Ergonomic Holder for Tablet Control in Agricultural Machinery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tablet computers with touch screens are difficult to operate with precision in shaky environments and are fragile, making them unsuitable for controlling agricultural machines and other equipment where precise control and durability are required.
Innovation Solution
A holder with grip means for a detachable tablet computer that includes ergonomic buttons and sensors, allowing for machine control without using the touchscreen, with wireless communication and a shading screen for improved usability and protection, enabling secure operation in challenging conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tablet computer with touchscreen is used to control agricultural machines, then the functionality and control capabilities are improved, but the ease of operation deteriorates in shaky environments due to difficulty of precise touchscreen operation
Solution Approach 1:
The holder serves as an intermediary device between the operator and the tablet computer. It provides physical buttons and controls that translate operator input into tablet commands, bridging the gap between the need for precise control and the limitations of touchscreen operation in shaky environments.
Solution Approach 2:
The invention replaces the touchscreen interface (electronic/optical system) with physical mechanical buttons and controls on the holder. This substitution provides tactile feedback and precise mechanical actuation that is superior to touchscreen operation when the device is moving or vibrating.
2Adaptability or versatility
If a tablet computer is used in agricultural machine environments, then the functionality is improved, but the reliability deteriorates due to fragility of the touchscreen device
Solution Approach 1:
The holder provides protective cushioning for the tablet computer before environmental stressors can cause damage. The protective case and mounting structure absorb shocks and protect the fragile touchscreen device from the harsh agricultural environment, preventing reliability issues before they occur.
Solution Approach 2:
The holder acts as a protective intermediary between the fragile tablet computer and the harsh external environment. It shields the device from physical damage while still enabling full functionality through its integrated controls and interface.
3Ease of operation
If a holder with physical buttons and controls is added to the tablet computer, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The system is segmented into distinct functional components: the tablet computer provides computing and display functions, while the holder provides physical controls and protection. This segmentation allows each component to be optimized independently and simplifies the overall system architecture.
Solution Approach 2:
The holder is designed as a multi-functional device that simultaneously provides physical controls, protection, mounting, and interface capabilities. This consolidation of multiple functions into a single accessory reduces overall system complexity compared to having separate components for each function.
