Integration of a laser measuring system within handheld power tools, including a rotatable and stationary laser apparatus, processing circuitry, and a display, allowing for single-handed operation and precise distance measurements without additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measuring devices are used for positioning hand held power tools, then measurement capability is provided, but device complexity and ease of operation deteriorate due to requiring multiple separate equipment
Solution Approach 1:
The patent combines the laser measuring system with the hand held power tool into a single integrated device. The laser apparatus is mounted on the power tool body, allowing the tool to simultaneously perform both power operations and distance measurements without requiring separate measuring equipment.
Solution Approach 2:
The hand held power tool is designed to perform multiple functions: it can execute power tool operations and simultaneously function as a measuring device with laser distance measurement capabilities, eliminating the need for specialized separate measuring instruments.
2Measurement precision
If separate measuring devices are used for positioning hand held power tools, then measurement capability is provided, but productivity deteriorates due to requiring craftsmen to set down one equipment to operate another
Solution Approach 1:
The laser measuring system is integrated into the hand held power tool, allowing continuous operation of both the power tool and measuring functions without interruption or equipment switching, thereby maintaining productivity.
Solution Approach 2:
The integrated design enables the craftsman to continuously use the power tool for its primary function while simultaneously utilizing the laser measuring system for positioning and measurement tasks without breaking the workflow.
3Measurement precision
If traditional distancing methods are attached to hand held power tool, then measurement capability is added, but ease of operation deteriorates due to inconsistent coordinate systems and poor integration
Solution Approach 1:
The laser measuring system is permanently integrated into the hand held power tool body with fixed mounting positions, creating a unified coordinate system that is consistent throughout operation, unlike attachable methods that may have alignment issues.
Solution Approach 2:
The system provides real-time distance measurements displayed on the tool's display unit, giving immediate feedback to the craftsman about positioning accuracy and enabling precise control during operation.

AI summary
The present disclosure relates to powered hand tools with a laser measuring system to measure a distance between a tool and a reference surface. The hand held power tool includes a rotatable distancing laser disposed within a rotatable laser housing that is coupled to a body such that a laser beam emitted from the rotatable distancing laser is emitted in a plane parallel to a plane of an axis of rotation of the chuck, and a stationary distancing laser disposed within a handle of the hand held power tool and arranged such that a laser beam emitted from the stationary distancing laser is orthogonal to the emitted laser beam of the rotatable distancing laser.
