Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid and elastic bodies, such as glass/ceramics and plastics, respectively, face challenges in being easily assembled and dismantled due to their inherent material limitations, where rigid bodies are fragile and costly to shape, while elastic bodies are susceptible to temperature and have inferior finishes.
Innovation Solution
A novel assembly structure featuring a rigid body with a chamber and opening, an elastic body with an indentation and through hole, and an interface element that allows easy connection and separation via an extension element and indentation, combining the advantages of both materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid bodies are joined using adhesives, then the joining strength is improved, but the ease of disassembly deteriorates
Solution Approach 1:
The adhesive joint is segmented into two separate functional elements: an adhesive layer providing bonding strength and a detachment layer providing easy separation capability. This segmentation allows the joint to exhibit both strong bonding during use and easy detachment when needed, resolving the contradiction between joining strength and ease of disassembly.
Solution Approach 2:
The detachment layer acts as an intermediary between the rigid substrate and the elastic body. This intermediate layer with low shear strength enables controlled separation while the adhesive layer maintains strong bonding, allowing the system to achieve both strong joining and easy disassembly through the mediating function of the detachment layer.
2Manufacturing precision
If rigid bodies are used, then the surface finish quality is improved, but the ease of shaping deteriorates
Solution Approach 1:
The product is segmented into two distinct material components: a rigid body providing high surface finish quality and an elastic body providing ease of shaping. Each material performs its optimal function in its designated region, resolving the contradiction between surface finish quality and ease of shaping by distributing these requirements to different material segments.
Solution Approach 2:
Different regions of the assembly have different material properties optimized for their specific functions: the rigid body region provides high surface finish quality where appearance and precision are critical, while the elastic body region provides ease of shaping where complex geometries and impact resistance are needed. This local quality differentiation resolves the contradiction.
3Reliability
If elastic bodies are used, then the impact resistance is improved, but the temperature resistance deteriorates
Solution Approach 1:
The assembly is segmented into a rigid body and an elastic body, each selected for their optimal temperature resistance properties. The rigid body material (such as metal or ceramic) provides high temperature resistance, while the elastic body provides impact resistance. This segmentation allows the system to achieve both temperature resistance and impact resistance by combining materials with complementary properties.
Solution Approach 2:
The invention creates a composite structure combining rigid and elastic materials with different thermal and mechanical properties. The rigid material component provides temperature resistance while the elastic material component provides impact resistance, achieving a composite system that exhibits both properties simultaneously, resolving the contradiction between temperature resistance and impact resistance.

AI summary
An assembly structure of a rigid body and an elastic body is provided. The rigid body made of glass or ceramics has a chamber and an opening exposing the chamber. The elastic body made of plastics has an indentation and a through hole inside the indentation. The assembly structure further contains an interface element attached to a bottom side of the chamber and has an extension element corresponding to the opening of the chamber. The interconnection between the rigid and elastic bodies is achieved by joining the extension element with the indentation so that the rigid and elastic bodies could be easily put together and separated. The advantages of the rigid body such as robust to deformation and fine surface finish are thereby combined with the advantages of the elastic body such as easy shaping and assembly.
