Touchscreen Control Panel for Loading Dock Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loading dock control panels often confuse operators with numerous operational choices, leading to errors and delays due to the complexity of interlocking equipment sequences, which can be inflexible and require specific configurations.
Innovation Solution
A touchscreen control panel that sequentially displays only the necessary operational choices for loading dock equipment, allowing operators to follow a preset sequence and providing flexibility by enabling stop or reversal of the dock sequence at any point, reducing operator confusion and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional control panels present all operational choices simultaneously, then operators have complete control flexibility, but operator confusion and errors increase due to complexity
Solution Approach 1:
The control panel segments operational choices into sequential displays, showing only one operational choice at a time based on the current dock state. This divides the complex control interface into manageable steps, reducing operator confusion while maintaining complete control flexibility through the sequential progression of displays.
Solution Approach 2:
The control panel dynamically adapts its display based on the current operational state and sequence position. Different displays are presented depending on which equipment is currently operational, making the interface responsive to system state rather than static, thereby reducing confusion without limiting operational flexibility.
2Reliability
If conventional control panels use fixed interlocking sequences, then equipment operation safety is improved, but adaptability to different scenarios is reduced
Solution Approach 1:
The control panel uses dynamic sequencing that adapts to different operational scenarios. The sequence of displays and enabled controls changes based on the current dock state, allowing the system to maintain safety through interlocking while providing flexibility to handle various operational requirements without fixed rigid sequences.
Solution Approach 2:
The control panel changes operational parameters and sequence requirements based on the current state of the dock and equipment. Different interlocking requirements and display sequences are activated depending on which equipment is operational, maintaining safety while enabling adaptability to different scenarios.
3Adaptability or versatility
If conventional control panels display all controls at once, then complete operational control is available, but operator time for decision-making increases
Solution Approach 1:
The control panel segments operational choices into sequential displays, presenting only one relevant control option at a time based on the current dock state. This segmentation reduces the cognitive load and decision-making time required by operators while maintaining complete operational control flexibility through the sequential progression of available choices.

AI summary
Systems and associated methods for controlling operation of loading dock equipment are disclosed herein. In some embodiments, the system and associated methods can be used to control operation of loading dock equipment (e.g., a vehicle restraint, a dock door, a dock leveler, etc.) according to a preset sequence of operations. The system can include a display screen that sequentially presents a series of graphical control elements (e.g., touch-sensitive buttons) that enable operation of the loading dock equipment in an appropriate sequence. Additionally, the visual appearance and/or sequence of presentation of the graphical control elements indicate the proper sequence of selection to the user, thereby reducing user confusion and simplifying the operation of the loading dock equipment.
