Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bolt housings have complex constructions for decoupling and recoupling the handle and bolt, and this process is only possible in specific positions, making them prone to damage from excessive force and limiting their suitability for electrical operation.
Innovation Solution
A bolt housing with a simplified design featuring an abutment that can be moved between two positions using a coupling-decoupling organ, allowing decoupling and recoupling across a broader range of positions with minimal force, and incorporating a spring and cam mechanism for easy operation, along with a second abutment for enhanced security against burglary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex construction is used for decoupling and recoupling the handle and bolt, then the bolt housing can function as both latch-bolt and dead-bolt, but the device complexity increases and the operation is limited to specific positions
Solution Approach 1:
The bolt housing is divided into functionally independent components: a first organ (spring) for pushing the bolt head, a second organ (follower) for moving the bolt, and a coupling-decoupling organ (cam mechanism) for switching between modes. This segmentation allows each component to perform its specific function with simple construction, eliminating the need for complex integrated mechanisms while maintaining dual functionality.
Solution Approach 2:
The coupling-decoupling organ acts as an intermediary mechanism that switches the connection state between the handle and bolt. By using a cam mechanism with defined positions, it mediates between the latched and unlatched states, enabling versatile operation without requiring complex direct coupling mechanisms.
2Device complexity
If the decoupling and recoupling is limited to specific positions, then the construction can be simpler, but the ease of operation deteriorates and the risk of damage from excessive force increases
Solution Approach 1:
The coupling-decoupling organ incorporates a cam mechanism that dynamically transitions between defined positions. The cam profile is designed to guide the follower through smooth transitions, allowing the system to adapt its mechanical state based on operational needs while maintaining structural simplicity. This dynamic approach enables operation from various positions without compromising construction simplicity.
3Reliability
If the bolt housing is exposed to excessive force during misuse, then the reliability decreases, but adding protective mechanisms increases device complexity
Solution Approach 1:
The first organ (spring) and abutment are pre-configured to resist excessive forces before they can cause damage. The spring provides continuous counteracting force, and the abutment creates a mechanical stop that prevents the bolt from being forced beyond its designed travel range. This preliminary protective action occurs automatically during normal operation, eliminating the need for additional protective devices.

AI summary
The invention relates to a bolt housing which - comprises a bolt that can be operated with a handle, said bolt being able to function both as a latch-bolt and as a dead bolt, wherein the bolt can be in a first terminal position wherein the bolt is brought maximally outside the bolt housing and in a second terminal position wherein the bolt is brought maximally within the bolt housing, wherein the bolt housing - comprises a first organ for the pushing in a direction of the second terminal position towards the first terminal position; and the bolt comprises an abutment which abutment - can be in a first position of the abutment wherein the bolt can be moved from the first position of the bolt to the second position of the bolt; and - can be in a second position of the abutment wherein the bolt can not be moved from the first position of the bolt to the second position of the bolt; wherein the bolt housing is designed for keeping the abutment in the first position of the abutment when the abutment is in the first state and for the keeping in the second position of the abutment when the abutment is in the second state; and the bolt housing further has a coupling-decoupling organ for moving the abutment from the first position of the abutment to the second position of the abutment and vice versa.
