Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional damper apparatuses face challenges in maintaining stable rebound stroke performance and ease of tuning, leading to shocks during vehicle movement, requiring complex manufacturing processes and replacement of internal tubes.
Innovation Solution
A damping force forming member with a body having through-holes and flow passageways is integrated into the damper apparatus, allowing fluid discharge and adjustment of damping force during the rebound stroke, enabling stable performance and easy tuning by varying the design of through-holes and flow passageways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the shape of the inside of the tube is altered to reduce shocks during rebound stroke, then shock reduction is achieved, but manufacturing complexity increases and tuning becomes difficult
Solution Approach 1:
The damping force forming member is divided into multiple functional sections: a body portion with through-holes for fluid discharge, flow passageways for controlled fluid movement, and a contact portion for interaction with the rod. This segmentation allows each section to perform its specific function independently, reducing overall shock impact while maintaining simple manufacturing processes for each component
Solution Approach 2:
The damping force forming member acts as an intermediary component between the rod and the fluid system. It mediates the shock forces by controlling fluid discharge through through-holes and flow passageways, thereby reducing shocks during rebound stroke without requiring complex tube shape modifications
2Adaptability or versatility
If the tube is replaced or remanufactured to vary damper performance, then performance adjustment is possible, but manufacturing complexity and time increase
Solution Approach 1:
The damping force forming member incorporates adjustable parameters such as the number, size, and distribution of through-holes, as well as flow passageway configurations. These dynamic parameters can be varied to adjust damper performance for different vehicle specifications or driving conditions, while each configuration can be manufactured using standard processes
Solution Approach 2:
The damping force forming member serves multiple functions: it forms damping force during rebound stroke, controls fluid discharge, and can be adjusted for different performance requirements. This multi-functionality allows a single component design to accommodate various performance needs without requiring entirely new tube manufacturing
3Stability of the object's composition
If a damping force forming member with through-holes and flow passageways is added, then rebound stroke stability improves, but device complexity increases
Solution Approach 1:
The damping force forming member utilizes the existing fluid system and pressure differentials to automatically regulate damping force during rebound stroke. The through-holes and flow passageways self-adjust based on fluid pressure, providing stable rebound performance without requiring additional control mechanisms or complex external systems

AI summary
A damping force forming member and a damper apparatus including the same are provided. A damping force forming member for forming a damping force is installed in a damper apparatus including a piston, a rod supporting the piston, and an inner tube in which a first chamber and a second chamber are separated by the piston placed therein. The damping force forming member includes: a body supported by the inner tube, that is placed in such a manner that at least part of the inner circumference thereof faces the outer circumference of the rod and forms a damping force when the rod extends; a plurality of through-holes formed at intervals on the body; and a first flow passageway placed between the body and the inner tube, 10 for guiding the movement of a fluid in the first chamber that has passed through the plurality of through-holes.
