Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle top suspension mounts require significant clearance and time for screwing operations, constraining design and assembly efficiency due to the need for external fastening means, which slows down the assembly process.
Innovation Solution
A vehicle top suspension mount with a deformable securing element, such as a tongue, that moves between assembly and securing positions, allowing for secure attachment to a vehicle body without external fastening, facilitating faster and more flexible assembly in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw or bolt fastening is used, then reliable mechanical connection is achieved, but assembly time increases and design freedom is constrained due to required clearance for machine-tool access
Solution Approach 1:
The suspension mount performs the fastening operation itself through its deformable tongue element that automatically engages with the vehicle body housing, eliminating the need for external screw or bolt fastening operations. The mount's own structure provides the fastening function, thereby reducing assembly time while maintaining connection reliability
Solution Approach 2:
The tongue element is designed to be deformable rather than rigid, allowing it to dynamically adjust during assembly and securement operations. This dynamic characteristic enables the tongue to be deformed for insertion and then return to its original position to provide secure mechanical engagement, resolving the contradiction between ease of assembly and connection reliability
2Reliability
If traditional screw or bolt fastening is used, then secure attachment is achieved, but design freedom is reduced due to clearance requirements for machine-tool access
Solution Approach 1:
The fastening function is integrated into the suspension mount structure itself through the deformable tongue element, eliminating the need for separate external fastening means. This self-service approach allows the mount to secure itself within the vehicle body housing without requiring additional clearance for external fastening operations, thereby maintaining attachment security while enhancing design freedom
Solution Approach 2:
The tongue element merges the functions of the suspension mount and the fastening mechanism into a single integrated component. By combining these functions, the invention eliminates the need for separate fastening elements and the clearance they require, thus preserving attachment security while providing greater design freedom and adaptability
3Productivity
If deformable securing element is used, then assembly speed increases and design freedom improves, but structural complexity increases due to the deformable element mechanism
Solution Approach 1:
The tongue element is designed as a flexible, deformable component that can elastically deform during assembly and then return to its original position to provide secure engagement. This flexible element simplifies the overall structure by replacing complex fastening mechanisms with a simple elastic deformation principle, thereby increasing assembly speed without significantly increasing structural complexity
Solution Approach 2:
The tongue element utilizes changes in its physical state (deformation) to achieve different functions during assembly. By changing its shape through elastic deformation, the tongue transitions between insertion and securement phases, enabling fast assembly while maintaining a relatively simple structure that relies on material properties rather than complex mechanical mechanisms

Function Achieved in This Case
The solution eliminates the need for external fastening, enabling quicker and more efficient mounting of the suspension mount, providing greater design freedom and reducing assembly time, while maintaining effective mechanical resistance and ease of implementation.
Implementation Method 1
the securing element is an element that is deformable in relation to the rest of the casing (i.e. the rigidity of which is at least ten times less than the rigidity of the rest of the casing) so that in the assembly position the securing element permits the joining of the top suspension mount to a vehicle body
