Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held power tools lack an effective means to provide operators with a clear and concise overview of their operational readiness, particularly regarding charging status, temperature, and wear conditions, which can lead to unexpected tool failures during use.
Innovation Solution
A user interface with a device status output element that combines partial status information from multiple sources, such as battery charge and temperature, into a single, visually prominent display, using larger and ring-shaped optical elements that change color or brightness based on relevance, allowing operators to quickly assess operational readiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple partial status output elements are provided to display individual status parameters, then the information completeness is improved, but the device complexity and information overload increase
Solution Approach 1:
The patent combines multiple partial status output elements into a single device status output element that displays an overall status derived from individual status parameters. This merging approach maintains complete information display while reducing interface complexity and preventing information overload.
Solution Approach 2:
The device status output element serves multiple functions: it displays overall device status, indicates operational readiness, and provides derived status information that synthesizes multiple individual status parameters into a single comprehensive indicator.
2Measurement precision
If multiple partial status output elements are provided for detailed status display, then the measurement precision is improved, but the ease of operation deteriorates due to difficulty in quick assessment
Solution Approach 1:
By merging multiple partial status indicators into a single device status output element, the system maintains precise monitoring of individual parameters while enabling quick overall assessment through the derived device status, thus improving ease of operation without sacrificing measurement precision.
Solution Approach 2:
The system performs preliminary synthesis of multiple status parameters into a derived device status that indicates operational readiness in advance, allowing operators to quickly assess whether the tool is ready for operation without needing to interpret multiple individual status indicators.
3Ease of operation
If a device status output element is added to display derived status information, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The device status output element is designed to be multi-functional, serving as both a detailed status display and a simplified operational readiness indicator. This universal design improves ease of operation without requiring additional separate output elements, thus avoiding increased device complexity.
