Blind Retention Mount with Remote Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting methods for inaccessible parts like panels and liners result in excessive wear due to persistent clearances between components, especially in high vibration environments, as they cannot eliminate or reduce these clearances even after installation.
Innovation Solution
A mount assembly featuring a bayonet, main body, and block with an actuation member that allows for remote operation, enabling the reduction or elimination of clearances between components by moving the block along a ramp within the internal cavity to capture or release the bayonet, thus facilitating assembly and disassembly without direct access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If clearances are built into mounting device pieces to facilitate installation of inaccessible parts, then ease of operation is improved, but excessive wear occurs due to persistent clearances after mounting
Solution Approach 1:
The mounting device employs a dynamic clearance adjustment mechanism where the block can be remotely actuated to move between positions. In the first position, clearances are maintained for easy installation; in the second position, clearances are eliminated to prevent wear during operation. This dynamic transition resolves the contradiction between installation ease and operational reliability.
Solution Approach 2:
The invention changes the parameter of clearance distance from a fixed value to a variable value that can be adjusted between two states: a larger clearance for installation and a minimal or zero clearance for operation. The actuation member enables remote control of this parameter change, allowing the system to optimize for different operational phases.
2Ease of manufacture
If conventional fasteners are used for inaccessible mounting locations, then ease of manufacture is improved, but accessibility for installation deteriorates
Solution Approach 1:
The invention extracts the actuation mechanism from the main mounting body, allowing it to be operated remotely from accessible locations. The actuation member extends through the mounting device structure, enabling operators to control clearance adjustment without needing direct access to the mounting location itself.
Solution Approach 2:
The actuation member serves as an intermediary mechanism that transmits force or motion from an accessible remote location to the block inside the inaccessible mounting area. This intermediary enables control of the clearance adjustment without requiring direct access to the mounting location.
3Ease of operation
If clearances are maintained in mounting device pieces, then ease of operation during installation is improved, but excessive wear occurs during high vibration operation
Solution Approach 1:
The system dynamically adjusts clearance parameters based on operational phase: maintaining larger clearances during assembly for ease of operation, then eliminating clearances during high-vibration operation to prevent wear. The remote actuation mechanism enables this dynamic adaptation to different operational conditions.
Solution Approach 2:
The invention applies preliminary anti-action by eliminating clearances before high-vibration operation begins. The block is actuated to the second position in advance, positioning it to contact the bayonet and prevent any relative movement that would cause wear during subsequent vibration exposure.
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 solution reduces wear on the mount assembly components by eliminating or minimizing clearances, making the assembly more accessible and durable, even in situations where direct access is not feasible, and allows for remote actuation to facilitate installation and disassembly.
Implementation Method 1
a block disposed within the internal cavity and movable relative to the main body between a first position and a second position, wherein in the first position the bayonet is captured and held between the block and an inner wall of the internal cavity

AI summary
A mount assembly (10) includes a main body (18), a bayonet (22), and a block (20). The bayonet is movable relative the main body to insert a portion of the bayonet into an internal cavity (26) of the main body. The block is disposed within the internal cavity and is movable relative to the main body from a first position to a second position. In the first position, the bayonet is captured and held between the block and an inner wall (46) of the internal cavity. In the second position, the block allows the bayonet to be removed from the internal cavity.
