Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional push-button devices or touchscreen kiosks are used for feedback collection, then user input can be captured, but hygiene risks increase due to direct contact surfaces and cost increases
Solution Approach 1:
The patent replaces traditional mechanical push-buttons and touchscreen interfaces with foot-operated pedals that activate sensors. This substitution eliminates direct hand contact with feedback collection surfaces, thereby reducing hygiene risks while maintaining reliable feedback capture capability through alternative mechanical input methods
Solution Approach 2:
The patent introduces foot pedals as an intermediary device between the user and the feedback collection system. This intermediary allows users to provide input without directly touching the main device surface, effectively breaking the transmission path for contaminants while preserving the core functionality of collecting user feedback
2Reliability
If conventional feedback systems are deployed, then feedback can be collected, but material sustainability deteriorates due to non-recyclable components
Solution Approach 1:
The patent designs the feedback station housing and pedal components to be easily disassembled and recycled. By using recyclable materials and avoiding permanent adhesives or complex fastening systems, the system enables recovery and reuse of materials after the device's service life, directly addressing material sustainability concerns while maintaining functional reliability during use
Solution Approach 2:
The patent divides the feedback station into modular components that can be separately manufactured, assembled, and recycled. This segmentation allows each component to be optimized for its specific function while facilitating easier disassembly and material recovery at end-of-life, resolving the conflict between functional reliability and material sustainability
3Ease of operation
If pedals are exposed for direct use, then user input is accessible, but user anonymity is compromised due to lateral visibility of actions
Solution Approach 1:
The patent positions the pedals and their support structure asymmetrically within the housing, specifically designing them to be visible only from the front viewing angle. This asymmetric arrangement allows users to operate the pedals easily from the front while preventing lateral observation of which pedal is pressed, thereby preserving user anonymity without compromising operational ease
Solution Approach 2:
The patent employs the housing structure as a visual shield, using its walls to block lateral lines of sight to the pedals. This creates a visual privacy zone where pedal actions cannot be observed from side angles, maintaining user anonymity while keeping the pedals fully accessible from the front for easy operation
4Reliability
If computing devices are securely housed, then device protection is improved, but device removal flexibility decreases due to permanent fasteners
Solution Approach 1:
The patent implements a dynamic fastening system using reversible adhesive elements that can be easily applied and removed without permanent damage. This allows the computing device to be securely held during operation (improving reliability) while enabling straightforward removal and replacement when needed (maintaining operational flexibility), avoiding the commitment of permanent fasteners

AI summary
A recyclable feedback station comprising a cardboard housing (1) with one or more foot-operated pedals (3) encapsulated within the housing to collect user input in a hygienic and anonymous manner. Encapsulation (5) prevents direct contact with internal components while ensuring actuation is visible from the front but concealed laterally for user privacy. The housing (1) includes a stabilizing base (FIG. 3) configured to resist tilting during repeated use and may be shipped flat-packed for efficient transport. A compartment (4) may securely house a computing device (2), such as a tablet, the compartment being configured to accommodate devices of varying sizes including reused or heterogeneous tablets, thereby supporting sustainability. The compartment (4) is assembled without glue or bolts. The device (2) may include an integrated alarm system to prevent unauthorized removal. The station supports deployment across industrial, healthcare, service, and retail environments for sustainable and anonymous feedback collection.
