Rotary Fixing Support for Single-Handed Case Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing supports for portable devices do not allow for easy and single-handed detachment from target objects, requiring two hands for disassembly.
Innovation Solution
A fixing support with a rotary base and engaging member that rotates to engage or release a protective shell or outer casing of the portable device onto a target object, enabling single-handed assembly and disassembly by passing an engaging portion through an engaging hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fixing support is used, then the portable device can be fixed onto the target object, but two hands are required for disassembly which reduces ease of operation
Solution Approach 1:
The fixing mechanism transitions from a static locking structure to a dynamic rotary system. The rotary member rotates between locked and unlocked positions, allowing the engaging member to move between engaging and disengaged states. This dynamic operation enables single-handed operation while maintaining secure fixation during use.
Solution Approach 2:
The fixing support is divided into functionally independent components: the rotary member for rotation operation, the engaging member for locking/disllocking, the rotary base for mounting, and the fixing base for structural support. This segmentation allows each component to perform its specific function efficiently and enables easy assembly and disassembly.
2Ease of operation
If the engaging member is always engaged, then the portable device is securely fixed, but the user cannot easily remove it when needed
Solution Approach 1:
The rotary member provides a dynamic switching mechanism between locked and unlocked states. When rotated to the locked position, the engaging member secures the portable device firmly. When rotated to the unlocked position, the engaging member releases, enabling easy detachment. This dynamic state change maintains security during use while enabling easy removal when needed.
Solution Approach 2:
The rotary member acts as an intermediary between the user's rotational input and the engaging member's locking state. By rotating the rotary member, the user controls the position of the engaging member, which in turn controls whether the portable device is locked or unlocked. This intermediary mechanism provides intuitive control over the fixation state.

AI summary
A fixing support is adapted to detachably fix a case onto a target object. The fixing support includes a fixing base, a rotary base, a rotary member and an engaging member. The rotary base is adapted to be assembled to the target object. The rotary member is rotatably disposed in the fixing base, and is fixed to the rotary base so as to rotate with the rotatory base on a rotational axis with respect to the fixing base. The engaging member is movably disposed inside the fixing base to be moved to a releasing position and an engaging position with respect to the fixing base according to the rotation of the rotary member. The engaging member has an engaging portion, and the engaging member is adapted to pass through the engaging hole. When the engaging member is moved to the engaging position from the releasing position with respect to the fixing base, the engaging portion engages a shoulder part of the engaging hole. In addition, a fixing module includes the aforesaid case and the aforesaid fixing support.
