Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvemeasurement capabilityVSAvoidoperational efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #20Continuity of useful action

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

Engineering Contradiction:

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.
