Mechanical Lock with Manual Code Selection for Parcel Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current modular parcel delivery and reception locker systems lack a mechanism to allow discriminated, manual operation with multiple codes, where only one code can open the lock at a specific time and require electronic or computerized systems for authorization.
Innovation Solution
A redesign of the mechanical lock with a user selection device that allows manual code change and locking, using combination plates with ascending and descending movement, and continuous motion restriction elements to set specific positions, enabling manual closure and indication of the authorized user without electronic systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electromagnetic or computerized systems are used to enable discriminated opening with multiple codes, then the ability to authorize multiple users is improved, but the device complexity and dependency on electronic systems increases
Solution Approach 1:
The patent replaces electromagnetic or computerized authorization systems with a purely mechanical solution. The lock uses a combination of a fixed code mechanism and a movable plate system with multiple code positions. The selector knob mechanically adjusts the position of code plates to match different user codes, eliminating the need for electronics while maintaining multi-user authorization capability.
Solution Approach 2:
The code authorization mechanism is segmented into multiple independent code plates, each representing a different user code. These plates can be independently positioned by rotating the selector knob, allowing the lock to mechanically configure different code combinations for different users without requiring electronic reprogramming.
2Adaptability or versatility
If a single mechanical code is used for each compartment, then the lock structure is simple, but the ability to serve multiple users with exclusive access is reduced
Solution Approach 1:
The lock mechanism incorporates dynamic elements where code plates can be moved to different positions using a selector knob. This allows the same physical lock to dynamically reconfigure its code combination to serve different users, transforming a static single-code lock into a dynamic multi-code system without requiring multiple separate locks.
Solution Approach 2:
The lock mechanism is designed to perform multiple functions: it can be configured to authorize different user codes sequentially, serving as a universal access control system for multiple users. The same lock body and deadbolt mechanism serve all users, with only the code plates being reconfigured, achieving multi-functionality without proportional increase in overall system complexity.
3Ease of operation
If electromagnetic locks with multiple authorized codes are used, then discriminated opening for different users is enabled, but the loss of time for system setup and electronic dependency increases
Solution Approach 1:
The code plates are pre-configured with different user codes during manufacturing or initial setup. When a new user needs access, the selector knob is simply rotated to bring the appropriate pre-configured code plate into position, eliminating the need for time-consuming electronic programming or code generation during actual use.

AI summary
The invention relates to a mechanical lock (37) for a plurality of keys (26) that can be authorized with a different code (39), with discriminated opening using a selection device (1) that can be activated manually from outside, a signaling element for displaying the selected code (2) (3), a manual closure (4) and locking (19) (15) mechanism, integrated with a modular set of lockers (FIG. 15) for delivery home and collection of parcels. The invention allows the use of a limited number of modular lockers for a larger set of users without requiring computer applications, electricity or an internet connection during the delivery, which is especially for common areas of communities of residents, building lobbies, housing estates, shared spaces or offices.
