Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing briefcase locking mechanisms are insufficiently secure due to mechanical weakness, aesthetically unappealing due to external location, and require users to remember combinations or carry keys.
Innovation Solution
A locking mechanism that integrates a blocking element and an actuator with an energy accumulator, allowing the lid of the briefcase to be locked robustly by translating and pivoting, with an unlocking assembly using a solenoid-piston type electromagnet for easy unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional external locks are used, then locking function is provided, but mechanical strength and security are insufficient
Solution Approach 1:
The locking mechanism is merged with the closing mechanism itself. The blocking element is integrated into the movable frame that already performs the closing function, combining two separate functions (closing and locking) into a single integrated system. This resolves the contradiction by providing both locking security and mechanical strength through the unified structure.
Solution Approach 2:
The locking mechanism is nested within the closing mechanism structure. The blocking element is positioned within the movable frame, and the actuator is integrated into the same assembly. This nesting approach allows the locking function to be provided without adding external components, thereby improving both security and mechanical strength while maintaining a compact design.
2Reliability
If locks are placed on the outside of the briefcase, then locking function is provided, but aesthetic appearance is degraded
Solution Approach 1:
The locking function is merged with the closing mechanism, eliminating the need for separate external locks. The blocking element and actuator are integrated into the movable frame that is already part of the closing system, allowing the locking function to be provided without compromising the aesthetic appearance of the briefcase exterior.
3Reliability
If digital combination locks are used, then locking function is provided, but user convenience is reduced due to memory requirements
Solution Approach 1:
The digital combination lock system is replaced with a purely mechanical locking mechanism. The blocking element and actuator provide reliable locking through mechanical means alone, eliminating the need for digital interfaces, combination memory, or electronic components. This improves user convenience while maintaining reliable locking function.
4Reliability
If external locks are used, then locking function is provided, but device complexity increases
Solution Approach 1:
The locking mechanism is merged with the closing mechanism, combining two separate systems into one. The blocking element, actuator, and movable frame work together as an integrated assembly, reducing the overall number of components and simplifying the device structure while providing reliable locking function.
Solution Approach 2:
The movable frame serves multiple functions: it performs the closing action and simultaneously houses the locking mechanism. The blocking element and actuator are designed to work within the existing closing mechanism structure, allowing a single component to fulfill multiple roles and thereby reducing device complexity.

AI summary
The invention relates to a locking mechanism (10) suitable for a device for closing/opening a leaf (60) with respect to a frame (70), by causing the leaf to pivot about a pivot axis upon closing, followed by a translational movement of the leaf (60) that is orthogonal to the pivot axis, from an opening plane to a closing plane. The locking mechanism (10) comprises a locking assembly (12) comprising a blocking element (14) designed to cooperate with a portion of the leaf (60), and an actuator (20) designed to actuate the locking assembly (12) in a locking position wherein the leaf (60) is locked against the frame (70) by the blocking element (14) in the closing plane. The actuator (20) comprises an energy accumulator (22), an actuating rocker (36) rigidly connected to the locking assembly (14), and a connector (26). The connector (26) is designed to connect the energy accumulator (21) to a movable frame (2) of the closing/opening device. The movable frame (2) can be translatably actuated upon the movement of the leaf (60) from the opening plane to the closing plane. The actuator (20) is configured, on the one hand, to store energy in the energy accumulator (22) upon the translational movement of the movable frame (2) when the leaf (60) is moved from the opening plane to the closing plane along a first portion and, on the other hand, to at least partially use the energy stored in the energy accumulator (22) when the leaf (60) is moved from the opening plane to the closing plane along a second portion, for rotatably actuating the actuating rocker (36) in order to bring the locking assembly (12) into the locking position.
