Movable Latch Mechanism for Tool-Free Keyboard Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers have complex and labor-intensive procedures for assembling and disassembling the keyboard, which requires additional tools and can lead to component damage due to inadequate force application.
Innovation Solution
An electronic device design featuring a movable latch that moves between two receiving areas, allowing the detachable member to be assembled or disassembled without additional tools, using an elastic arm and engaging portions for secure locking and easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a movable latch is used to assemble or disassemble the keyboard, then the keyboard can be detached from the case, but the user needs to push against the movable latch with one hand while holding a tool with the other hand, making the procedure difficult and time-consuming
Solution Approach 1:
The detachable member is designed to automatically move the movable latch between receiving areas during its own assembly and disassembly process. When the detachable member is inserted or removed, it directly actuates the movable latch to switch between locked and unlocked states, eliminating the need for separate manual operations with tools.
Solution Approach 2:
The assembly and disassembly functions are merged into a single integrated mechanism where the detachable member itself serves as the actuating element. The same component that is being assembled or disassembled also performs the locking and unlocking actions, combining multiple functions into one unified operation.
2Ease of operation
If a movable latch is used to assemble or disassemble the keyboard, then the keyboard can be detached from the case, but the user may inadequately apply force during the procedures, resulting in damages to relevant components
Solution Approach 1:
The detachable member automatically actuates the movable latch during its own assembly and disassembly, eliminating manual force application that could be inadequate or excessive. The system self-regulates the force and motion required for safe operation.
Solution Approach 2:
The movable latch serves as an intermediary mechanism between the detachable member and the case. It mediates the interaction by providing a controlled, progressive motion that distributes force evenly, preventing sudden impacts or inadequate force application that could damage components.
3Stability of the object's composition
If the keyboard is locked to the case by a screw, then the keyboard is securely fixed, but the processes of locking and disassembling are complicated and labor-consuming
Solution Approach 1:
The attachment mechanism is segmented into distinct functional areas: a first receiving area for securing the detachable member and a second receiving area for locking the movable latch to the plate. This segmentation allows independent optimization of each locking function, simplifying the overall procedure while maintaining stability.
Solution Approach 2:
The fixed screw connection is replaced with a dynamic movable latch that can transition between positions. The latch moves between the first receiving area (where it locks the detachable member) and the second receiving area (where it locks to the plate), providing secure attachment during use while enabling easy disassembly when needed.
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
Facilitates convenient assembly and disassembly of the detachable member, reducing the risk of component damage and simplifying maintenance processes by eliminating the need for additional tools.
Implementation Method 1
The movable latch has an elastic arm, a turning portion, and a first engaging portion. The turning portion is suitable for receiving a force to drive the elastic arm, such that the first engaging portion moves back and forth between the first receiving area and the second receiving area.

AI summary
An electronic device includes a case, a plate, and a detachable member. The case has a first receiving area, a second receiving area, and a movable latch. The first receiving area is adjacent to the second receiving area. The movable latch moves back and forth between the first receiving area and the second receiving area. The detachable member is assembled to the first receiving area. The plate is assembled to the second receiving area. When the movable latch is located in the first receiving area, the movable latch locks the detachable member to the case. When the movable latch moves to the second receiving area, the movable latch is locked to the plate.
