Hinged Terminal Case Assembly for Fall-Resistant Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic payment terminal cases face challenges in reducing size while maintaining fall resistance, as increased screw fastenings occupy valuable space and complicate maintenance, and are prone to breakage during falls.
Innovation Solution
Implementing a hinged fastening system between the lower and upper covers using a rotation shaft that allows for secure attachment without additional screws, providing flexibility and locking mechanisms to ensure closure during falls and simplify maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of screws is increased to improve fall resistance, then the case remains closed during falls, but the terminal size increases and space for components is reduced
Solution Approach 1:
The patent applies a hinged fastening system that allows dynamic movement between closed and open positions while maintaining secure closure during falls. The hinge mechanism provides flexibility to absorb impact forces rather than relying on multiple rigid screw connections, thus achieving fall resistance without increasing terminal size.
Solution Approach 2:
The invention extracts the fastening function from traditional screw-based systems and implements it through an integrated hinged mechanism. This eliminates the need for multiple screws while maintaining closure reliability, thereby preserving terminal size and component space.
2Reliability
If the number of screws is increased to improve fall resistance, then the case remains closed during falls, but the dismantling time increases
Solution Approach 1:
The hinged fastening system enables dynamic transition between closed and open states with a single motion, eliminating the need to individually remove multiple screws. This reduces dismantling time significantly while maintaining fall resistance through the hinge's ability to secure the case during impacts.
3Ease of manufacture
If screws are used to fasten covers, then the case can be assembled, but the screw-fastening sleeves are fragile and may break during falls
Solution Approach 1:
The hinged fastening mechanism integrates multiple structural elements into a unified composite system that combines the advantages of rigid fastening with flexible impact absorption. This composite structure eliminates the fragility of individual screw-sleeve components while maintaining assembly capability.
Solution Approach 2:
The hinge mechanism introduces dynamic flexibility to the fastening system, allowing it to adapt to impact forces during falls rather than relying on brittle screw-sleeve connections. This maintains assembly ease while significantly improving fastening durability under stress.

AI summary
A housing of a terminal is formed by at least one lower cover and an upper cover. The housing the lower cover and upper cover are fixed together in an articulated manner, the articulated fixing being able to take up at least one position closing the housing and a position opening the housing, in which the lower cover and upper cover are joined together.
