Secure article presentation device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article presentation devices for valuable items like watches are either complex, insecure, or unsightly, and often require all items to be locked or released simultaneously, which can compromise security and user experience.
Innovation Solution
A device featuring a base with slots and movable catches, each actuated by a distinct drive mechanism, allowing for secure and independent presentation of articles, with a compact design and attractive appearance, enabling easy extraction of items without affecting security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If all watches are locked or released simultaneously using a single drive mechanism, then the device structure is simplified, but security is compromised because extracting one watch affects the security of other watches
Solution Approach 1:
The single drive mechanism is segmented into multiple independent drive mechanisms, with each drive mechanism controlling a specific catch associated with a particular slot. This segmentation allows independent control of each watch's locking state, resolving the contradiction by enabling simplified individual operation while maintaining security for other watches when one is extracted.
2Ease of manufacture
If multiple catches are controlled by a single drive mechanism, then the device is easier to manufacture, but the ease of operation is reduced because all catches must be actuated together
Solution Approach 1:
The drive mechanism is divided into multiple independent units, each responsible for actuating a specific catch. This segmentation improves ease of operation by allowing selective actuation of individual catches while maintaining manufacturing simplicity through modular design where each unit can be produced and assembled independently.
Solution Approach 2:
Each drive mechanism unit is designed with universal functionality to actuate its associated catch, allowing the same design to be replicated across multiple slots. This multi-functionality approach maintains ease of manufacture through standardization while providing operational flexibility for each individual catch.
3Reliability
If the catch occupies significant space to ensure reliable locking, then the locking reliability is improved, but the device becomes less compact and more difficult to integrate
Solution Approach 1:
The catch is designed to nest within the slot structure when not in use, and the drive mechanism is integrated into the base in a space-efficient manner. This nesting approach allows the catch to occupy minimal space while maintaining reliable locking engagement when activated, resolving the contradiction between locking reliability and space occupation.
