Touchscreen operation switch, equipment management device, and equipment-management-screen generation method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touchscreen-based equipment management systems for large buildings are prone to erroneous operations due to the complexity of two-step processes required to change the operational state of equipment, which can lead to unintended changes when administrators accidentally interact with the management screens.
Innovation Solution
A touchscreen operation switch and equipment management device that utilizes a display-information generator and action-control-information generator to create a management screen with laterally elongated icons, allowing administrators to perform intended operations with a single slide operation within a defined detection area, reducing the likelihood of erroneous changes by setting specific slide-operation detection lines and areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a two-step operation process is implemented to prevent erroneous operations, then operational reliability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent implements dynamic response based on touch duration. The system distinguishes between intentional operations (longer touch duration) and accidental touches (shorter touch duration) by monitoring how long the user maintains contact with the touchscreen. This dynamic temporal discrimination allows the system to execute operations selectively, preventing erroneous operations while maintaining simplicity for intentional actions.
Solution Approach 2:
The system provides visual feedback through display elements that change state based on touch duration. When a touch is detected, the system displays a prompt or changes the icon appearance to indicate that a longer touch is required for operation. This feedback mechanism guides the user to perform intentional operations with adequate duration, while accidental short touches are automatically ignored.
2Reliability
If a two-step operation process is implemented to prevent erroneous operations, then operational reliability is improved, but ease of operation worsens
Solution Approach 1:
The system uses dynamic touch duration detection to differentiate between intentional and accidental operations. By monitoring the temporal characteristic of the touch input, the system executes operations only when the touch duration exceeds a predetermined threshold, thereby preventing erroneous operations while maintaining simplicity for intentional actions without requiring multiple discrete steps.
Solution Approach 2:
The patent changes the operational parameter from binary (touch/not touch) to continuous (touch duration). By measuring and comparing the duration of the touch against a threshold value, the system creates a smooth transition between accidental and intentional operations. This parameter change eliminates the need for complex multi-step confirmation processes while maintaining reliability.
3Ease of operation
If traditional touchscreen icons are used, then ease of operation is improved, but reliability deteriorates due to accidental touches
Solution Approach 1:
The patent introduces temporal dynamics to traditional static touchscreen icons. The icons respond differently based on the duration of the touch input. Short touches are registered as selection or highlighting, while longer touches trigger the actual operation. This dynamic behavior allows the same icon to serve multiple functions based on interaction duration, preventing accidental operations while maintaining ease of use for intentional actions.
Solution Approach 2:
The system employs periodic sampling of touch duration to determine operation execution. Rather than responding immediately to any touch, the system monitors the touch over a predetermined time period and makes the decision to execute based on whether the touch persists throughout this period. This periodic verification mechanism prevents accidental operations while maintaining simplicity for intentional actions.

AI summary
An equipment-management device associated with at least one of multiple pieces of equipment in a building under management, the equipment-management device including a display-information generator, a touchscreen, and an action-control-information generator. The display-information generator generates display information on a management screen wherein icons are arranged, each of the icons including an outer frame and a first area set at one end along the major axis within the outer frame. The touchscreen displays the display information and receives an input of information relating to an operation performed on the management screen. Upon detecting that a slide operation performed on one of the icons of the management screen from the first area through a first slide-operation detecting line set inside the outer frame excluding the first area, the action-control-information generator generates action-control information that switches the power supply of the corresponding equipment on or off.
