designated angle or detaching accidentally, while still allowing intentional separation.
3Ease of operation
If the holder part rotates arbitrarily, then ease of operation is improved, but reliability deteriorates due to unstable positioning
Solution Approach 1:
The holder part allows dynamic rotation during installation from the initial position to the locked position, providing ease of operation. Once locked, the protruding rib engages with the guide groove to provide stable, accurate positioning that prevents arbitrary rotation during use.
Solution Approach 2:
The guide groove has an asymmetric cross-sectional shape that matches the protruding rib. This asymmetric geometry allows rotation in one direction during installation while preventing rotation in the opposite direction during use, ensuring stable positioning.

AI summary
A holding accessory includes a protective cover including a module mounting part including a protruding rib, a mount module mounted on the module mounting part and including first and second surfaces facing in opposite directions. The mount module includes a holder mount including a holder part disposed on the first surface and having a guide groove formed therein to receive the protruding rib, a cover disposed on the second surface, and a holding structure. The holding structure is at least one of movably disposed on the cover and movably disposed on the holder mount. A locker member is slidably disposed between the holder mount and the cover and maintains the coupled state of the mount module. When the holder mount is mounted and then rotated at a predetermined angle, the mount module may be coupled to the protective cover whereby the protruding rib is seated in the guide groove.
