Hydro-Mount Locking Structure for Reusable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydro-mount assembly methods are prone to component damage during disassembly and reassembly, limiting reusability and increasing costs and weights.
Innovation Solution
A hydro-mount assembly structure featuring a locking body with locking portions that engage with fastening grooves on a body plate, allowing for a stable and reusable assembly process using a locking body that can be easily disassembled and reassembled without elastic deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the nozzle assembly and diaphragm are inserted into a pipe in a curling type and the end portion is curled by physical force, then the assembly structure is stable, but the components may be damaged when disassembled for reassembling or analytical purpose
Solution Approach 1:
The locking body is divided into multiple locking portions that can be independently engaged with fastening grooves, allowing the assembly to be segmented for easy disassembly and reassembly without damaging components. This segmentation enables the locking mechanism to be broken down into discrete engagement points rather than a monolithic curled structure.
Solution Approach 2:
The locking portions are designed to be movable between engaged and disengaged states, providing dynamic assembly and disassembly capability. The locking portions can be elastically deformed to release from fastening grooves and recovered to their original shape, enabling repeated assembly cycles without component damage.
2Ease of operation
If a hook member made of plastic or metal is used to fix internal components, then reassembly and disassembly are easy, but the hook member may require various materials increasing degrees of freedom in cost and weight
Solution Approach 1:
The locking body serves multiple functions: it provides structural support, creates damping through fluid pressure, and enables easy assembly/disassembly through its locking portions. This multi-functionality eliminates the need for separate hook members and reduces material selection complexity by consolidating functions into a single component.
Solution Approach 2:
The locking body merges the functions of structural support and fastening into a single component. The body plate and locking body are integrated, combining the roles of container and fastening mechanism, thereby reducing the number of separate parts and simplifying material selection.
3Reliability
If the locking portions are engaged with fastening grooves, then the assembly structure is stable and reusable, but the locking portions need to be moved through recesses which requires precise positioning
Solution Approach 1:
The recesses are pre-formed in the diaphragm and nozzle assembly at specific positions that guide the locking portions during assembly. This preliminary positioning action ensures that the locking portions automatically align with the fastening grooves, reducing the precision requirements for manual positioning and facilitating easier assembly.
