Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angle measuring devices are inconvenient for measuring and correcting horizontal and vertical angles as they can only be read from one side and lack functionality to operate in dark environments.
Innovation Solution
A double-sided readout pointer type angle measuring device with integrated LED lighting, featuring a shell with transparent covers, a rotating pointer, and an LED lighting unit with a microcomputer processor and flexible circuit board for automatic lighting and energy-saving features, allowing simultaneous reading from both sides and operation in low light conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pointer type angle measuring device uses single-sided readout design, then the device structure is simple, but the convenience of measurement and correction is poor
Solution Approach 1:
The patent transitions from single-sided readout to double-sided readout by adding a rear transparent cover with dial scale and pointer visible from the back, enabling measurement from both front and rear sides simultaneously. This dimensional expansion resolves the contradiction by maintaining relatively simple structure while significantly improving measurement convenience.
2Adaptability or versatility
If the pointer type angle measuring device lacks lighting function, then the device structure is simple, but the ability to measure in dark environment is poor
Solution Approach 1:
The patent implements a lighting system that automatically activates when the device is tilted beyond horizontal or vertical positions, using the device's own tilt detection to trigger illumination. This self-service approach improves dark environment adaptability while minimizing additional complexity by leveraging the device's existing inclination detection capability.
3Adaptability or versatility
If the pointer type angle measuring device adds double-sided readout and lighting functions, then the convenience and adaptability are improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single device: double-sided angle measurement, inclination detection, automatic lighting control, and level indication. By making the device universal and multi-functional, it improves measurement adaptability while managing complexity through functional integration rather than separate devices.
Solution Approach 2:
The patent combines the lighting function with the inclination detection mechanism, where the same tilt sensing that determines measurement angles also triggers the lighting system. This merging of functions improves adaptability to dark environments while reducing overall device complexity by sharing components and control logic.
