Work Vehicle Seat Layout to Prevent Shoulder Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multipurpose work vehicles often cause discomfort due to the proximity of occupants' shoulders or arms when seated next to each other, and existing configurations do not effectively address this issue without increasing vehicle length or space.
Innovation Solution
The driver's seat is positioned centrally with occupant seats offset rearwardly, allowing for comfortable seating without shoulder or arm contact, and incorporating a roll-over protective structure with grips for easy entry and exit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the driver's seat and occupant's seat are arranged side by side in the lateral direction, then the vehicle can carry multiple occupants, but the occupants come into contact with each other by the shoulder or arm, causing discomfort
Solution Approach 1:
The patent transitions from a purely lateral arrangement to a combination of lateral and longitudinal positioning. The occupant's seat is placed laterally adjacent to the driver's seat but offset in the longitudinal direction (front or rear), creating a two-dimensional seating layout that prevents shoulder/arm contact while maintaining compact vehicle dimensions.
2Ease of operation
If the driver's seat is positioned centrally with occupant's seat offset rearwardly, then occupants do not come into contact with each other, but the vehicle length increases
Solution Approach 1:
The patent applies local quality by making the offset distance between the driver's seat and occupant's seat adjustable rather than fixed. This allows the longitudinal positioning to be optimized for different vehicle lengths and occupancy scenarios, providing comfort without unnecessarily increasing vehicle length.
Solution Approach 2:
The patent introduces adjustability in the longitudinal positioning of the occupant's seat relative to the driver's seat. This dynamic configuration allows the seating arrangement to be adapted to different vehicle sizes and usage requirements, preventing contact while minimizing length increase.
3Length of moving object
If the distance between driver's seat and front end of vehicle body is small, then the vehicle remains compact, but there is insufficient space to arrange driver's seat and occupant's seat without contact
Solution Approach 1:
The patent resolves the space constraint by utilizing both lateral and longitudinal dimensions for seat arrangement. The occupant's seat is positioned laterally adjacent to the driver's seat with a longitudinal offset, effectively using the available three-dimensional space within the compact vehicle body to prevent contact without increasing overall length.
