Sliding Wall Locking Indicator with Color-Coded Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding wall systems lack a clear and user-friendly method to identify the locking state of door leaf elements, making it difficult for users to determine if the door is locked or unlocked.
Innovation Solution
A sliding wall system with a compact locking mechanism and display device that indicates the locking state through a traffic light-like system, using a locking element with three positions and two indicator elements that overlap to show the status, allowing easy recognition of the door's locking state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is provided in the sliding wall system, then the door leaf element can be locked securely, but the locking state cannot be recognized immediately
Solution Approach 1:
The patent uses color-coded indicator elements (first and second indicator elements with different colors) to visually represent different locking states. The first indicator element indicates when the door leaf element is locked against displacement, while the second indicator element indicates when it is locked against pivoting. This color-change visualization resolves the contradiction by making the locking state immediately recognizable without compromising the security function.
Solution Approach 2:
The patent introduces an intermediary display device that mediates between the locking mechanism and the user. This display device includes indicator elements that are actuated by the locking element to provide visual feedback about the locking state. The intermediary translates the mechanical locking state into easily recognizable visual signals, solving the recognition problem while maintaining the reliability of the locking mechanism.
2Reliability
If multiple locking positions are provided for the door leaf element, then comprehensive security control is achieved, but the operation becomes complex
Solution Approach 1:
The patent employs a universal locking element that can assume multiple positions (first position for blocking displacement, second position for blocking pivoting, and potentially combined positions). This single multi-functional locking element replaces what would otherwise require multiple separate locking mechanisms, achieving comprehensive security control while maintaining operational simplicity through a single actuator.
Solution Approach 2:
The patent merges multiple locking functions into a single integrated locking mechanism. The locking element combines the functionality of blocking displacement and blocking pivoting into one component that can be actuated in different positions. This merging reduces the number of separate operations needed while maintaining comprehensive security control across multiple locking states.
3Difficulty of detecting and measuring
If a display device with multiple indicator elements is provided, then the locking state can be clearly identified, but the device complexity increases
Solution Approach 1:
The display device is segmented into distinct functional components: a first indicator element for displacement locking status and a second indicator element for pivoting locking status. Each indicator element is independently actuated by the locking element based on its position. This segmentation allows clear identification of different locking states while keeping each individual indicator element simple in structure.
Solution Approach 2:
The display device operates on a self-service basis where the locking element directly actuates the indicator elements through its own movement. As the locking element moves to different positions, it automatically triggers the corresponding indicator elements to display the current locking state without requiring additional actuators or complex control mechanisms. This self-actuation reduces device complexity while maintaining clear state identification.
