Housing Assembly Tailbone Structure for Rear Cover Gap Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Leather rear covers in electronic devices often have a poor match with middle frames, resulting in a large gap that affects aesthetics and user experience.
Innovation Solution
A housing assembly design that includes a middle frame, support, and decorative part, where the support is connected to the middle frame and features a tailbone to reduce the gap and enhance aesthetics, with the tailbone providing protection for the decorative part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a leather rear cover is mounted to a middle frame, then the rear cover can be installed on the electronic device, but a relatively large gap is present between the leather rear cover and the middle frame, affecting aesthetics
Solution Approach 1:
The support is divided into a support body and a tailbone portion. The tailbone protrudes from the support body to fill the gap between the rear cover and the middle frame, thereby reducing the visible gap and improving the overall fit without requiring complex manufacturing processes
Solution Approach 2:
The tailbone extends in a direction perpendicular to the main body of the support, utilizing the thickness dimension to bridge the gap between the rear cover and the middle frame. This dimensional extension allows for gap reduction without affecting the planar fit of the rear cover
2Reliability
If the decorative part is mounted on the support, then the rear cover can be assembled, but the decorative part may curl or damage at its end, affecting aesthetics
Solution Approach 1:
The tailbone is designed to protrude from the support body in advance, creating a protective structure before the decorative part is mounted. This preliminary structural preparation ensures that the decorative part is protected from curling or damage at its end, maintaining both reliability and aesthetics

AI summary
A housing assembly includes a middle frame, a support and a decorative part. The middle frame includes a middle frame body and a border frame, where the border frame is connected to an outer edge of the middle frame body. The support includes a support body and tailbones. The support body includes a first support surface and a second support surface, where the first support surface and the second support surface face away from each other. The tailbone is connected to an outer edge of the support body. The tailbone includes a protrusion with the protrusion protruding from the first support surface. The decorative part is mounted on the first support surface with an end of the decorative part connected to the tailbone. The support is mounted on the middle frame with the second support surface facing the middle frame.
