Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex electronics systems, especially those with numerous electrical and mechanical connections, existing mechanisms require significant force to insert or remove replaceable units, potentially causing damage and are not easily executed.
Innovation Solution
A module injection mechanism comprising a lever, a screw affixed to the chassis via a sliding bushing, and a lower lever portion with pivot holes, allowing mechanical force to be transferred for easy mounting and dismounting of modules without causing harm, using a knurled screw and a sliding bushing to facilitate the insertion and ejection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insertion mechanisms are used to mount replaceable units with numerous electrical and mechanical connections, then the module can be securely mounted to the chassis, but a considerable force is required that may cause harm or damage to the module
Solution Approach 1:
The patent introduces a lever arm as an intermediary mechanical element between the user's manual force and the module insertion process. The lever arm pivots about an axis and transfers force through a bolt mechanism, acting as a mediator that reduces the direct force requirement on the module while achieving secure mounting. This resolves the contradiction by allowing secure mounting without requiring considerable direct force that could damage the module.
2Reliability
If conventional insertion mechanisms are used to mount replaceable units, then the module can be securely mounted to the chassis, but a considerable force is required making the process difficult to execute
Solution Approach 1:
The patent employs a dynamic lever arm mechanism that pivots about an axis during the insertion process. The lever arm transitions from a retracted position to an extended position, dynamically changing the mechanical advantage throughout the insertion stroke. This dynamic mechanism allows a user to easily operate the system by simply moving the lever arm, while still achieving secure mounting of the module to the chassis.
3Ease of operation
If a lever mechanism with pivot holes is used to reduce insertion force, then the ease of operation is improved, but the device complexity increases due to additional components
Solution Approach 1:
The lever arm serves multiple functions within a single component: it acts as a force amplifier, a positioning guide for the module, and a mechanical connector between the user interface and the mounting mechanism. The bolt integrated into the lever arm also serves dual purposes as both a structural element and a pivot point. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while maintaining improved ease of operation.

Function Achieved in This Case
Enables the easy injection of replaceable units onto a chassis without causing damage, reducing the need for high forces and simplifying the insertion and extraction processes, maintaining existing system compatibility.
Implementation Method 1
the injection assembly is capable to transfer a mechanical force applied to the lever grabbing portion to the sliding bushing
Implementation Method 2
the pivot screw that slides within the oval pivot hole causes a sliding at the same time of the sliding bushing along the axis of the screw
