Solution Overview

Problem

Existing methods for setting parameters in communication units connected to sound signal processing devices are inconvenient, requiring multiple physical operators that are costly and difficult to arrange, and often require re-setting when the unit is replaced, with limitations in usability when the host device lacks setting functions or the user is unfamiliar with them.

Innovation Solution

A communication unit with a control unit that includes a CPU, flash memory, and RAM, featuring a first operator for selecting between physical and host-supplied settings, and a second operator for parameter configuration, allowing parameter values to be set using either physical switches or host-provided values, with a GUI for editing and storing settings for convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If physical operators (DIP switches or dials) are provided for setting all parameters, then parameter setting can be performed without host device functions, but the number of operators increases leading to higher cost and difficult arrangement

Engineering Contradiction:
Improveparameter setting capabilityVSAvoidnumber of physical operators
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the parameter setting function into two segments: essential parameters that can be set via physical operators and non-essential parameters that use host device functions. This segmentation allows the physical operator count to be reduced while maintaining necessary adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The host device's parameter setting function serves multiple purposes: it configures communication units, stores configuration data, and enables parameter inheritance. This multi-functionality reduces the need for dedicated physical operators on each communication unit.

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

2Reliability

If physical operators are provided for each parameter, then settings can be maintained when units are replaced, but re-setting is required when units are replaced due to operator limitations

Engineering Contradiction:
Improvesetting persistenceVSAvoidsetting convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a copying mechanism where parameter settings from a host device are automatically copied to replacement communication units. This eliminates manual re-setting while ensuring setting persistence, as the host device stores and reproduces configuration data.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

Parameter settings are preliminarily stored in the host device before unit replacement occurs. When a unit is replaced, the pre-stored settings are automatically applied, eliminating the need for post-replacement configuration work.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If host device parameter setting functions are used, then the number of physical operators can be reduced, but the communication unit cannot be used in sound signal processing devices lacking corresponding setting functions

Engineering Contradiction:
Improvenumber of physical operatorsVSAvoiddevice compatibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The communication unit is designed to be self-sufficient by incorporating physical operators for essential parameters. This allows the unit to configure itself independently when connected to host devices that lack parameter setting functions, ensuring broad device compatibility.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements a dynamic parameter setting system that adapts its operation mode based on the host device's capabilities. When host device functions are available, the system uses them; when not available, it falls back to physical operators, optimizing for both complexity reduction and compatibility.

Inventive Principle:
Principle #15Dynamics

4Measurement precision

If comprehensive host device knowledge is required for parameter setting, then precise configuration can be achieved, but users unfamiliar with host functions cannot perform appropriate setting operations

Engineering Contradiction:
Improveparameter configuration accuracyVSAvoiduser operation difficulty
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The physical operators serve as an intermediary interface between the user and the communication unit's parameters. This intermediary provides tactile, intuitive control for essential parameters without requiring users to understand complex host device functions, while still achieving precise configuration.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A communication unit (100) connected to a host device is provided with: a communication circuit (102) which performs data communication on the basis of the value of a first parameter that has been set; a first operating element (111) which is selectively set by a user to one of a first state and a second state which are physically identified; a second operating element (112) which is set by the user to a physical state indicating the value of the first parameter; and a control unit (101). At the time of starting up the data processing unit, the control unit (101) sets the value of the first parameter indicated by the physical state of the second operating element (112) in the communication circuit (102) if the first operating element (111) is in the first state, or sets the value of the first parameter supplied from the host device in the communication circuit (102) if the first operating element (111) is in the second state.
