Insertion Terminal Support Plate Inclined Surface Force Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face instability and movement issues due to excessive shaking of insertion jacks, which can lead to poor support and potential damage, especially when external forces are applied.
Innovation Solution
The electronic device incorporates a support plate part with a step difference surface and an inclined surface that transmits the shaking force to the body part, providing stable support by distributing the force effectively and using a non-deformable, high-rigidity material like stainless steel to prevent corrosion and ensure secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple support structure is used for the insertion terminal, then the device complexity is reduced, but the insertion terminal becomes unstable and shakes excessively when force is applied
Solution Approach 1:
The support plate part extends in multiple dimensions within the housing, creating a three-dimensional support network. The plate has varying thickness and extends along different axes, providing stability in multiple directions simultaneously without adding complex mechanical structures.
Solution Approach 2:
The support structure is divided into distinct functional zones: the support plate part for distributing forces, the inclined surface for force redirection, and the step difference surface for positional support. Each segment performs a specific function, allowing the overall structure to be simple yet effective.
2Ease of manufacture
If a deformable material is used for the support plate part, then the device can be made lighter and easier to manufacture, but the support plate cannot effectively transmit shaking force to the body part
Solution Approach 1:
The material properties of the support plate part are optimized by selecting materials with specific rigidity parameters. The plate is designed with controlled thickness variations and geometric parameters that enable effective force transmission while maintaining manufacturability and appropriate weight.
3Device complexity
If the support plate part directly contacts the insertion terminal without structural features, then the device complexity is reduced, but the force distribution is insufficient and the insertion terminal moves excessively
Solution Approach 1:
The support plate utilizes the third dimension (thickness variation) to create mechanical advantage. By varying the plate thickness and creating three-dimensional geometric features like inclined surfaces and step differences, the structure provides reliable force distribution without adding complex multi-component assemblies.
4Stability of the object's composition
If high-rigidity materials like stainless steel are used for the support plate part, then the force transmission and stability are improved, but the device weight increases
Solution Approach 1:
High-rigidity material is used specifically for the support plate part where force transmission is critical, while other parts of the device can use lighter materials. The support plate's thickness is optimized to provide necessary rigidity only in the regions where structural support is needed, reducing overall weight while maintaining stability.

AI summary
An electronic device is provided which includes an insertion terminal, a body part, and a support plate part. The insertion terminal has an insertion hole into which an insertion jack is inserted. The body part supports the insertion terminal at one side of the insertion terminal. The support plate part has a support surface being a surface opposite to the insertion terminal and supports the insertion terminal at the other side of the insertion terminal. The body part has an opposite surface opposite to the support surface, a step difference surface having a step difference with the opposite surface and placed to be deeper from the insertion hole on the basis of an insertion direction of an insertion jack than the opposite surface, and an inclined surface joining the opposite surface and the step difference surface. The support plate part transmits the force by which the insertion terminal shakes, to the body part through the inclined surface.
