Mineproof Seat Notch Damping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mine-proof seat devices fail to effectively reduce impulse transmission from the roof to occupants during mine impacts, often requiring additional installation space for deformation elements.
Innovation Solution
The seat device incorporates a notch system that allows the seat to move downwards with the roof during an impact and then release a defined downward path upon roof reversal, utilizing integrated notches for damping without the need for additional deformation elements, and allows for adjustable height and vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an energy-distorting element is integrated into the seat frame to absorb acceleration forces, then the impulse transmission to occupants is reduced, but additional installation space is required
Solution Approach 1:
The patent combines the energy-absorbing function with the existing seat frame structure by integrating notches directly into the seat frame members. This merging eliminates the need for separate deformation elements while maintaining the impulse absorption capability, thereby resolving the contradiction between reducing impulse transmission and minimizing installation space
Solution Approach 2:
The patent extracts the energy-absorbing function from a separate component and integrates it directly into the seat frame structure through notches. This extraction and integration approach eliminates the need for additional installation space while preserving the harmful factor reduction capability
2Strength
If the seat is rigidly connected to the roof structure, then structural strength is maintained, but impulse forces are transmitted directly to occupants during impact
Solution Approach 1:
The patent transforms the rigid connection into a dynamic system by incorporating notches that allow controlled movement and deformation during impact. The seat frame can dynamically absorb energy through the notches while maintaining structural integrity, resolving the contradiction between strength and impulse force transmission
Solution Approach 2:
The notches are pre-designed into the seat frame structure to provide energy absorption capability before impact occurs. This beforehand cushioning allows the structure to dissipate impulse forces through controlled deformation, maintaining strength while reducing harmful force transmission to occupants
3Object-affected harmful factors
If deformation elements are added to the seat frame, then damping effect is improved, but device complexity increases
Solution Approach 1:
The patent merges the damping function with the existing seat frame structure by integrating notches directly into the frame members. This eliminates the need for separate deformation elements, maintaining the damping effect while reducing device complexity
Solution Approach 2:
The seat frame structure serves its own damping function through the integrated notches, eliminating the need for additional specialized components. The structure is self-sufficient in providing both structural support and energy absorption, reducing overall device complexity

Function Achieved in This Case
This solution minimizes stress on occupants by providing a damping effect during impacts, reducing the transmission of impulse forces and eliminating the need for additional installation space for deformation elements, while maintaining height adjustment and vertical movement functionality.
Implementation Method 1
A third tube (7) is now slipped over each additional tube (4) ( 2 ), to which the seat 1 is now attached (no longer to the seat carriage 4, as in 1 ). This tube 7 includes the catch 8 which is prestressed. The bias can be done via a spring 9 etc.

AI summary
The invention relates to a mine-safe seat device (10) having tubes (2) for connecting to a vehicle roof (3) or to a vehicle floor. An additional tube (4) is placed over the seat device (10) as a seat slide, which has notches for a detent (8) on the outside of said tube. An additional tube (7), to which the actual seat (1) is fastened, is placed over said seat slide (4). The detent (8) is integrated on the tube (7) placed over the seat slide (4). The detent is preloaded so that when a force that cancels out the preload is reached, the detent (8) slides further downward along the notches of the seat slide (4) and releases additional travel.
