Electronic Device Connection Structure for Gap-Resilient Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connections in electronic devices, such as those in computers and mobile phones, are prone to gaps forming between structural members due to scenarios like falling, leading to poor contact and overall device performance.
Innovation Solution
A connection structure featuring a metal structural member with through grooves that recess away from the middle frame and protrude towards it, allowing a fastener to securely connect and absorb gaps, combined with convex hulls for improved contact points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw connection is used to connect the metal structural member and the circuit board, then the electrical connection is implemented, but gaps easily form between the structural member and the circuit board in scenarios such as falling, causing poor contact
Solution Approach 1:
The patent applies the dynamics principle by making the metal structural member elastic through laser cutting slots that allow it to deform and recover. This elastic deformation enables the structural member to adapt to gaps formed during falling scenarios, maintaining continuous contact with the circuit board and middle frame without requiring rigid fastening
Solution Approach 2:
The patent changes the physical state of the metal structural member from rigid to elastic by creating slots that allow controlled deformation. This parameter change in flexibility enables the structural member to absorb impact and maintain electrical contact under varying conditions
2Stability of the object's composition
If the metal structural member is rigidly connected to the circuit board, then the electrical connection is stable, but gaps form during falling scenarios due to lack of flexibility
Solution Approach 1:
The patent transforms the rigid connection into a dynamic, flexible connection by laser cutting slots in the metal structural member. This allows the member to bend and recover elastically, maintaining stable electrical contact while accommodating gaps that form during falling scenarios
3Reliability
If through grooves are added to the metal structural member to absorb gaps, then contact reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent segments the metal structural member by laser cutting slots that divide the continuous metal into separated regions. This segmentation creates flexible edges that can deform independently to absorb gaps while maintaining overall structural integrity and electrical connectivity
Solution Approach 2:
The patent replaces complex mechanical gap-absorption mechanisms (such as separate elastic components or adjustment mechanisms) with a simpler solution: laser-cut slots in the metal member itself that provide inherent flexibility through elastic deformation

AI summary
Embodiments of this application provide a connection structure and an electronic device. The electronic device includes at least a middle frame, a metal structural member, and a fastener; the metal structural member has a first through hole, the middle frame has a second through hole, and the fastener passes through the first through hole and the second through hole; at least one through groove is provided on the metal structural member, a surface of the through groove facing away from the middle frame is recessed, and the through groove extends to at least one outer edge of the metal structural member; and a surface of the through groove facing the middle frame is protruded. In this way, existence of a gap between the metal structural member and the middle frame in scenarios such as falling can be avoided, and a problem of poor overall performance of the electronic device.
