Lock Body Single Spring Piston Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock body electric motor arrangements require precise installation of two springs, which is difficult and costly, and can lead to imbalance in spring forces, complicating the assembly and increasing production costs.
Innovation Solution
A single spring is used to replace the two-spring system, with vanes on the piston and counterpart overlapping and surrounded by the spring, allowing the spring to store potential energy and push the piston either outwards or inwards, facilitating easier installation and balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two springs are used in the electric motor arrangement, then the piston can be pushed in both directions, but the installation becomes difficult and costly with potential force imbalance
Solution Approach 1:
The patent combines the functions of two separate springs (pushing piston outward and inward) into a single spring system. The single spring is arranged to act on the piston through a mechanical arrangement that enables bidirectional force application, thereby reducing component count and installation complexity while maintaining the required bidirectional movement capability.
Solution Approach 2:
The single spring performs multiple functions: it provides the outward pushing force on the piston, serves as a structural element in the motor arrangement, and enables bidirectional control through its mechanical linkage. This multi-functional design eliminates the need for separate springs for each direction.
2Ease of operation
If two springs are used in the electric motor arrangement, then the piston can be pushed in both directions, but production costs increase
Solution Approach 1:
The patent merges two separate spring components into a single spring component, directly reducing parts count and associated manufacturing costs. This consolidation eliminates the need for purchasing, storing, and managing two separate spring inventories, thereby reducing production costs.
Solution Approach 2:
The patent extracts one spring from the system, removing the unnecessary component while retaining the essential bidirectional functionality through the redesigned single spring arrangement. This extraction eliminates the cost associated with the redundant spring.
3Ease of operation
If two springs are used in the electric motor arrangement, then the piston can be pushed in both directions, but assembly becomes complicated with precision requirements
Solution Approach 1:
The patent combines two separate spring installation procedures into a single spring installation process. The single spring is designed with features that facilitate easier positioning and securing, reducing the precision requirements and simplifying the assembly process compared to coordinating two separate springs.
4Ease of operation
If two springs are used in the electric motor arrangement, then the piston can be pushed in both directions, but force balance becomes difficult to achieve
Solution Approach 1:
The patent merges the force generation functions into a single spring system where the spring's mechanical arrangement inherently provides balanced forces in both directions. The single spring's design and positioning ensure symmetrical force application, eliminating the difficulty of balancing two separate springs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the assembly process, reduces production costs, and ensures symmetrical action in both directions, making the electric motor arrangement suitable for various lock body types with improved piston travel distance and reduced risk of incorrect installation.
Implementation Method 1
The spring is arranged to store potential energy during a guiding state of the electric motor, wherein the movement of the piston is at least partially impeded, and to push the piston away from or towards the electric motor when the piston is able to move

AI summary
The invention relates to a lock body having an electric motor. The electric motor is arranged to guide the forming and removing of a force transmission connection between the parts to be arranged in the force transmission connection to transfer force or to impede force transfer. If formation of the force transmission connection is not achieved, the construction of the invention is such that the use of one spring enables the pushing of the piston connected to the electric motor both outwards and inwards.
