Optical Detection Floor Stand Layout for Unobstructed Surgical View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor stands for optical detection apparatuses restrict the field of view of surgeons, particularly in medical surgery scenarios, due to their design, which can obstruct the line of sight to monitors and surgical areas, hindering ergonomic working conditions.
Innovation Solution
A floor stand design with a first stand arm length dimensioned to ensure the distance between the base plane and the second joint is smaller than the sum of the maximum seated eye level and lower leg length, allowing for an unobstructed view by positioning the optical detection device below the surgeon's eye level and enabling easy adjustment and positioning over a wide range, with a compact collapse configuration and optional rotary joints for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the stand arms are positioned higher to support the optical detection device, then the device can be properly positioned for optical detection, but the field of view of the surgeon is restricted and the line of sight to monitors is obstructed
Solution Approach 1:
The patent positions the optical detection device in a different spatial dimension by extending it laterally from the stand axis rather than positioning it directly above. The device is mounted on the second stand arm which extends perpendicular to the first stand arm, creating a lateral offset that removes the device from the surgeon's direct line of sight while maintaining optimal optical detection geometry. This dimensional repositioning resolves the contradiction between detection capability and field of view.
2Length of moving object
If the first stand arm is made longer to extend the reach, then the optical detection device can be positioned further from the surgical site, but the distance from the base plane increases and may obstruct the surgeon's view
Solution Approach 1:
The patent divides the stand structure into two distinct arms with different functions: the first stand arm provides vertical support and positioning, while the second stand arm provides lateral extension. This segmentation allows the first arm to remain relatively short (not obstructing view) while the second arm extends the reach laterally to position the optical device optimally. The combined effect achieves the desired reach without the visibility problems of a single long vertical arm.
3Device complexity
If the stand structure is simplified, then the device complexity is reduced, but the ability to adjust and position the optical detection device over a wide range is limited
Solution Approach 1:
The patent incorporates rotary joints at both the first and second stand arms, making the structure dynamically adjustable. The first rotary joint allows the first stand arm to rotate around the vertical axis, while the second rotary joint allows the second stand arm to rotate around the horizontal axis. This dynamic configuration enables the optical detection device to be positioned over a wide range of positions and angles while maintaining a relatively simple two-arm structural design.

AI summary
The invention relates to a floor stand for an optical detection device, having a foot part comprising multiple bearing points or a planar standing surface that span a base plane, having a first stand arm which is pivotably connected to the foot part by a first joint on the foot part, and which is connected to a second stand arm by a second joint remote from the foot part, wherein the length of the first stand arm is dimensioned such that the distance between the base plane and the second joint is smaller than the sum of the maximum value for the eye level when seated and the maximum value for the length of the lower leg including the foot when the first stand arm is aligned at 45 degrees in relation to the base plane.
