Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders for fastening pumps in motor vehicles suffer from instability, leading to potential slippage and complex production and assembly, while also failing to effectively dampen noise and vibrations.
Innovation Solution
A holder design featuring an elastic damping element with an inner and outer ring connected by connecting elements, incorporating a holding element integrated via vulcanization or overmolding, which enhances stability, dampens vibrations, and simplifies assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional holders are used for fastening pumps, then the structure is simple, but the holder loses stability and the pump may slip out
Solution Approach 1:
The holder uses a composite structure combining an elastic damping element (rubber-like material) with holding elements (metal inserts), creating a multi-material system that provides both stability and pump retention through the integration of different material properties
Solution Approach 2:
The holding elements are embedded within the elastic damping element, with metal inserts nested inside the rubber matrix. This nesting approach integrates multiple functions (damping, holding, mounting) into a single composite component, improving stability without proportionally increasing external complexity
2Ease of manufacture
If holding elements are separately mounted into the outer ring, then assembly is complex and costly, but integration methods like vulcanization or overmolding simplify assembly
Solution Approach 1:
The holding elements are merged with the elastic damping element through integral connection methods (vulcanization or overmolding), combining what would traditionally be separate components into a single integrated part. This eliminates separate assembly steps and reduces manufacturing complexity despite the sophisticated integration process
Solution Approach 2:
The material state is changed during integration - the elastic damping element is in a molten or semi-liquid state during vulcanization/overmolding, allowing the holding elements to be embedded, then the material solidifies to create a permanent integral connection. This parameter change enables seamless integration
3Reliability
If the holding element is exposed, then assembly is simple, but the holding element is susceptible to corrosion and wear
Solution Approach 1:
The elastic damping element acts as a flexible protective shell that encloses the holding elements. This rubber-like membrane provides corrosion and wear protection while maintaining the functional integrity of the metal inserts, combining protection with flexibility
Solution Approach 2:
The composite structure of elastic material surrounding metal holding elements creates a protective system where the corrosion-resistant elastic material shields the metal from environmental damage while the metal provides structural strength
4Object-generated harmful factors
If rigid connections are used between rings, then structural strength is high, but noise and vibration transmission increase
Solution Approach 1:
The connection between inner and outer rings changes from rigid to elastic through the use of the elastic damping element. This parameter change in connection rigidity allows the structure to absorb vibrations and noise while maintaining sufficient strength through the elastic properties of the damping material
Solution Approach 2:
The elastic damping element converts the potentially harmful rigid connection into a beneficial vibration-absorbing connection. The elasticity that might seem to reduce structural strength actually provides noise and vibration damping, turning a potential weakness into a functional advantage
