Extendable Phone Housing Joint Structure for Gap Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with extendable housings suffer from gaps that compromise aesthetics, user experience, and increase the risk of dust and foreign matter entry, affecting their service life.
Innovation Solution
The implementation of joint parts that move relative to the housings to fill gaps, combined with an actuating mechanism using elastic members and actuators to automate the process, ensuring a seamless appearance and preventing dust ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile phone housing is in a drawn-out state with a gap between housing parts, then the extendability function is achieved, but the appearance becomes less fine and user experience deteriorates
Solution Approach 1:
A filling component is introduced as an intermediary element between the first and second housing parts. This filling component moves to fill the gap formed when the housing is in the drawn-out state, thereby maintaining appearance fineness while preserving extendability functionality. The filling component acts as a mediator that resolves the contradiction between the gap necessary for extendability and the gapless appearance desired by users.
2Adaptability or versatility
If a gap is formed between housing parts in drawn-out state, then extendability is enabled, but leakproofness is reduced and dust entry increases
Solution Approach 1:
The filling component serves as a mediator that seals the gap between housing parts when in the drawn-out state. By moving into the gap, it restores leakproofness and prevents dust and foreign matter from entering the device, while still allowing the housing to extend when needed.
Solution Approach 2:
The filling component is designed to be movable rather than fixed, allowing it to dynamically adjust its position. It moves to fill the gap when the housing is drawn out, maintaining sealability, and can be repositioned when the housing needs to extend, thus resolving the contradiction between extendability and leakproofness through dynamic behavior.
3Shape
If joint parts move to fill gaps, then appearance and leakproofness are improved, but device complexity increases
Solution Approach 1:
The filling component is designed with multi-functionality, serving both aesthetic purposes (filling gaps for appearance) and protective purposes (sealing gaps for leakproofness). This universal component performs multiple functions simultaneously, reducing the need for separate mechanisms and thereby limiting the increase in device complexity.

AI summary
This application pertains to the field of communications technologies, and discloses an electronic device. The electronic device includes a first housing, a second housing, a display screen, and a first joint part. The display screen is disposed on the first housing and the second housing. There are a drawn-out state and a drawn-back state of the electronic device. When the drawn-back state of the electronic device is switched to the drawn-out state, the first housing and the second housing become farther from each other along a first direction, and the first joint part moves along a second direction to join a lateral wall of the first housing and a lateral wall of the second housing. The first direction is perpendicular to the second direction, and the first direction and the second direction both are parallel to a plane on which the display screen is located.
