Food Shield Single-Sided Locking for One-Person Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food shields require simultaneous adjustment of locking mechanisms on both sides, making it difficult for a single person to adjust the angular disposition of the transparent panel, often necessitating two individuals due to the wide width of the panels.
Innovation Solution
A food shield design featuring a locking mechanism on one lateral side and a non-locking mechanism on the other, allowing the transparent panel to be adjusted and locked angularly from only one side, utilizing a pull collar with a compression spring and detents to facilitate easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking mechanisms are provided on both sides of the transparent panel, then the panel can be securely locked in position, but the adjustment process becomes difficult for a single person to perform
Solution Approach 1:
The locking function is extracted from both sides and concentrated on only one side. The locking mechanism assembly is provided exclusively on one lateral side of the transparent panel, while the opposite side has no locking mechanism. This allows a single person to perform adjustment operations easily while maintaining secure locking capability through the centralized locking assembly on one side.
2Object-affected harmful factors
If the transparent panel width is increased to provide adequate barrier coverage, then contamination prevention is improved, but the adjustment process requires two persons
Solution Approach 1:
The locking function is extracted from both sides and concentrated on only one side. The locking mechanism assembly is provided exclusively on one lateral side of the transparent panel, while the opposite side has no locking mechanism. This allows a single person to perform adjustment operations easily while maintaining secure locking capability through the centralized locking assembly on one side.
3Adaptability or versatility
If locking mechanisms are placed on both sides of the panel, then angular disposition can be controlled, but simultaneous adjustment from both sides is required
Solution Approach 1:
The locking function is extracted from both sides and concentrated on only one side. The locking mechanism assembly is provided exclusively on one lateral side of the transparent panel, while the opposite side has no locking mechanism. This allows a single person to perform adjustment operations easily while maintaining secure locking capability through the centralized locking assembly on one side.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables single-sided adjustment of the transparent panel's angle, simplifying the process and reducing the need for two-person operation, while maintaining effective contamination prevention and customer access.
Implementation Method 1
A pull collar which is biased by a compression spring in a direction towards the end face of the chamber barrel includes a locating pin mounted thereon

AI summary
A food shield for use in a restaurant or food service institution includes a transparent panel, a locking, panel support assembly and a non-locking, panel support assembly. The locking, panel support assembly is mounted on a first vertical support member, and the non-locking, panel support assembly is mounted on a second vertical support member. A first lateral side portion of the transparent panel is affixed to the locking, panel support assembly, and an opposite second lateral side portion of the transparent panel is affixed to the second lateral side portion of the transparent panel. The transparent panel is adjustable in a plurality of angular dispositions, and is locked in one of the angular dispositions by the locking, panel support assembly, and is not locked in one of the angular dispositions by the non-locking panel support assembly.
