Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the manufacturing of terminal devices, such as mobile phones and tablets, a small gap between the front camera and the screen can lead to scratching issues during assembly, which are difficult to predict and correct using traditional physical verification methods, resulting in increased product design return cycles and material costs.
Innovation Solution
An assembly verification method that uses computer simulations to determine the coordinates of high-risk assembly positions and gap value distribution intervals, allowing for virtual prediction of interference between the front camera and the screen, enabling timely design adjustments and reducing manual assembly errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the gap between the front camera and the screen is reduced to increase screen-to-body ratio, then the screen-to-body ratio is improved, but the risk of scratching during assembly increases
Solution Approach 1:
The patent applies preliminary action by performing computer simulation and virtual verification at the design stage to predict potential scratching issues before actual assembly. The system calculates gap value distribution intervals and identifies high-risk assembly positions in advance, allowing designers to adjust tolerance dimensions before manufacturing, thus preventing scratching problems rather than detecting them during production.
Solution Approach 2:
The patent uses copying by creating a virtual model of the assembly process through computer simulation. Instead of physically assembling components to verify gaps, the system generates a digital replica that replicates the assembly process, calculates gap distributions, and predicts scratching risks without physical contact between components, thereby eliminating the harmful scratching effect during verification.
2Measurement precision
If traditional physical verification methods are used to detect assembly interference, then detection accuracy is improved, but the product design return cycle increases and material costs increase
Solution Approach 1:
The patent replaces the mechanical verification system with a computer-based simulation system. Instead of physically assembling components to detect interference (mechanical method), the system uses computer algorithms to calculate gap value distribution intervals and predict interference (digital method). This substitution maintains detection accuracy while eliminating the time-consuming physical assembly and disassembly cycles.
Solution Approach 2:
The patent applies preliminary action by performing interference detection at the design stage through virtual verification rather than waiting for the production stage. The system calculates gap distributions and identifies potential interference before manufacturing begins, allowing design adjustments to be made without incurring production delays or material waste associated with traditional post-design verification.
3Reliability
If physical verification methods are used to predict assembly interference, then detection capability is improved, but manpower costs and material costs increase
Solution Approach 1:
The patent uses copying by creating a virtual model that replicates the assembly process and interference conditions without requiring physical components. The computer simulation generates gap value distribution intervals and predicts interference using digital representations of components, eliminating the need for physical prototypes, test materials, and manual assembly operations, thereby reducing both material consumption and manpower requirements while maintaining prediction reliability.
