Solution Overview

Problem

Existing electronic devices face difficulty in easily detaching electronic components due to limited movement of connectors upon lever rotation, making detachment cumbersome.

Innovation Solution

The electronic device incorporates a lever that is rotatable about a rotation axis, featuring a recess and protrusion configuration allowing for enhanced detachment by rotating the lever away from the attachment surface, with protrusions moving along the recess to facilitate easy removal of the electronic component.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a lever-fitting type connector is used with a cam groove and protrusion, then the connectors can be joined by rotating the lever, but the movement distance of the connector is short and it is difficult to greatly separate the connectors

Engineering Contradiction:
Improveease of detachmentVSAvoidmovement distance of connector
Core Design Contradiction:
Ease of operationVSLength of moving object

Solution Approach 1:

The lever body extends in a radial direction from the rotation axis, and the recess is configured to move the protrusion in a direction away from the rotation axis when the lever is rotated. This radial dimensionality change allows the protrusion to travel a greater distance along the recess, achieving larger separation distance while maintaining the rotary lever mechanism.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The invention changes the geometric parameters of the lever mechanism by configuring the recess to extend in a direction away from the rotation axis, allowing the protrusion to move through a longer path during lever rotation. This parameter modification enables greater connector separation while maintaining the ease of rotary operation.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the lever is configured to move the electronic component away from the attachment surface by rotation, then detachment is facilitated, but the structure becomes more complex

Engineering Contradiction:
Improveease of detachmentVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lever body and recess are integrated into a single component, combining the lever arm and the guiding feature into one piece. This merging reduces the number of separate parts and simplifies the overall structure while maintaining the functionality of moving the protrusion during rotation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The recess is configured to automatically guide the protrusion along its movement path during lever rotation, eliminating the need for additional guiding mechanisms or complex constraint structures. The geometry of the recess itself provides the guiding function, simplifying the overall mechanism.

Inventive Principle:
Principle #25Self-service

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.
