Wall Mounting Hook Carriage with Pivoting Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for attaching objects to walls require precise alignment and complex mechanisms, making it difficult to easily fix and remove objects like guitars or screens, especially when using multiple hook-shaped elements, which can be cumbersome and prone to accidental re-engagement.
Innovation Solution
The device incorporates a pivoting and sliding carriage mechanism that allows the second hook-shaped element to be locked in a detached position, enabling easy engagement and disengagement without the need for precise alignment, and includes a pulling element to facilitate removal, along with an elongated edge for flexible positioning and a tension spring for defined displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the second hook-shaped element is made slidable to allow easy detachment, then the ease of operation is improved, but the risk of accidental re-engagement increases
Solution Approach 1:
The locking means (spring element and cam surface) proactively prevents accidental re-engagement by maintaining a disengagement state. The spring element biases the second hook-shaped element away from the wall element, creating a preliminary counter-action that stops unintended connection before it can occur.
Solution Approach 2:
The carriage acts as an intermediary mechanism between the second hook-shaped element and the wall element. It controls the engagement and disengagement process through its interaction with the cam surface, mediating the connection state and preventing direct accidental re-engagement of the hook with the wall.
2Strength
If multiple hook-shaped elements are used to secure heavy objects, then the strength is improved, but the device complexity increases
Solution Approach 1:
The carriage merges multiple functions into a single component: it guides the second hook-shaped element, provides the locking mechanism through interaction with the cam surface, and controls the engagement sequence. This consolidation reduces the number of separate parts while maintaining the strength provided by multiple hook elements.
Solution Approach 2:
The carriage serves multiple purposes: it acts as a guide for the second hook-shaped element, provides locking functionality through the cam surface interaction, and enables controlled disengagement. This multi-functionality reduces overall device complexity while supporting the use of multiple hook elements for enhanced strength.
3Manufacturing precision
If precise alignment is required for hook engagement, then the manufacturing precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The carriage is designed to move dynamically during engagement, transitioning from a retracted position to an extended position as the second hook-shaped element engages with the wall element. This dynamic movement compensates for alignment variations, allowing engagement without precise initial positioning while maintaining manufacturing precision standards.
Solution Approach 2:
The engagement process utilizes parameter changes in the carriage position and orientation. As the carriage moves along the cam surface, its position parameters change to accommodate slight misalignments, enabling successful engagement without requiring high precision in the initial positioning of the hook elements.
