Handheld Tool Display Layout for Tilted Working Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held processing devices, such as chainsaws and angle grinders, face challenges in displaying device states and functions clearly to users when the device is tilted by 45° or more around its longitudinal axis, as existing solutions often obscure the display or require users to turn their head to view it.
Innovation Solution
The display field is arranged offset in the housing circumferential direction relative to the control element, extending over the housing edge and/or with a curved or kinked course, ensuring visibility even when the device is tilted, and featuring non-parallel display surfaces for improved visibility in different working positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display field is arranged in a conventional position on the device housing, then the device structure remains simple, but the display becomes obscured or invisible when the device is tilted by 45° or more around its longitudinal axis
Solution Approach 1:
The display field is arranged to extend in the circumferential direction around the longitudinal axis of the device, transitioning from a conventional flat position to a three-dimensional circumferential arrangement. This allows the display to remain visible across multiple tilted working positions by wrapping around the device housing in the circumferential dimension.
Solution Approach 2:
The display field follows a curved or angled course around the circumferential direction of the device housing, rather than maintaining a straight linear arrangement. This curved configuration ensures that display elements remain within the user's field of view regardless of the device's tilt angle.
2Ease of operation
If the display field and control element are positioned close together for compact design, then the device size is reduced, but the user's view of the display is obstructed when operating the control element
Solution Approach 1:
The display field is positioned offset in the circumferential direction relative to the control element, utilizing the circumferential dimension around the device's longitudinal axis. This spatial separation in the circumferential direction allows both the display and control element to be accessible without mutual obstruction, while maintaining compact overall device dimensions.
3Ease of operation
If the display field extends over the housing edge with a curved course to maintain visibility, then display visibility is improved, but the manufacturing complexity and precision requirements increase
Solution Approach 1:
The display field is divided into multiple discrete optical display elements arranged along the curved or angled course. This segmentation allows each element to be positioned independently with standard tolerances, reducing the cumulative precision requirements compared to positioning a single continuous display surface along a curved path.
Solution Approach 2:
The display field features non-parallel display surfaces with different orientations in different regions. Each local section of the display is optimized for visibility in specific working positions, with surfaces angled or curved to match the expected viewing geometry in those positions.
