Self-locking hanging device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hardware for hanging objects on surfaces, such as walls, often lacks assurance of proper engagement and can be prone to dislodgment, as it is difficult to confirm that the hanging hardware is correctly aligned and securely attached without specialized tools or equipment.
Innovation Solution
A self-locking device comprising a hanging arm or hook member that slidably mates with a mounting bracket, allowing for rotatable and lockable positions along a track, enabling secure attachment and detachment without specialized tools, and featuring a reconfigurable design from open to closed positions to ensure the object is properly supported and locked in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hanging hardware (nails, screws, hooks) is used, then the object can be attached to the wall, but it is difficult to confirm proper engagement and the hardware may become dislodged
Solution Approach 1:
The hanging device performs self-verification through visual indicators that show whether the object is properly engaged with the wall hardware, eliminating the need for specialized tools or equipment to confirm proper installation
2Ease of operation
If clips or carabineers are used, then the object can be attached, but they typically do not lock the object onto the wall and may become dislodged
Solution Approach 1:
The arm member transitions between movable and locked states, allowing easy attachment and detachment while providing secure locking when engaged, thus combining operational ease with reliability
Solution Approach 2:
The mounting bracket serves as an intermediary component that provides both the attachment interface and the locking mechanism, mediating between the wall hardware and the object to prevent dislodgment
3Reliability
If dual step systems with surface/wall bracket and object bracket are used, then the object can be fixed onto the surface, but they often require specialized tools or equipment
Solution Approach 1:
The device is divided into separate functional components (mounting bracket, arm member, locking mechanism) that can be independently assembled and operated without requiring specialized tools, reducing overall system complexity while maintaining secure attachment
4Reliability
If the arm member is always locked in closed position, then the object is securely held, but the object cannot be attached or removed
Solution Approach 1:
The arm member dynamically transitions between locked and unlocked states, allowing the system to adapt between secure holding mode and attachment/removal mode as needed
5Adaptability or versatility
If the arm member is always open, then the object can be easily attached, but the object is not secured and may become dislodged
Solution Approach 1:
The arm member transitions from an open state that allows easy attachment to a locked closed state that prevents dislodgment, providing both adaptability and reliability at different operational phases

AI summary
A self-locking device for hanging objects on a mounting surface is disclosed. The self-locking device includes a mounting bracket and a locking arm member engaged with a track portion of the mounting bracket. The track portion comprising a pair of guide portions, a pair of lip portions extending from a lower end of the guide portions, a pair of rotation portions extending from an upper end of the guide portions, and a slot extending between the pairs of guide portions, lip portions and rotation portions. The arm member being mated with the track portion such that the arm member is translatable along the track portion. The arm member comprising a tip portion, a base portion positioned at least partially within the slot, and at least one pair of projections extending from the base portion that engage with one of the pairs of guide portions, lip portions and rotation portions.
