Polycarbonate Price Sheet Holder With Double-Bend Tongue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional polycarbonate price display boards are limited in height and cannot securely hold larger or heavier advertising materials, leading to readability issues and poor aesthetics when used with digital, radio-controlled electronic price tags or other heavy objects.
Innovation Solution
The polycarbonate display board design is enhanced by bending the tongue and carrier plate multiple times to achieve better tension against the windshield, and a temperature-resistant clamping rail is added for advertising text, allowing for flexible material choices and printing options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the carrier plate is made larger to provide more advertising space, then the advertising area is improved, but the carrier plate lifts off the pane and hangs down into the vehicle interior, making the price sheet unreadable and optics unappealing
Solution Approach 1:
The patent implements a multi-level nesting structure where the carrier plate is bent twice to create nested folds: the first bend creates a tongue that inserts into the ventilation slot, and the second bend creates a support surface that nests against the pane. This nested configuration allows the large carrier plate to maintain stability by nesting its functional elements within the limited space between the pane and vehicle interior, preventing it from hanging down while preserving the full advertising area.
Solution Approach 2:
The patent transitions from a conventional single-bend design to a double-bend configuration, adding a new dimensional element to the structure. The first bend operates in one plane to create the insertion tongue, while the second bend operates in a different plane to create the support surface. This dimensional change enables the carrier plate to achieve stability in three-dimensional space without reducing its advertising area.
2Weight of moving object
If the carrier plate is made heavier to support digital price displays, then the load-bearing capacity is improved, but the carrier plate lifts off the pane and cannot be read well
Solution Approach 1:
The double-bend nested structure allows the heavy carrier plate to maintain position stability by nesting the tongue and support surface within the ventilation slot and against the pane. The nested configuration distributes the weight of digital price displays along the bent structure, with the first bend providing insertion stability and the second bend providing support surface stability, preventing the entire plate from lifting off.
Solution Approach 2:
The patent segments the carrier plate into functionally distinct parts through double bending: the tongue portion for insertion, the bent section for structural support, and the support surface for displaying heavy objects. This segmentation allows each part to perform its specific function optimally, with the bent sections acting as structural elements that distribute and bear the weight of digital price displays without causing the entire plate to lift.
3Stability of the object's composition
If aluminum composite material is used instead of polycarbonate to avoid lifting, then the position stability is improved, but the cost and processing complexity increase many times
Solution Approach 1:
The patent changes the geometric parameters of the polycarbonate carrier plate by introducing a second bend, transforming it from a single-bend to a double-bend structure. This parameter change modifies the mechanical behavior of the polycarbonate, enabling it to achieve position stability comparable to aluminum composite materials while maintaining the advantages of polycarbonate such as lower cost, easier processing, and simpler manufacturing.
Solution Approach 2:
The patent segments the carrier plate structure into distinct functional zones through double bending, creating a tongue portion and a support surface portion. This segmentation allows the polycarbonate material to be optimized for each function: the tongue for insertion and the bent sections for structural support. This structural segmentation enables polycarbonate to achieve the position stability previously requiring aluminum composite, while maintaining manufacturing simplicity and cost-effectiveness.

AI summary
The invention relates to a system for price labeling of motor vehicles made of polycarbonate. This polycarbonate price label consists of a carrier plate (1) and a tongue (5) which is, for example, clamped into the ventilation slot of the windshield and, unlike conventional polycarbonate price labels, is not bent once but twice or more in order to be pressed directly against the windshield even with larger polycarbonate carrier plates with more weight and/or carrier plates with price radio displays.
