Solution Overview

Problem

The integration of larger lens modules in portable electronic devices for improved photography compromises the device's lightness and thinness, necessitating a solution to enhance imaging quality while minimizing the volume occupied by the lens module and optimizing user interface updates.

Innovation Solution

A user interface update method that selectively updates only visible interface components, processing less data and reducing update delays by maintaining the state of invisible components, thus improving update efficiency and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all interface components are updated during user interface updates, then the completeness of interface updates is improved, but the update time and processing overhead increase

Engineering Contradiction:
Improvecompleteness of interface updatesVSAvoidupdate time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments interface components into two categories: visible components and invisible components. By dividing the update scope into these segments, the system only updates visible components during user interactions, while maintaining invisible components in their current state. This segmentation resolves the contradiction by allowing complete updates of necessary components without the overhead of updating all components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by updating only the necessary subset of interface components (visible ones) rather than performing excessive updates on all components. During user interactions, the system selectively updates only those components that the user can actually see and interact with, reducing unnecessary processing while maintaining the perceived completeness of the interface update.

Inventive Principle:
Principle #16Partial or excessive action

2Productivity

If visible interface components are updated selectively, then the update efficiency is improved, but the complexity of determining visibility increases

Engineering Contradiction:
Improveupdate efficiencyVSAvoidvisibility determination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent performs preliminary action by pre-determining the visibility status of interface components and storing this information in advance. The system maintains a visibility state for each component, which is determined beforehand based on the interface layout and user perspective. This preliminary determination simplifies the update process, as the system only needs to check the pre-stored visibility information rather than calculating visibility during each update operation.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If more lens modules with larger volume are assembled, then the photographing experience is improved, but the device weight and volume increase

Engineering Contradiction:
Improvephotographing experienceVSAvoiddevice weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent uses copying by creating virtual representations of lens modules and their optical paths through software simulations. Instead of physically assembling multiple large-volume lens modules, the system uses computational photography techniques and software algorithms to simulate the effects of multiple lenses. This virtual copying allows the device to achieve advanced photographing capabilities without the physical weight and volume of multiple large lens assemblies.

Inventive Principle:
Principle #26Copying

AI summary

This application provides a user interface update method and an electronic device. In a user interface update process, the electronic device may update only data of an interface component visible to a user, and may not update data of an interface component invisible to the user. In a process of updating a user interface once, the electronic device needs to process less interface component data, efficiency of updating the user interface is higher, time consumption and a delay of refreshing the user interface are shorter, energy consumption of displaying the user interface by the electronic device according to the user interface update method is lower, and user experience is better.
