Lever-Attached Electronic Component for Easy Connector Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector designs make it difficult to easily detach electronic components from electronic devices due to limited movement of connectors during rotation, leading to challenges in detachment.
Innovation Solution
The design includes a lever that is rotatable about a rotation axis, featuring a lever body with a recess that houses a protrusion of the electronic component, allowing the protrusion to move away from the axis when the lever is rotated, facilitating easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lever-fitting type connector with a cam groove and protrusion is used, then the connectors can be joined by rotating the lever, but the electronic component is not easily detached due to limited movement distance
Solution Approach 1:
The lever body extends in a radial direction orthogonal to the rotation axis, creating a lever arm that amplifies the rotational motion. This dimensional arrangement allows the protrusion to trace a larger arc path during lever rotation, increasing the effective movement distance of the connector without requiring longer linear travel. The radial extension transforms limited linear movement into amplified rotational displacement.
2Ease of operation
If the lever body extends from the rotation axis in a radial direction, then the protrusion can move away from the rotation axis during rotation, but the structure becomes more complex
Solution Approach 1:
The lever body simultaneously serves multiple functions: it acts as a rotational actuator to initiate detachment, provides a lever arm to amplify motion, guides the protrusion through its movement path, and maintains engagement during operation. This multi-functionality reduces the need for separate components, thereby simplifying the overall structure despite the radial extension geometry.
Solution Approach 2:
The lever body is designed with a recess that segments the interaction zone, allowing the protrusion to be housed and guided independently within the lever structure. This segmentation enables the lever to manage the detachment motion through controlled geometric constraints rather than complex mechanical linkages.

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 solution enables easy detachment of electronic components by allowing the protrusion to move away from the rotation axis, enhancing the mechanical strength and reliability of attachment while providing a smooth detachment process.
Implementation Method 1
a lever that is provided adjacent to the electronic component and is attached to the housing in a state of being rotatable about a rotation axis extending along the attachment surface

AI summary
An electronic device includes a housing including an attachment surface, an electronic component detachably attached to the attachment surface, and a lever attached to the housing in a state of being rotatable about a rotation axis adjacent to the electronic component and extending along the attachment surface. The lever has a lever body facing the electronic component in a direction where the rotation axis extends and extending along a radial direction orthogonal to the rotation axis. The lever body includes a recess recessed in a direction approaching the rotation axis of the lever along the radial direction. The electronic component includes a protrusion facing the recess, protruding in a direction toward the lever body, and being housed in the recess. By rotating the lever in a direction away from the attachment surface, the protrusion moves in a direction away from the rotation axis in the recess.
