Solution Overview
Problem
Existing shock absorber devices face challenges due to complex structures and difficulties in pre-assembly and mounting on support surfaces, as well as the need for solid elastically deformable materials that complicate cavity formation and recess design.
Innovation Solution
A shock absorber device with a casing made of suitable materials like plastic or steel, featuring a stopper arrangement with a rotatable buffer roller supported by springs and a simple assembly process using accessible screws, allowing pre-assembly and easy mounting on a support surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a solid body made of elastically deformable material is used to house the buffer roller, then the damping effect is achieved, but the structure becomes complex and difficult to manufacture
Solution Approach 1:
The solid body is divided into a housing and separate support blocks. The support blocks are movable within the housing, allowing the buffer roller to be supported without requiring complex cavities and recesses to be formed in a single solid body. This segmentation simplifies manufacturing while maintaining the damping function.
Solution Approach 2:
The support blocks are made movable within the housing rather than being fixed as part of a solid body. This dynamic arrangement allows the support structure to adapt to the buffer roller's movement and spring compression, achieving the damping effect through motion rather than through complex fixed geometry.
2Reliability
If insert support blocks with return springs are used for the buffer roller axis, then the buffer roller can be supported, but the device structure becomes complex and pre-assembly is not possible
Solution Approach 1:
The device is segmented into a housing, support blocks, and buffer roller assembly. The support blocks are integrated into the housing as movable elements rather than separate insert blocks, reducing the number of components and simplifying the overall structure while maintaining the support function.
Solution Approach 2:
The support blocks and housing are combined into a single integrated structure. The support blocks are movable within the housing rather than being separate insert blocks, which reduces assembly steps and enables pre-assembly of the entire device before mounting on the support surface.
3Ease of operation
If the buffer roller is rotatably mounted on an axis with ends retained in housing cavities, then the roller can rotate freely, but the housing structure becomes complex
Solution Approach 1:
The housing structure is segmented into a main housing body and separate movable support blocks. The support blocks contain the buffer roller axis ends and can move independently within the housing, allowing the roller to rotate freely while simplifying the overall housing structure.
Solution Approach 2:
The support blocks are made dynamic and movable within the housing rather than being fixed structural elements. This allows the housing to maintain a simpler overall structure while still providing the necessary support and freedom of rotation for the buffer roller through the movable support mechanism.

AI summary
The device has a cylindrical buffer roller (8) mounted in a housing. The housing comprises a rear end (6) that is fixed on a support (2) by fasteners. The fasteners pass through passage holes (5) on the rear end of the housing. A front end of the housing comprises a passage opening (14) towards in front of a peripheral part (16) of the roller. The device is pre-assembled and mounted in a pre-assembled state on the support. The holes are accessible from the front end of the housing such that the fasteners are introduced into the support through the holes from the front end of the housing. The fasteners are designed as screws.
