Computer Case Mounting Structure with Slide and Lever Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer case mounting structures are cumbersome and time-consuming to open and close, often requiring screws that wear out quickly, and alternative designs with hooks can be difficult to manage due to tight fastening or accidental disconnection.
Innovation Solution
A case member mounting structure using a first and second case member, a slide, a spring member, and an operation lever, where the slide is moved by the operation lever to engage or disengage retaining members without screws, allowing easy locking and unlocking with minimal effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fasten case body and top cover, then secure connection is achieved, but mounting and dismounting becomes complicated and time-consuming
Solution Approach 1:
The fastening mechanism is divided into separate functional components: retaining members with hooked portions for connection, slides for controlled movement, and operation levers for actuation. This segmentation allows each component to perform its specific function efficiently, enabling secure fastening while simplifying the mounting and dismounting operations.
Solution Approach 2:
The fastening system transitions from a static screw connection to a dynamic mechanism where slides can move between positions and operation levers can be rotated. This dynamic design allows the connection to be securely fastened during normal use but easily opened when needed, resolving the contradiction between connection strength and operational ease.
2Strength
If screws are used for fastening, then case members are securely connected, but screw threads wear quickly with use
Solution Approach 1:
The invention extracts and eliminates the screw component entirely from the fastening system. By replacing screws with a mechanism using retaining members, slides, and operation levers, the design removes the source of the durability problem (screw thread wear) while maintaining secure connection capability through alternative means.
Solution Approach 2:
The operation lever and slide are designed as replaceable components that can be easily replaced if worn or damaged, rather than permanent screw threads. This approach accepts that these components may wear but allows for easy replacement without the complexity of screw thread restoration or replacement.
3Ease of operation
If hooks and hook holes are used for connection, then fastening is simplified, but hooks may be fastened too tight requiring much effort to pull apart
Solution Approach 1:
The operation lever provides a dynamic mechanism that controls the engagement and disengagement of the retaining members. When the lever is in the engaged position, the hooks are firmly connected. When rotated to the disengaged position, the slide moves to release the hooks, reducing the force needed to separate the case members.
Solution Approach 2:
The slide acts as an intermediary component between the operation lever and the retaining members. It translates the rotational motion of the operation lever into linear motion that controls the engagement and disengagement of the hooks, providing controlled force application during both fastening and separation operations.
4Ease of operation
If hooks are not tightly hooked, then easy separation is achieved, but top cover may be forced away accidentally
Solution Approach 1:
The system provides two distinct dynamic states: an engaged state where the retaining members are firmly hooked for stable connection during normal use, and a disengaged state where the slide moves to release the hooks for easy separation when needed. The operation lever controls transitions between these states, ensuring both connection stability and separation ease.
Solution Approach 2:
The spring member provides feedback force that maintains the slide in the engaged position during normal use, ensuring tight hooking for stability. When the operation lever is actuated, the spring releases and allows the slide to move to the disengaged position, enabling easy separation. This feedback mechanism ensures the connection is stable during use but easily separable when intended.
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
Enables secure locking and easy unlocking of case members without screws, reducing effort and wear on components, while maintaining structural integrity and ease of use.
Implementation Method 1
The spring member is connected between the first case member and the slide and imparts a pull force to the slide in a second direction
Implementation Method 2
When the operation lever is rotated to a second position, the operation lever pushes the slide to move in the first direction

AI summary
A computer with a case member mounting structure includes a first case member, a second case member, a slide, a spring member, and an operation lever. The first case member has at least one opening. The second case member includes at least one first retaining member. The slide is movably supported on the first case member. The push portion of the first retaining member is inserted into the opening for pushing the slide to move in a first direction to a first position so that the hooked portion of the first retaining member is engaged with the opening. The operation lever is pivoted to the first case member. When the operation lever is rotated to a second position, the operation lever pushes the slide to move in the first direction, so as to disengage the hooked portion from the opening.
