Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock and bolt systems face issues with inaccurate fitting between doors and frames, leading to difficulties in engaging the bolt and lock, and lack efficient electrical monitoring of the locked state, with existing solutions being complex and prone to damage or costly implementation.
Innovation Solution
A locking device with a bolt part and a lock part featuring a longitudinal guiding device and a transverse guiding device with spring means, allowing for transverse adjustment of the bolt to compensate for fitting inaccuracies and enable easy electrical monitoring of the locked state, using a sliding member and guide rail configuration that can be attached to various door and frame profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bolt receiver is widened to compensate for fitting inaccuracies, then the bolt can engage more easily, but electrical monitoring of the locked state becomes difficult to realize
Solution Approach 1:
The patent replaces complex electrical monitoring systems with a simple mechanical solution. The bolt receiver's longitudinal slot works together with a guide rail and sliding member to provide mechanical guidance and alignment, eliminating the need for complex electrical sensors and wiring while maintaining reliable locked state indication through the mechanical engagement itself
Solution Approach 2:
The bolt receiver is designed with multi-functionality: it not only receives the bolt but also provides longitudinal guidance through its slot, accommodates the sliding member for transverse adjustment, and enables mechanical alignment. This multi-functional design simplifies the overall system by combining several functions into a single component, making electrical monitoring easier to implement
2Manufacturing precision
If a trimming screw is used to adjust and fix the bushing position, then alignment between bolt and bushing is achieved, but the screw represents an exposed part that is easily damaged
Solution Approach 1:
The patent extracts the adjustment function from an exposed trimming screw and integrates it into the guiding device structure. The longitudinal guiding device with its slot and the transverse guiding device with sliding members provide built-in adjustment capabilities that are protected within the locking device housing, eliminating vulnerable external adjustment screws
Solution Approach 2:
The guiding devices are nested within the locking device structure. The longitudinal guiding device is integrated into the bolt receiver, and the transverse guiding device with sliding members is accommodated within the same assembly, creating a compact, protected structure where adjustment mechanisms are not exposed to external damage
3Adaptability or versatility
If a slidable bushing with trimming screw is used to compensate for distance deviations, then alignment is achieved, but an electrical monitoring of the locked state can be realized only with large expenditure
Solution Approach 1:
The patent replaces expensive electrical monitoring systems with a simple mechanical guidance system. The longitudinal slot in the bolt receiver and the guide rail with sliding members provide automatic mechanical alignment and position indication, eliminating the need for complex electrical sensors, wiring, and control systems while maintaining adaptability to distance deviations
4Manufacturing precision
If the clearance between bolt and receiving opening is reduced for precise applications, then locking precision is improved, but fitting inaccuracies cause the bolt to jam
Solution Approach 1:
The patent introduces dynamic adjustment capabilities through the longitudinal guiding device with its slot and the transverse guiding device with sliding members. These mechanisms allow the bolt or receiving opening to adjust their relative positions dynamically, compensating for manufacturing inaccuracies while maintaining small clearance for precise locking when properly aligned
Solution Approach 2:
The guiding devices act as intermediaries between the bolt and receiving opening. The longitudinal slot and transverse guide rail with sliding members provide intermediate adjustment stages that accommodate manufacturing tolerances, allowing the final engaging surfaces to maintain precise alignment with small clearance while the guiding mechanisms absorb the positioning variations
