Fuel Lid Pushrod Locking Mechanism Against Unintended Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing forward/backward movement device is vulnerable to being locked unintentionally when the pushrod is pushed backward, either by mischief or other means, while the fuel lid is open, leading to unintended operation.
Innovation Solution
A forward/backward movement device is designed with a biasing member that allows the forward/backward member to move forward by a biasing force, and a restricting member that prevents the movement from being locked by restricting the moving member's position when the lid is open, ensuring the forward/backward member can move freely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is provided to restrict the forward/backward movement of the pushrod, then the fuel lid can be prevented from opening when closed, but the pushrod can be unintentionally locked when the fuel lid is open due to mischief or other factors
Solution Approach 1:
The restricting member is configured to dynamically change its position based on the fuel lid state. When the fuel lid is open, the restricting member moves to a position that blocks the moving member, preventing it from restricting the forward/backward member. When the fuel lid is closed, the restricting member moves away, allowing the locking mechanism to function normally. This dynamic adjustment eliminates the harmful effect of unintentional locking while maintaining the intended locking function.
Solution Approach 2:
The restricting member acts as an intermediary between the moving member and the forward/backward member. It selectively controls whether the moving member can restrict the forward/backward member based on the fuel lid state. This intermediary mechanism prevents direct harmful interaction between the moving member and forward/backward member when the fuel lid is open, while allowing normal operation when closed.
2Ease of operation
If the moving member is allowed to move freely between positions, then the forward/backward member can be locked when needed, but the forward/backward member becomes vulnerable to unintentional locking when the lid is open
Solution Approach 1:
The restricting member dynamically adjusts its position based on the fuel lid state. When the fuel lid is open, it moves to block the moving member's path, preventing unintentional locking. When the fuel lid is closed, it moves away to allow the moving member to function freely for intended locking operations. This dynamic behavior resolves the contradiction between operational freedom and protection against mischief.
Solution Approach 2:
The restricting member performs preliminary anti-action by positioning itself to block the moving member before any unintentional locking can occur. When the fuel lid is open, the restricting member proactively prevents the moving member from reaching the position where it could lock the forward/backward member, thus preventing harmful effects before they can manifest.

AI summary
A forward/backward movement device includes: a case; a forward/backward member; a biasing member that biases the forward/backward member; a moving member that is housed in the case and moves between a first position where the forward/backward member is capable of moving forward by a biasing force generated by the biasing member and a second position where the forward movement of the forward/backward member is stopped; and a restricting member that restricts a movement of the moving member by moving to a position for restricting the moving member while a lid is open, in which the restricting member restricts a movement of the moving member from the first position to the second position in a case where the forward/backward member moves backward while the lid is open.
