Interposed Bracket for Mobile Device Connector Abuse Load Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile device connectors face challenges in withstanding increased forces, bending moments, and wear and tear without structural or electrical failure, and existing designs often deform or impair the device under such conditions.
Innovation Solution
A bracket is interposed between the mobile device housing and the electrical receptacle, providing structural reinforcement, electrical insulation, and flexibility to absorb forces and torque, featuring a conductive bracket body with an insulative sheath and fastener accommodations that allow for mechanical flexibility without physical or electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid connector receptacle is used to ensure structural strength, then the connector can withstand forces and torque, but the housing and internal structure may deform or be impaired under excessive forces
Solution Approach 1:
A bracket is introduced as an intermediary component between the connector receptacle and the housing. This bracket absorbs and distributes the forces and torque applied to the connector, preventing direct transmission of excessive forces to the housing and internal structure. The bracket acts as a mechanical mediator that protects the device while maintaining connector strength.
Solution Approach 2:
The bracket is designed with specific geometric parameters including an elongated opening and arcuate surfaces that allow controlled deformation and flexibility. These parameter changes enable the bracket to flex under excessive forces, absorbing energy while protecting the housing from damage.
2Strength
If a conductive bracket body is used to provide structural reinforcement, then the mechanical connection is strengthened, but electrical insulation between the housing and receptacle is compromised
Solution Approach 1:
The bracket assembly combines a conductive bracket body with an electrically insulative sheath. The conductive bracket body provides structural reinforcement and mechanical strength, while the insulative sheath surrounding portions of the bracket body maintains electrical insulation between the housing and receptacle. This composite structure resolves the contradiction between mechanical strength and electrical insulation.
3Stability of the object's composition
If a fixed rigid connection is used between the housing and receptacle, then structural stability is improved, but flexibility to absorb forces and torque is reduced
Solution Approach 1:
The bracket incorporates dynamic characteristics through its geometric design featuring an elongated opening and arcuate surfaces. This design allows the bracket to flex and adapt when excessive forces or torque are applied, providing controlled movement and energy absorption while maintaining overall structural stability during normal operation.
