Torque Tool Head-Up Display for Real-Time Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional torque tools are cumbersome and difficult to use effectively, especially with new lightweight materials in the automotive and aircraft industries, as they require precise torque application without distracting the user from their work, and existing digital displays can be hard to read, especially in confusing environments.
Innovation Solution
A head-up display system for torque tools that projects information directly in the user's line of sight using a projector and transparent projection surface, allowing hands-free operation and real-time data access without needing integrated displays, with optional voice control and acoustic signals for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an integrated digital display is incorporated into the torque tool housing, then torque data can be displayed, but the tool becomes heavier and more complex
Solution Approach 1:
The display function is extracted from the torque tool housing and implemented as a separate head-up display system. The controller in the housing transmits torque data wirelessly to a separate display device, eliminating the need for integrated display components and reducing tool complexity while maintaining full torque data visibility.
Solution Approach 2:
A wireless transmission system acts as an intermediary between the torque tool controller and the head-up display device. This mediator enables data communication without physical integration, allowing the tool to remain simple while providing comprehensive torque information through the separate display system.
2Loss of information
If a traditional display unit is integrated into the torque tool, then torque information is available, but the user's attention is diverted from the workpiece
Solution Approach 1:
The display is moved from a two-dimensional surface in the user's periphery to a three-dimensional virtual image in the user's direct line of sight. This dimensional change allows torque information to be viewed without shifting visual focus from the workpiece, as the head-up display projects information into the user's field of view rather than requiring lateral attention shifts.
3Weight of moving object
If lightweight materials are used in construction, then component weight is reduced, but the screw connections become more sensitive to torque errors
Solution Approach 1:
The system continuously monitors torque application in real-time and provides immediate visual feedback through the head-up display. This feedback mechanism allows users to adjust their torque application technique on-the-fly, ensuring precise control when working with lightweight materials that have lower tolerance for torque errors, thereby maintaining reliability despite weight reduction.
