Segmented Mobile Phone Case Frame-Back Assembly for 3D Styling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone cases lack visual appeal and have expensive molds, with integrated case back panels and frames resulting in monotonous designs and high manufacturing costs.
Innovation Solution
A mobile phone case design where the case back panel and frame are separately manufactured components connected through through-portions and connecting portions, with a male-female interlocking structure and optional adhesive, enhancing strength and three-dimensional appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the case back panel and case frame are manufactured as an integrated structure using conventional injection molding, then the manufacturing process is simple, but the appearance becomes monotonous and outdated, lacking visual appeal
Solution Approach 1:
The mobile phone case is divided into two independently formed components: the case back panel and the case frame. These separate components are then connected through through-portions and connecting portions, allowing each part to be manufactured independently with different materials, colors, and transparencies, thereby achieving both manufacturing efficiency and enhanced visual appeal with three-dimensional effects
2Strength
If the case back panel and case frame are manufactured as an integrated structure, then the structural strength is sufficient, but the manufacturing mold cost becomes relatively expensive
Solution Approach 1:
By segmenting the mobile phone case into separately manufactured case back panel and case frame components, the patent eliminates the need for expensive integrated injection molding. The components are connected through through-portions and connecting portions with adhesive structures, maintaining structural strength while significantly reducing mold costs and allowing for more flexible manufacturing
3Shape
If the case back panel and case frame are connected through through-portions and connecting portions, then the visual sense of three-dimensionality is enhanced, but the connection strength must be ensured
Solution Approach 1:
The case is segmented into separately manufactured components connected through through-portions, creating visible three-dimensional effects. To ensure connection strength, the patent incorporates adhesive structures within the connecting portions that bond the case back panel and case frame, maintaining both aesthetic appeal and structural integrity
Solution Approach 2:
Adhesive structures are introduced as intermediary elements within the connecting portions to bond the case back panel and case frame. This intermediary connection method ensures sufficient connection strength while preserving the visual three-dimensional effect created by the separate component structure

AI summary
A mobile phone case includes a case back panel and a case frame fixedly connected to the case back panel, wherein the case back panel and the case frame are two independently formed components; wherein a plurality of through-portions are disposed at intervals around periphery of the case back panel; and a plurality of connecting portions, present in the same number as the plurality of through-portions, are disposed at intervals on a side of the case frame; wherein each of the plurality of connecting portions is correspondingly embedded in one of the plurality of through-portions to fixedly connect the case back panel to the case frame.
