Solution Overview

Problem

Devices with limited display screens, such as watches, struggle to effectively display historical and future information in a practical manner.

Innovation Solution

The implementation of complication data objects and templates allows applications to efficiently display additional information on a watch face by configuring style windows and communicating with companion devices to update data based on user preferences and system considerations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a list format is used to display historical and future information, then information completeness is improved, but display practicality deteriorates due to limited screen size

Engineering Contradiction:
Improveinformation completenessVSAvoiddisplay practicality
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent segments information display into multiple hierarchical levels (first level complications showing summary information, second level complications showing detailed information). This allows comprehensive information to be organized in manageable segments that fit within limited screen space while maintaining accessibility to all data through structured navigation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a hierarchical dimension to the display structure, organizing information across multiple levels rather than attempting to display all information linearly on a single level. This dimensional approach allows complete information to be conveyed through structured layers that can be accessed systematically within the constraints of a small watch face.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple screens are displayed simultaneously on a wearable device, then information accessibility is improved, but device complexity increases

Engineering Contradiction:
Improveinformation accessibilityVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple information screens into a single integrated watch face display by using complications that can show both summary and detailed information in different states. This consolidation reduces the need for multiple separate screens while maintaining information accessibility through a unified interface that combines various data types in coordinated displays.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal complication structure that can serve multiple functions - displaying summary information, detailed information, historical data, and future information within the same display element. This multi-functional approach eliminates the need for separate dedicated screens for each type of information, reducing overall interface complexity while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Systems, methods, and devices can allow applications to provide complication data to be displayed in a complication of a watch face. A client application can create a complication data object according to a template to efficiently select how the complication data is to be displayed. For example, a complication controller on the watch can receive new data and determine which template to use. The complication data object can be sent to a display manager that can identify the selected template and display the data according to the template.
