Remote Lock Bolt Mechanism for Parcel Locker Key Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock systems for lockable volumes, such as parcel lockers, often require individual physical keys, leading to management challenges and potential damage, and lack remote operation capabilities, making them inconvenient for secure and accessible access.
Innovation Solution
A remotely operable lock system with a bolt movable between locked and unlocked positions, actuated by a slider and pin mechanism, controlled via a central unit, allowing electronic access without external key components, and incorporating a spring for secure locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical keys are used for locking, then the lock can be operated locally, but key management becomes complex and keys may be damaged or lost
Solution Approach 1:
The patent replaces the traditional mechanical key-based locking system with an electronic locking mechanism. The lock includes an actuator (such as a solenoid or motor) that can be controlled remotely via electronic signals, eliminating the need for physical keys. This substitution resolves the contradiction by maintaining local operation capability through electronic actuation while removing key management complexity and associated risks of key loss or damage.
Solution Approach 2:
The patent implements a digital copy of the key in the form of an electronic code or signal that can be transmitted remotely. Instead of physical keys that can be copied and lost, the system uses digital credentials that can be easily managed, revoked, or updated without physical duplication risks. This allows multiple users to access the lock through electronic means without the physical key management issues.
2Device complexity
If physical keys are used for locking, then the lock structure can be simple, but remote operation capability is lost
Solution Approach 1:
The patent designs the locking mechanism to serve multiple functions: it can be operated locally through electronic controls and remotely through communication networks. The actuator system integrates both local and remote operation capabilities, allowing the same locking mechanism to respond to different types of control signals. This multi-functionality enables the lock to maintain structural simplicity while achieving remote operation capability.
Solution Approach 2:
The patent introduces an electronic intermediary system (such as a controller, sensor, or communication module) that bridges the gap between remote operation and the mechanical locking action. This intermediary receives remote signals and translates them into actuator commands, enabling remote operation without requiring the remote user to directly interact with the mechanical lock structure. The intermediary layer allows simple lock anatomy while achieving complex operation capabilities.
3Reliability
If a bolt mechanism is used for locking, then secure locking can be achieved, but the lock requires precise mechanical alignment and maintenance
Solution Approach 1:
The patent replaces traditional mechanical key-based locking with an electronically controlled actuator system. The actuator (such as a solenoid or motor-driven mechanism) provides secure locking through electronic control rather than mechanical precision. This substitution reduces the need for precise mechanical alignment and maintenance, as the electronic system can compensate for variations in mechanical positioning and the actuator can be easily replaced without requiring specialized alignment procedures.

Function Achieved in This Case
Enables secure, remote operation of lockable volumes, reducing reliance on physical keys, enhancing accessibility, and preventing unauthorized access while maintaining secure locking mechanisms.
Implementation Method 1
a spring disposed around an end of the bolt and in contact with the pin. The spring is biased to urge the bolt into the first locked position

AI summary
Systems, devices, and methods of locking a lockable volume. The lock may comprise a bolt and a slider. The slider moves linearly to move the bolt in position to engage a securement feature. The engagement of the bolt with the securement feature secures the securement feature, thereby locking the door to which the securement feature is attached.
