Sliding Body Nesting Mechanism for Coplanar Handheld Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electronic devices with sliding designs often suffer from a lack of integrity in appearance due to height differences and exposed sliding grooves, compromising their aesthetic appeal and functionality.
Innovation Solution
A handheld electronic device design featuring a first body and a second body with a recess, utilizing a transmission mechanism comprising a first plate, a second plate, and a rotating member, where the first body slides into the recess, driven by the plates and elastic members, maintaining coplanarity and eliminating the need for a sliding groove, and utilizing magnetic elements for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display screen is slid relatively to the keyboard to expose the keyboard for input operation, then the ease of operation is improved, but the appearance integrity deteriorates due to height difference and exposed sliding groove
Solution Approach 1:
The first body is nested into the recess of the second body during sliding operation. When the display screen slides to expose the keyboard, the first body enters the recess of the second body, maintaining coplanarity of the outer surfaces and eliminating the need for exposed sliding grooves, thus preserving appearance integrity while enabling input operation.
Solution Approach 2:
The sliding mechanism transitions from a simple linear slide to a three-dimensional motion where the first body both slides and enters the recess of the second body. This dimensional change allows the maintaining of coplanar outer surfaces while providing sufficient exposure of the keyboard for operation.
2Ease of operation
If a sliding groove is configured on the first body or second body to enable relative sliding, then the ease of operation is improved, but the appearance conciseness deteriorates due to exposed sliding groove
Solution Approach 1:
The sliding mechanism is hidden by nesting the first body into the recess of the second body. The outer surfaces remain coplanar throughout the sliding operation, completely eliminating the need for exposed sliding grooves on either the first or second body, thus maintaining appearance conciseness while enabling smooth sliding operation.
Solution Approach 2:
The sliding groove that would normally be exposed on the surface is extracted and replaced by a recess structure. The recess accommodates the sliding motion internally, removing the visual defect of exposed grooves while preserving the sliding function.

AI summary
A handheld electronic device including a first body, a second body and a transmission mechanism is provided. The second body is stacked with the first body. The second body has a recess at a side facing the first body. The transmission mechanism includes a first plate, a second plate and a rotating member. The first plate is fixed on the first body. The second plate is slidingly coupled to the first plate. An end of the rotating member is pivoted on the second body, and another end of the rotating member is pivoted on the second plate. When the first body slides with respect to the second body toward the recess, the rotating member rotates and drives the first body enters the recess.
