ATM Valuables Box Double Wall Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valuables containers, such as banknote containers for ATMs, lack adequate protection against external manipulation and mechanical stability, particularly with safety-relevant control means located on the base part's wall.
Innovation Solution
A double wall structure is created by welding at least one wall of the base part to a facing wall, which encloses the control means, enhancing protection against manipulation and mechanical stability, with the facing wall designed to cover the edge section of the cover part to prevent unauthorized access and using ultrasonic welding for a stable and economical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control means are located on the wall of the base part for easy access and operation, then ease of operation is improved, but protection against external manipulation deteriorates
Solution Approach 1:
The control means are nested within a double wall structure, where the facing wall is positioned between the external environment and the control means on the base part wall. This nesting arrangement allows operational access while providing protective enclosure against external manipulation attempts.
Solution Approach 2:
The protection is achieved by adding a spatial dimension - the facing wall creates a new layer in the structural arrangement. Instead of merely protecting the control means on the existing wall surface, a third dimension (depth) is introduced by positioning the facing wall parallel to and facing the base part wall, thereby enclosing the control means in a protected space.
2Object-affected harmful factors
If a double wall structure is created by welding a facing wall to the base part wall for protection, then protection against manipulation is improved, but device complexity increases
Solution Approach 1:
The protective structure is segmented into distinct functional components: the base part wall forming the container boundary and the facing wall forming the protective barrier. This segmentation allows each wall to be optimized independently for its specific function while maintaining overall structural integrity through controlled joining at edges.
Solution Approach 2:
The facing wall serves multiple functions simultaneously: it acts as a protective barrier against manipulation, provides structural reinforcement to the base part, and creates the enclosed space necessary for protecting the control means. This multi-functionality reduces the need for additional separate protective components.
3Object-affected harmful factors
If the facing wall covers the edge section of the lid part to prevent unauthorized access, then protection against manipulation is improved, but ease of operation deteriorates
Solution Approach 1:
The facing wall is designed with dynamic characteristics that adapt to different operational states: during normal operation, it provides fixed protection by covering the lid edge; during authorized maintenance or refilling operations, the lid can be removed despite the facing wall presence, as the design anticipates and accommodates this temporary disruption of the protective configuration.
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
The double wall structure effectively protects the control means from external intervention and increases the mechanical stability of the valuables container, making it difficult to tamper with or open without detection, while allowing for assembly-friendly protection and tolerance compensation.
Implementation Method 1
the facing wall is connected to the wall of the base part by ultrasonic welding
