Solution Overview

Problem

Existing lock holders face challenges in achieving precise and easy alignment due to manufacturing tolerances, wear, and deformation, limiting uniform sealing contact pressure and requiring complex adjustments with discrete spacers and laborious reassembly.

Innovation Solution

A lock holder with an adjustable device that allows continuous adjustment of the rear grip's distance from the frame or closing element without detaching the base element, enabling precise alignment and contact pressure control through transverse movement and a guide system for secure guidance and force transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If spacers are used to align the rear handle, then alignment is achieved, but the process becomes time-consuming and requires detaching and reattaching the base element

Engineering Contradiction:
Improvealignment precisionVSAvoidadjustment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The invention replaces static spacers with a dynamic adjusting device that allows continuous modification of the distance between the rear handle and base element. The adjusting device includes an adjusting element that can be rotated to change the distance, enabling dynamic adaptation without detachment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjusting device changes the parameter of distance between the rear handle and base element from a fixed value (determined by spacer thickness) to a continuously variable parameter. This allows precise alignment adjustment by rotating the adjusting element to achieve the optimal distance.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If discrete spacers are used for alignment, then adjustment is possible, but continuous adjustment is limited and reassembly is required

Engineering Contradiction:
Improveadjustment rangeVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjusting device is segmented into multiple functional elements: a base element, an adjusting element with threaded engagement, and a rear handle. This segmentation allows independent adjustment of the distance parameter while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjusting element acts as an intermediary between the base element and the rear handle. It provides a mechanical interface that translates rotational movement into linear distance adjustment, enabling continuous modification without requiring disassembly of the entire assembly.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If the base element is detached to attach spacers, then alignment adjustment is possible, but laborious reassembly is required

Engineering Contradiction:
Improvealignment precisionVSAvoidadjustment ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The adjusting device enables self-service adjustment of the alignment without requiring external intervention or disassembly. The operator can directly rotate the adjusting element to modify the distance, making the system self-adjusting and eliminating the need for laborious reassembly operations.

Inventive Principle:
Principle #25Self-service

4Measurement precision

If spacers of fixed thickness are used, then alignment in incremental steps is achieved, but consistent distance and contact pressure are limited

Engineering Contradiction:
Improvedistance consistencyVSAvoidadjustment flexibility
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The adjusting device transforms the static distance determination (by fixed spacer thickness) into a dynamic adjustment process. The threaded engagement of the adjusting element allows continuous modification of the distance, enabling precise control of both distance and contact pressure without manufacturing constraints.

Inventive Principle:
Principle #15Dynamics
