Vehicle Lid Lock Control for Selective Door Interlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing lid systems, the locked and unlocked states of the lid locking device are interlocked with the door locking device, requiring the door locking device to be unlocked to unlock the lid, which is undesirable when the vehicle is supplied with energy.
Innovation Solution
A lid system with a user-operable switch that controls the interlocking of the lid locking device's states with the door locking device's states, allowing the lid to be unlocked without unlocking the door when the switch is turned off, and interlocking them when turned on.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid locking device is interlocked with the door locking device, then the security and coordination of the vehicle locking system is improved, but the flexibility to open the lid independently is worsened
Solution Approach 1:
The system dynamically changes the interlocking relationship between the lid locking device and door locking device based on the switch state. When the switch is on, interlocking is enabled for enhanced security; when off, interlocking is disabled to allow independent lid operation. This dynamic reconfiguration resolves the contradiction by adapting the system's locking behavior to user needs.
Solution Approach 2:
The lid locking device serves multiple functions: it can operate in interlocked mode with the door locking device for coordinated security, or in independent mode for flexible standalone operation. The switch enables the system to universalize the locking mechanism to handle both security-oriented and convenience-oriented scenarios.
2Extent of automation
If the lid locking device is interlocked with the door locking device, then the coordinated control of vehicle components is improved, but the operational independence of the lid is worsened
Solution Approach 1:
The interlocking control dynamically adjusts based on switch state. In automated interlocked mode, the lid locking device coordinates with the door locking device for unified vehicle security management. In manual independent mode, the lid can be operated separately without affecting door locks, providing ease of operation when needed.
Solution Approach 2:
The switch acts as an intermediary element that mediates between the automated interlocked control system and the manual independent operation mode. By switching the interlocking state, it allows the system to transition between high-level automated coordination and simple independent operation.
3Reliability
If the door locking device must be unlocked to unlock the lid locking device, then the security protocol is improved, but the time and steps required to access the lid are worsened
Solution Approach 1:
The security protocol dynamically adapts based on switch state. When the switch is on, the system enforces a strict security protocol requiring door unlock before lid unlock, ensuring high security. When the switch is off, the system relaxes the protocol to allow direct lid unlocking, reducing time and steps while maintaining acceptable security.
Solution Approach 2:
The system changes the operational parameters of the lid locking device based on switch state. In interlocked mode, the unlock condition parameter requires door locking device state change first. In non-interlocked mode, the unlock condition parameter allows direct operation, changing the system's security threshold to match user needs.

AI summary
A lid system includes: a lid for a vehicle, the lid being configured to be opened when the vehicle is supplied with energy; a lid locking device for the lid; a control device configured to control the lid locking device; and a switch operable by a user. When the switch is turned on, the control device interlocks a locked state and an unlocked state of the lid locking device with a locked state and an unlocked state of a door locking device for a door of the vehicle. When the switch is turned off, the control device does not interlock the locked state and the unlocked state of the lid locking device with the locked state and the unlocked state of the door locking device.
