Laundry Cabinet Top-Plate Locking for Payment Unit Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial laundry machines face issues with the theft of payment units due to inadequate securing of the cabinet, where even enhanced securing of the payment unit does not prevent the entire cabinet from being removed along with it.
Innovation Solution
A laundry machine design featuring a locking device integrated into the top plate, which includes a key-operated mechanism with coupling surfaces and locking slots, and fixing holes and pieces to secure the top plate to the cabinet, preventing unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the payment unit is firmly secured to the cabinet, then the payment unit cannot be stolen, but the entire cabinet can still be removed together with the payment unit if the cabinet securing is poor
Solution Approach 1:
The locking system is segmented into multiple independent components: locking protrusions on the top plate, corresponding locking grooves on the cabinet, and a separate locking device with key box. This segmentation allows the payment unit to be firmly secured through multiple distributed locking points rather than a single complex mechanism, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The locking device is nested within the cabinet structure, with the key box integrated into the cabinet body and the locking mechanism embedded between the top plate and cabinet. This nesting approach secures the payment unit through a compact, multi-layered structure that provides strong securing without excessive external complexity.
2Reliability
If a locking device with key box is integrated into the cabinet structure, then the cabinet remains secure and prevents theft, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to be self-servicing through the key box system. The key box stores备用 keys and allows authorized personnel to lock or unlock the cabinet independently without requiring external assistance or complex mechanical key systems. This simplifies the overall device complexity while maintaining high reliability through automated key management.
3Strength
If multiple locking slots and fixing pieces are used to secure the top plate, then the cabinet structure becomes more secure, but the manufacturing complexity increases
Solution Approach 1:
The locking protrusions, locking grooves, and fixing pieces are pre-positioned and pre-aligned during the design and manufacturing phase. The top plate and cabinet are designed with predetermined locking slot positions that automatically align during assembly, eliminating the need for complex real-time adjustment procedures and simplifying the manufacturing process while maintaining strong structural integrity.

AI summary
The present invention relates to a laundry washing apparatus and particularly to a laundry washing apparatus comprising a base that forms a lower face, front/rear plates that form front and rear directions, side plates that form both sides, and a top plate that forms an upper part, wherein the top plate is further furnished with a locking device that controls the locking state of the top plate by means of an external key insertion operation, so that theft of a payment apparatus installed on the top plate can be effectively prevented.
