Bonded Object Manufacturing Using Viscosity-Adjustable Adhesive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for bonding objects with mismatched surface shapes struggle to maintain appropriate thickness of the bonding agent, leading to inadequate bonding when the shapes of the surfaces to be bonded do not match.
Innovation Solution
A method and apparatus that utilize a bonding agent capable of changing viscosity, where the agent is supplied and adhered to the surfaces, and the second object, being more flexible, is deformed against the agent to ensure proper bonding, with optional thickening and fixing steps to maintain desired thickness and adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a bonding agent is supplied over flat and curved portions of an object and viscosity is increased on the flat portion to maintain thickness, then the bonding agent can fill the portion between the object and cover on the curved portion, but the bonding agent thickness becomes inappropriate when the shapes of surfaces to be bonded do not match
Solution Approach 1:
The bonding agent's viscosity is made dynamic rather than static. The patent employs a viscosity-adjustable bonding agent that can change its viscosity characteristics in response to different surface geometries, allowing it to maintain appropriate thickness on flat portions while flowing to fill gaps on curved portions, thereby resolving the contradiction between thickness control and surface shape adaptability
Solution Approach 2:
The patent changes the viscosity parameter of the bonding agent based on the surface geometry. By adjusting the viscosity parameter dynamically or spatially, the bonding agent can adapt to different surface shapes (flat vs. curved) while maintaining appropriate bonding thickness, thus solving the problem of incompatible surface shapes with fixed viscosity bonding agents
2Strength
If the second object is made more flexible to deform against the bonding agent, then effective bonding of mismatched surfaces is achieved, but the bonding agent may not maintain appropriate thickness without viscosity control
Solution Approach 1:
The bonding agent's viscosity is adjusted in advance before the deformation process. By pre-adjusting the viscosity to an appropriate level, the bonding agent is prepared to maintain its thickness during the subsequent deformation of the flexible second object, ensuring both bonding strength and thickness control are achieved
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective bonding of surfaces with mismatched shapes by applying load and deforming the second object, ensuring the bonding agent maintains the required thickness and adherence, even when shapes do not match.
Implementation Method 1
a bonding agent supply step of supplying the bonding agent R to the first bonding surface Cs or the second bonding surface Ts
Implementation Method 2
a loading step of applying a load to and deforming the second object T against the bonding agent R that closely adheres to the first bonding surface Cs
Implementation Method 3
a bonding agent close adherence step of making the bonding agent closely adhere to the required portion of the first bonding surface Cs and Ts

AI summary
A bonded object manufacturing apparatus is for manufacturing a bonded object in which a first object and a second object, which is more flexible than the first object, are bonded by a bonding agent, viscosity of which is variable, and includes: a bonding agent supplier that supplies the bonding agent to a first or second bonding surfaces; a thickening unit that increases the viscosity of the bonding agent; and a loading unit that applies a load to and deforms the second object against the bonding agent that closely adheres to the first bonding surface and becomes harder than the second object. In a method for manufacturing a bonded object, the first and second bonding surfaces are brought close to each other to hold the bonding agent therebetween, the bonding agent closely adheres to a required portion of the first bonding surface, and the second object is loaded and deformed against the bonding agent that closely adheres to the first bonding surface and is harder than the second object.
