Solution Overview

Problem

Existing intercom systems in broadcast, theater, and studio environments lack an intuitive and efficient method for selectively choosing and managing direct two-way communication and data exchange between multiple users and devices, leading to complexity in user interface and operation.

Innovation Solution

An intercom signal mixer with multiple inputs and outputs, channel controls, and a display that renders channel tiles for easy assignment and management of audio signals, allowing users to select and mix audio from external devices in a user-friendly carousel arrangement, enabling direct communication and data exchange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large number of devices are used to support more users in an intercom system, then the system capacity increases, but the complexity of selectively monitoring and choosing active components increases

Engineering Contradiction:
Improvesystem capacityVSAvoidcomplexity of selectively monitoring
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The intercom system is segmented into multiple independent channel tiles, each representing a specific external device or user channel. Each channel tile is a self-contained unit with its own controls and display, allowing operators to manage numerous channels through modular, organized segments rather than a monolithic complex interface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a traditional linear or hierarchical control layout to a two-dimensional grid of channel tiles. This spatial reorganization allows operators to access and monitor multiple channels simultaneously across the display surface, effectively adding a dimensional aspect to channel selection and monitoring that scales efficiently with system capacity.

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

2Productivity

If traditional intercom control interfaces are used, then device compatibility is maintained, but the speed and intuitiveness of selecting users for direct communication decreases

Engineering Contradiction:
Improvespeed of selecting usersVSAvoidintuitiveness of selection
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

Channel tiles utilize visual indicators including color coding to represent different channel states, active selections, and communication statuses. This visual language enables operators to rapidly identify and select channels based on color-coded information rather than text alone, significantly increasing selection speed and intuitiveness.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The system pre-organizes and displays all available channels in tile format with their current status visibly indicated before any selection action is required. This preliminary visual organization allows operators to immediately comprehend the communication landscape and make rapid selections without needing to navigate through multiple menus or search procedures.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If comprehensive channel control options are provided, then system functionality increases, but the user interface complexity increases

Engineering Contradiction:
Improvesystem functionalityVSAvoiduser interface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each channel tile encapsulates a complete set of control options for that specific channel, segmenting the overall control functionality into distributed, localized units. This segmentation allows comprehensive functionality to be available at each channel level without overwhelming the user interface, as controls are contextually organized within individual tiles rather than presented as a global complex menu structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The channel tile design implements a universal control paradigm where each tile provides the same comprehensive set of controls and options regardless of which channel it represents. This multi-functional tile template allows the system to support diverse functionality across numerous channels while maintaining a consistent, predictable interface pattern that reduces perceived complexity.

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

AI summary

An intercom signal mixer having a number of channel controls associated with a respective number of channel tiles rendered by a display. The assignment for the channel controls may be adjusted by a user using the channel tiles, by selecting a new assignment from a list of available assignments presented in a continuously-scrolling carousel arrangement.
