Microscope Gripping Portions for Safe Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional microscope apparatuses are heavy and difficult to move due to their rigid metal construction, and existing handling mechanisms are not intuitive or safe for beginners, often leading to accidents during handling and observation.
Innovation Solution
A microscope apparatus with two arms extending from the stand portion, featuring gripping portions on their lower surfaces that are designed to be easily recognizable and gripped by an observer, allowing for safe and comfortable handling with both hands, while preventing collisions with the objective lens and stage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the microscope apparatus is made with rigid metal construction to ensure clear image observation, then the rigidity and image quality are improved, but the weight increases and the apparatus becomes difficult to move
Solution Approach 1:
The microscope apparatus is divided into multiple components (base, stand, arm, optical system) that can be supported and moved using body mechanics. The arm portion acts as a separate segment that extends from the stand, allowing the user to distribute the weight across different body parts during movement.
Solution Approach 2:
The patent introduces holding units with finger hooks as intermediary elements between the user's hands and the microscope apparatus. These finger hooks provide secure grip points that facilitate easy movement despite the apparatus's weight, acting as a mediator that reduces the effort required to move the rigid metal construction.
2Ease of operation
If finger hooks are disposed on lower surfaces of protrusion portions and base to provide holding units, then the apparatus can be held, but beginners may not recognize the handle and the microscope may fall down when inclined
Solution Approach 1:
The finger hooks are colored differently from the surrounding components to make them visually prominent and easily recognizable. This color differentiation ensures that beginners can quickly identify the correct gripping positions without confusion, improving both ease of operation and safety.
Solution Approach 2:
The finger hooks are pre-positioned on the arm portion at optimal locations that ensure stable handling from the beginning. By placing the hooks on the arm portion rather than the base, the design preliminarily establishes a grip position that prevents the microscope from falling when inclined, eliminating the need for users to learn proper handling techniques.
3Ease of operation
If a large recessed portion is provided on the interior surface of the microscope arm for gripping, then the observer can grip the apparatus, but the gripping position is not fixed and may cause collision with objective lens or stage
Solution Approach 1:
Instead of providing one large recessed portion, the patent segments the gripping area into multiple discrete finger hooks positioned at specific locations on the arm portion. This segmentation fixes the gripping position, guiding users to hold the apparatus at the correct location and preventing fingers from extending too far forward where they could collide with the objective lens or stage.
Solution Approach 2:
The finger hooks are strategically positioned at specific locations on the arm portion where they provide optimal grip without interfering with other components. The local quality of the arm portion is enhanced by adding these discrete gripping elements at precise locations, ensuring safe handling while maintaining clear access to the objective lens and stage areas.
