Locker Device Door Locking in Standby Mode to Prevent Improper Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage apparatuses allow doors of storage units to remain unlocked when no items are stored, leading to improper use such as item placement without payment or disposal of trash.
Innovation Solution
A storage apparatus with a locking device that maintains the door in a locked state during standby mode and allows controlled switching operations based on user input, using solenoids and detecting mechanisms to manage door states and user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door of a storage unit is left unlocked while no item is stored, then the storage unit is easily accessible for legitimate use, but improper use occurs such as items being placed without payment or trash being discarded
Solution Approach 1:
The door is locked in advance before any storage operation occurs. The locking device maintains the locked state as a preliminary condition, and only after authentication and payment through the operating unit is the door unlocked, preventing improper use before legitimate access is established
Solution Approach 2:
The locking device acts as an intermediary between the door and the user. It controls door access by requiring authentication through the operating unit, serving as a mediator that prevents direct unauthorized access while allowing legitimate use through the controlled unlocking mechanism
2Object-affected harmful factors
If a locking device is added to prevent improper use, then unauthorized access is reduced, but the device complexity increases with additional components like drive means and detecting means
Solution Approach 1:
The locking device is designed to perform multiple functions: it locks the door in the locked state, unlocks the door when authentication is received, and can be controlled through the operating unit. This multi-functionality reduces the need for separate components and simplifies the overall system architecture
Solution Approach 2:
The locking device is integrated with the operating unit and control system. The drive means and detecting means are combined into a unified locking mechanism that communicates with the controller, merging multiple functional elements into a coordinated system that reduces overall complexity
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
The solution effectively prevents improper use of storage units by ensuring doors remain locked when not in use, reducing unauthorized access and misuse.
Implementation Method 1
the locking device includes restricting means that implements restriction of the first switching operation in the locked state, first drive means that drives the restricting means to implement or release the restriction
Implementation Method 2
second drive means for performing the first switching operation
Implementation Method 3
first detecting means that detects an open/closed state of the door
Implementation Method 4
second detecting means that detects that the second switching operation is performed
