Innovation Solution
A calculator with a detachable handwriting pad and magnetic attraction elements for folding and unfolding, combined with a button module group and LCD screen for mathematical operations, allowing direct data recording and calculation without separate tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If paper, pen, and calculator are used separately for calculations, then calculation function is achieved, but carrying and storage becomes cumbersome
Solution Approach 1:
The patent combines the calculator and handwriting pad into a single integrated device. The handwriting pad is detachably connected to the calculator body, allowing users to have both functions in one unit. This merging eliminates the need to carry separate paper and pen, directly resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The integrated device provides multiple functions: calculation through the calculator body and handwriting/recording through the detachable handwriting pad. This multi-functionality allows a single device to replace multiple separate tools (calculator, paper, pen), improving carrying convenience while maintaining all necessary capabilities.
2Ease of operation
If paper and pen are carried separately for data recording, then recording function is available, but accessibility becomes inconvenient
Solution Approach 1:
The handwriting pad is integrated with the calculator body through a detachable connection mechanism. This merging ensures that the recording function is always accessible when the calculator is in use, eliminating the need to separately carry and locate paper and pen items.
3Adaptability or versatility
If multiple separate tools are used for calculation and recording, then functional completeness is achieved, but storage becomes inconvenient
Solution Approach 1:
The patent merges the calculator and handwriting pad into a single integrated unit with detachable connection. This combining reduces the total volume of items to carry and store, while maintaining functional completeness through the integrated design that supports both calculation and recording operations.
Solution Approach 2:
The handwriting pad is designed as a detachable segment that can be separated from the calculator body. This segmentation allows for flexible configuration where users can attach the handwriting pad when recording functions are needed and detach it when only calculation is required, optimizing storage space while maintaining functional versatility.
