Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing utility vehicle designs do not provide sufficient accessibility to the access openings at the rear of the seat, hindering maintenance and operations.
Innovation Solution
The utility vehicle incorporates a detacher mechanism for the seat back, allowing it to be easily attached or detached by up-down movement, and a locker system with forked portions and a lock lever that facilitates secure locking and unlocking, ensuring stable attachment and easy access to the access openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat back is tilted forward to access the opening at the rear of the seat back, then some accessibility is achieved, but the accessibility is still insufficient
Solution Approach 1:
The seat back is divided into detachable segments. The seat back can be completely removed from the vehicle body by detaching it at the locking portions, providing full accessibility to the rear space without requiring complex tilting mechanisms.
Solution Approach 2:
The seat back transitions from a fixed position to a dynamically adjustable state. The locking portions allow the seat back to switch between attached and detached states, enabling complete access to the rear opening when needed.
2Ease of operation
If the seat back is made detachable to improve accessibility, then accessibility is improved, but the attachment stability must be maintained
Solution Approach 1:
The attachment system is segmented into discrete locking portions at the front end of the seat back that engage with corresponding portions on the vehicle body. This segmentation allows for easy detachment while maintaining stable attachment when locked.
Solution Approach 2:
The locking portions are positioned and designed to provide visual feedback on the attachment state, ensuring operators can confirm proper engagement and detachment of the seat back.
