Spring Arm Feedback Mechanism for Electronics Module Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators lack tactile feedback when detaching electronics modules from a base, making it difficult to confirm electrical disconnection and complete separation, which is crucial for diagnostic purposes.
Innovation Solution
A feedback system using a spring arm with a follower and cams on the base and module walls, providing distinct tactile feedback through cam displacement as the module attaches or detaches, indicating electrical connection or disconnection and separation state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid guide wall is used to assist in attaching or detaching modules, then the structural stability and alignment are improved, but the operator lacks tactile feedback on the electrical connection state
Solution Approach 1:
The patent implements a feedback mechanism by incorporating a spring arm with a follower that contacts cams on the module. As the module moves along the guide wall during attachment or detachment, the follower rides over the cams, causing the spring arm to deflect and provide tactile feedback to the operator. This feedback system communicates the electrical connection state through distinct tactile cues, resolving the contradiction by adding feedback functionality while preserving the rigid guide wall structure.
Solution Approach 2:
The spring arm acts as an intermediary element between the rigid guide wall structure and the operator's hand. It translates the positional information of the module (relative to the base) into tactile feedback through controlled deflection. The follower-cam-spring arm mechanism serves as a mediator that converts mechanical displacement into perceptible tactile signals without interfering with the primary guiding function of the rigid wall.
2Reliability
If the module is completely detached from the base, then electrical disconnection is achieved, but the operator cannot confirm the disconnection state without visual inspection
Solution Approach 1:
The feedback mechanism provides tactile confirmation of electrical disconnection through the follower-cam interaction. Specific cam profiles are designed to generate characteristic tactile sensations at critical positions, such as when electrical contacts are broken. This allows the operator to confirm disconnection state through touch alone, eliminating the need for visual inspection while adding only moderate mechanical complexity.
Solution Approach 2:
The system provides self-confirmation through the inherent mechanical interaction between the module, follower, and cams. The structure automatically generates tactile feedback signals that inform the operator of the connection state without requiring external monitoring devices or complex control systems. The mechanical elements serve their primary function while simultaneously providing diagnostic feedback.
3Ease of operation
If tactile feedback is provided through spring arm deflection, then operator awareness of separation state is improved, but additional components are added to the assembly
Solution Approach 1:
The feedback mechanism is merged with the existing attachment/detachment structure. The spring arm and follower are integrated into the module assembly, and the cams are incorporated into the base structure. This combining approach provides tactile feedback functionality while utilizing existing structural elements, thereby minimizing the increase in overall device complexity.
Solution Approach 2:
The spring arm mechanism serves multiple functions: it provides tactile feedback to the operator, maintains proper spacing between the module and base during insertion, and guides the follower along the cam profiles. This multi-functionality reduces the need for separate dedicated feedback components, thereby limiting the increase in device complexity while achieving the desired operator awareness.
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
The system provides reliable tactile feedback to operators, ensuring they are aware of the module's electrical connection or disconnection and impending complete separation, enhancing the detachment process with clear resistance cues.
Implementation Method 1
Each of the first and second cams are configured to cooperate with the follower to progressively displace the spring arm away from a neutral state of the spring arm as the follower moves against the cam during attachment or detachment of the two workpieces, the displacement of the spring arm thereby generating tactile feedback

AI summary
An assembly for attaching and detaching an electronics module from a base includes a feedback assembly that provides an operator with tactile feedback on the relative positioning of the module with the base during attachment or detachment of the module to or from the base. The feedback assembly includes cams on the electronics module and a follower attached to an end of a spring arm on the base. The spring arm forms a portion of a wall that guides movement of the module along the base during attachment or detachment of the module.
