Solution Overview
Problem
Current package locker systems have inefficiencies due to fixed sizes, leading to underutilization of certain locker sizes and difficulties in changing the mix of sizes post-installation, as well as issues with damaged locker doors, which can result in theft and inefficient use of space.
Innovation Solution
A field-configurable locker system with a central control unit that adjusts the ratio of locker sizes based on usage data, allowing for dynamic changes in locker sizes and easy replacement of doors, ensuring optimal usage and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed array of locker sizes is installed, then the initial configuration is simple and quick to deploy, but the system cannot adapt to changing package size demands and results in underutilization of certain locker sizes
Solution Approach 1:
The locker system is divided into modular components where individual locker doors can be independently removed and replaced. Each door is a separate module that can be detached from the locker body, allowing the configuration to be segmented and reconfigured without affecting the entire system. This enables adaptive changes while maintaining overall system simplicity.
Solution Approach 2:
The locker array transitions from a static fixed configuration to a dynamic reconfigurable system. The ability to easily remove and replace doors allows the system to adapt its configuration over time based on changing demands. The modular door design enables the system to evolve from a fixed state to a dynamically adjustable state without complex reconstruction.
2Reliability
If locker doors are made secure and difficult to remove, then security is improved, but damaged doors cannot be easily replaced and maintenance becomes complex
Solution Approach 1:
The door assembly is segmented into separable components with standardized interfaces. The door can be detached from the locker body through a simple removal process that does not compromise security during normal operation. When damage occurs, only the damaged door module needs to be replaced rather than the entire locker, simplifying maintenance while maintaining security through the standardized secure interface.
Solution Approach 2:
The system is designed to allow easy discarding of damaged doors and replacement with new or refurbished units. The standardized interface enables quick removal of damaged components and installation of replacements, facilitating rapid maintenance cycles. Security features are recovered through the standardized secure interface that ensures proper installation of replacement doors.
3Productivity
If the locker array is designed with fixed sizes, then manufacturing and installation are simplified, but the system cannot optimize space utilization based on actual usage patterns
Solution Approach 1:
The locker system uses standardized modular components that can be manufactured using simple, repeatable processes. The segmentation into uniform door and body modules allows for efficient manufacturing and straightforward installation. This modular approach enables the system to achieve complex reconfigurability while maintaining manufacturing simplicity through standardization.
Solution Approach 2:
The system optimizes space utilization by changing the configuration parameters of the locker array through simple door replacements rather than manufacturing new lockers. By adjusting which door sizes are installed in which positions, the system can adapt to changing usage patterns and optimize space utilization without requiring complex manufacturing processes or complete system reconstruction.

AI summary
A system for securely delivering packages of at least two different sizes by a sender to a receiver is disclosed comprising, installing an array of lockers of at least two different sizes with the number of lockers of each size based on a predetermined installed ratio, a central control unit for controlling the locking portions on the array of lockers having a locker optimization unit adapted to use data collected on the frequency of use of each size of lockers to recommend a ratio of lockers of each size to maximize usage of lockers of appropriate size in the array, wherein if the recommended ratio is different from the installed ratio, changing the sizes of selected lockers after installation of the array to better match the recommended ratio by replacing doors without removing hinge pins and moving and re-fastening the top and bottom walls of the lockers.
