Double-Door Display Case Front Door Locking via Rear-Door Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-door display cases lack a controllable front door opening mechanism, often relying on locks that are aesthetically unpleasing and inconvenient for on-site operation.
Innovation Solution
A controllable front door opening structure for a double-door display case, featuring a case body with a rotatable front door, a limiting member connected to the front door, and a locking member that translates or rotates to unlock the limiting member, allowing controlled opening and closing of the front door from the rear door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the front door is provided with a lock to prevent unauthorized opening, then security is improved, but aesthetic appearance deteriorates and operational convenience worsens
Solution Approach 1:
The patent introduces a locking mechanism that is actuated from the rear door rather than requiring direct interaction with a lock on the front door. The locking member (3) serves as an intermediary that can be controlled from inside the display case through the rear door, eliminating the need for visible locks or keys on the front door while maintaining security and improving aesthetics.
2Reliability
If the front door is locked to prevent customer access, then security is improved, but ease of operation deteriorates due to lack of on-site control
Solution Approach 1:
The locking mechanism is designed to be self-controlled from within the display case through the rear door. The locking member (3) can be actuated by the seller or operator from inside the case, providing self-service capability without requiring external keys or remote systems. This maintains security while enabling on-site control when needed.
3Ease of operation
If the front door structure is simplified without locking mechanisms, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The locking member (3) acts as an intermediary mechanism that can be actuated from the rear door to control the limiting member (2) on the front door. This maintains a simple front door appearance without visible locks while providing security control through the internal locking mechanism that engages with the limiting member.

AI summary
A controllable front door opening structure for a double-door display case includes a case body, where a front side of the case body is rotatably connected to a front door; an inner side of the front door is connected to a limiting member; the limiting member rotates synchronously with the front door; a locking member is provided in the case body; the locking member limits rotation of the limiting member; and the locking member translates or rotates to unlock the limiting member. By controlling the locking member at a rear door of the case body to move forward and backward or to rotate, the front door is locked or unlocked.
