Solution Overview

Problem

Existing remote control units for industrial trucks lack ergonomic design, leading to inefficient operation and potential safety hazards in demanding work environments, as they often require complex hand movements and accidental data transmission.

Innovation Solution

A remote control unit with a grip element and functional element that allows one-handed operation using fingers, incorporating a scanning unit, acceleration sensor, and display to enable efficient control and data acquisition without reaching, and differentiate guided movements from random movements for intuitive control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a remote control unit requires complex hand movements for operation, then control functionality can be achieved, but operator safety and efficiency deteriorate due to increased operational complexity and potential for error

Engineering Contradiction:
Improveease of operationVSAvoidsafety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The remote control unit automatically detects guided movements through the acceleration sensor and triggers scan/read operations without requiring the operator to manually activate them. The system serves itself by autonomously determining when data capture should occur based on detected movement patterns, eliminating the need for complex manual activation sequences while maintaining safety through intuitive control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces complex mechanical control sequences with an acceleration sensor-based detection system. Instead of requiring operators to press multiple buttons or perform complex hand movements to initiate scanning, the system uses the acceleration sensor to automatically detect guided movements and trigger appropriate functions, substituting mechanical interaction with automated sensing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If a scan unit is continuously active to capture data, then data acquisition capability is improved, but accidental data transmission increases due to unintended triggering

Engineering Contradiction:
Improvedata acquisition efficiencyVSAvoiddata transmission accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The scan/read unit's activation state is dynamically adjusted based on detected movement patterns. Rather than being continuously active or completely inactive, the system transitions between states based on whether guided movements are detected. This dynamic approach allows the scan unit to be active during legitimate guided movements while remaining inactive during accidental movements, optimizing both productivity and reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The acceleration sensor provides continuous feedback about the remote control unit's movement state. This feedback is processed to determine whether a movement represents an intentional guided action or an accidental occurrence. The system uses this feedback loop to intelligently control scan/read unit activation, ensuring data is captured during intentional movements while preventing accidental transmission.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If multiple control elements are provided for different functions, then operational versatility is improved, but device complexity increases requiring more components and interface elements

Engineering Contradiction:
Improvecontrol functionalityVSAvoidcontrol unit structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The acceleration sensor serves multiple functions within the remote control unit. It detects guided movements for triggering scan/read operations, distinguishes between intentional and accidental movements, and provides feedback for controlling the activation state of the scan unit. This multi-functional use of a single sensor reduces device complexity while maintaining versatile control capabilities.

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

Solution Approach 2:

The patent merges the movement detection function and the scan/read activation control into a single integrated system. Rather than having separate control elements for detecting movements and separate elements for triggering scanning, the acceleration sensor and control logic are combined to automatically link movement detection with scan unit activation, reducing the number of discrete components and simplifying the overall device structure.

Inventive Principle:
Principle #5Merging (Combining)
