Solution Overview

Problem

Existing control stations for aerial platforms, such as lifting platforms, face challenges in effectively communicating with users due to ambient noise and visual distractions, leading to potential misunderstandings and safety risks, especially for novice operators.

Innovation Solution

A control station with a haptic interface that provides kinesthetic and vibrotactile feedback based on the state and position of the controlled device, allowing users to receive contextual and understandable messages through tactile sensations, reducing reliance on auditory and visual cues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If auditory signals (beeps) are used to signal the state of the aerial work platform, then information can be transmitted to the user, but the signals are difficult to distinguish from other noises on the construction site

Engineering Contradiction:
Improveinformation transmission to userVSAvoidambient noise interference
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary device (portable control station with display and haptic feedback) that mediates between the aerial work platform and the user. This intermediary processes information from the platform and presents it through multiple channels (visual display, haptic feedback, auditory signals), overcoming the limitation of direct auditory signals being lost in ambient noise.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The portable control station implements feedback mechanisms where the user interacts with the device through touch inputs, and the system responds with haptic feedback and visual displays showing the current state of the aerial work platform. This closed-loop feedback ensures the user receives clear, unambiguous information about platform status.

Inventive Principle:
Principle #23Feedback

2Loss of information

If visual indicator lights are used to show the state of the aerial work platform, then information can be transmitted to the user, but the lights are made difficult to read by the light environment and dirt

Engineering Contradiction:
Improveinformation transmission to userVSAvoidlight environment and dirt interference
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The portable control station serves as an intermediary that receives data from the aerial work platform and displays it on a screen with adjustable characteristics. The display can be positioned and oriented optimally, and its brightness and contrast can be adjusted to overcome environmental light conditions and dirt accumulation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The display device on the portable control station allows parameter changes in terms of brightness, contrast, and positioning. These parameter adjustments enable the visual information to remain readable under various lighting conditions and when the control station itself becomes dirty during construction work.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If traditional control interfaces are used, then the control station can be simple in structure, but the communication with the user is not efficient and safe, especially for novice operators

Engineering Contradiction:
Improveuser understanding and safetyVSAvoidcontrol station structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The portable control station integrates multiple functions into a single device: it serves as a display unit, a haptic feedback device, an input interface, and a communication bridge between the user and the aerial work platform. This multi-functionality improves ease of operation while consolidating rather than increasing overall device complexity.

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

Solution Approach 2:

The patent replaces traditional purely mechanical or simple electrical control interfaces with a more advanced system that incorporates haptic feedback technology and digital display. This substitution provides richer communication with the user through tactile sensations that convey system state and warnings, significantly improving safety and ease of operation for novice users.

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