Parking Lock Release Access Through Vehicle Undercover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in accessing the operation unit for manually releasing the locked state of a parking lock mechanism, often requiring cumbersome methods like jacking up the vehicle or removing components.
Innovation Solution
A vehicle design featuring a parking lock unit with an actuator that switches between locked and unlocked states, an operation unit for manual operation, and an under cover with a through hole to expose the operation unit, allowing easier manual release of the locked state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operation unit is positioned in a location that ensures proper mechanical linkage with the parking lock mechanism, then the reliability of the locking system is improved, but the ease of operation deteriorates because users cannot easily access the operation unit
Solution Approach 1:
The operation unit is made accessible from a different spatial dimension by providing a through-hole in the under cover, allowing users to access the operation unit from below the vehicle rather than from the side or top where it would be mechanically linked but inaccessible
2Stability of the object's composition
If the operation unit is positioned deep within the vehicle structure to ensure proper mechanical linkage, then the structural integrity is improved, but the ease of operation deteriorates as users must jack up the vehicle or remove components to access it
Solution Approach 1:
The under cover is segmented with a through-hole that allows access to the operation unit while maintaining the overall structural integrity of the vehicle body, separating the access path from the structural framework
Solution Approach 2:
The operation unit is accessed from the bottom dimension through the under cover rather than from the side or top, allowing users to reach it without compromising structural integrity or requiring vehicle jacking

AI summary
The vehicle includes a SBW actuator capable of switching between a locked state in which the drive wheels of the vehicle are restrained from rotating and an unlocked state in which the rotation of the drive wheels is not restrained by the actuator, a parking lock releasing operation unit for switching the locked state of SBW actuator to an unlocked state by manual operation, and an undercover covering a lower portion of the parking lock releasing operation unit, and the undercover is provided with a through hole, and the parking lock releasing operation unit is exposed downward from the through hole.
