Hand Scanner Holder Inversion for Smooth Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing scanner apparatuses, the grasping part of the hand scanner held by the hand scanner holder is positioned below the arms, making it difficult for users to smoothly remove the hand scanner without hitting the holder with their hand or fingers.
Innovation Solution
A hand scanner holder design with a base part that includes a pair of holding pieces forming a recess to hold the lower part of the grasping part, allowing the upper part to protrude, preventing hand or finger contact with the holder during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the grasping part is positioned below the arms in the holder, then the hand scanner can be held securely, but the user's hand or fingers hit the holder during removal
Solution Approach 1:
The patent inverts the conventional holding structure by positioning the grasping part above the arms instead of below. The pair of arms extends upward to support the lower surface of the grasping part, while the upper surface of the grasping part protrudes above the arms. This inversion allows the hand to be grasped above the holder structure, preventing contact with the holder during removal while maintaining secure holding through the arm support.
2Adaptability or versatility
If the grasping part protrudes downward below the arms, then the hand scanner is easily accessible, but it causes difficulty in smooth removal
Solution Approach 1:
The patent applies inversion by changing the protrusion direction from downward to upward. The grasping part protrudes upward above the pair of arms rather than downward below them. This maintains accessibility since the grasping part remains exposed and reachable, while simultaneously enabling smooth removal by positioning it clear of the holder's arm structure.
3Volume of moving object
If the reading unit is tapered with narrower width near the grasping part, then the hand scanner has compact design, but it limits the holding structure configuration
Solution Approach 1:
The patent applies local quality by making the pair of arms asymmetric in length. The first arm extends farther upward than the second arm, creating different support levels on each side. This asymmetric local configuration accommodates the tapered reading unit shape while providing differentiated support zones, allowing the compact hand scanner design to coexist with an optimized holding structure.
