Lid Lock Controller Key Proximity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lid lock devices for vehicles are inconvenient as they require users to unlock the vehicle door before unlocking the fuel lid or necessitate proximity to a feet detection sensor, and may unintentionally unlock the lid when the user is near, lacking user-intended operation and convenience.
Innovation Solution
A lid lock controller with a detection unit, key check unit, and unlocking unit that allows unlocking of the lid based on electronic key proximity via wireless communication, enabling unlocking even without the key present if the vehicle door is already unlocked, using a communication system for smart verification and actuator-controlled lid lock pin movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid lock device requires electronic key proximity verification for unlocking, then security is improved, but user convenience deteriorates when the key is not available
Solution Approach 1:
The lid lock device dynamically adjusts its unlocking conditions based on the vehicle door lock state. When the door is unlocked, the lid lock accepts alternative unlocking methods (door unlock signal) without requiring electronic key proximity, making the system flexible and adaptive to different usage scenarios
Solution Approach 2:
The system checks the vehicle door lock state as a preliminary condition before requiring electronic key proximity verification. If the door is already unlocked, the lid lock bypasses the key proximity requirement, using the door unlock state as a pre-verified security condition
2Extent of automation
If the lid lock device uses feet detection sensor for unlocking, then automatic unlocking is improved, but false unlocking and security risks worsen when user is in vicinity
Solution Approach 1:
The lid lock device incorporates feedback from the vehicle door lock state to control the unlocking behavior. The control unit continuously monitors whether the door is locked or unlocked and uses this feedback to determine whether to enable alternative unlocking methods, preventing false unlocking by ensuring the door state is properly verified first
Solution Approach 2:
The vehicle door lock state serves as an intermediary condition between the feet detection sensor and the lid lock unlocking action. Instead of directly linking sensor detection to lid unlocking, the system uses the door lock state as a mediating verification layer to prevent unauthorized or false unlocking
3Reliability
If the lid lock device requires vehicle door unlocking before lid unlocking, then security is improved, but operational flexibility deteriorates
Solution Approach 1:
The unlocking requirements dynamically change based on the vehicle door lock state. When the door is unlocked, the lid lock becomes more flexible by accepting door unlock signals as a valid unlocking method without requiring electronic key proximity, adapting to the current security context
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user convenience by allowing intended lid unlocking without the electronic key's proximity, reduces unnecessary security measures, and improves power efficiency by only activating the actuator during unlocking.
Implementation Method 1
a key check unit checks whether or not an electronic key is located in the vicinity of the vehicle through wireless communication between the vehicle and the electronic key
Data Source
AI summary
A lid lock controller includes a lid lock unit operable in a lock state, which keeps the lid closed, and an unlock state, which allows for the lid to open. A detection unit detects an unlocking operation performed on the lid lock unit. A key check unit checks whether or not an electronic key is located in the vicinity of the vehicle through wireless communication between the vehicle and the electronic key when the unlock operation is detected. An unlocking unit switches the lid lock unit to the unlock state when the electronic key is located in the vicinity of the vehicle. The unlocking unit switches the lid lock unit to the unlock state even when the electronic key is not located in the vicinity of the vehicle as long as a further lid unlock condition is satisfied.
