Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal vibration damper design where a single device can handle multiple vibration directions and load types through symmetric positioning of two bolt elements that can be oriented at different angles. The housing contains universal mounting features allowing the same damper unit to be deployed in various configurations for different application requirements, eliminating the need for multiple specialized dampers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The vibration damper is segmented into independent functional components including separate bolt elements, damping inserts, and housing sections. This segmentation allows each component to be optimized for specific functions while maintaining overall system simplicity, and enables modular assembly that reduces complexity during installation and maintenance.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If damping inserts with varying material properties are used, then the ability to absorb different types of loads is improved, but the manufacturing complexity is worsened

Engineering Contradiction:

Solution Approach 1:

Different damping inserts are positioned at specific locations within the housing based on the vibration and load characteristics of those regions. Each damping insert is selected with material properties and dimensions optimized for its local function, such as using softer materials for high-frequency vibrations and harder materials for impact loads, while maintaining standardized manufacturing processes for each insert type.

Solution Approach 1:

Multiple damping inserts are merged into a single integrated housing structure that contains all damping elements in a compact arrangement. The housing design combines the mounting structure, damping insert holders, and fastening mechanisms into one unified component, reducing the number of separate parts and simplifying installation while maintaining the vibration absorption benefits of multiple damping inserts.

Inventive Principle:
Principle #5Merging (Combining)
