Steering Lock Cover Inclined Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional steering lock devices lack reliability in ensuring the holding member is in the correct position, requiring careful handling and no external confirmation, leading to potential malfunctions and security issues.
Innovation Solution
A steering lock device with an auxiliary lock mechanism featuring a cover and frame with a rod guide hole, an auxiliary engagement portion, and a holding member fixed to the cover, where the inclined portion on the frame and inclination receiving portion guide the cover's positional shift, ensuring reliable activation without complicating the configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holding member is not fixed to the cover but relies on assembly position, then the device structure is simpler, but the reliability of the holding member position is insufficient and external confirmation is required
Solution Approach 1:
The holding member is pre-fixed to the cover in the preliminary assembly stage, ensuring it is always in the correct position before the cover is assembled to the frame. This preliminary positioning action eliminates the need for external confirmation during operation and ensures reliable engagement with the auxiliary lock member.
Solution Approach 2:
The cover serves as an intermediary component that carries the holding member. By fixing the holding member to the cover, the system uses the cover as a mediator to ensure the holding member's position is maintained throughout assembly and operation, resolving the reliability issue without complicating the overall mechanism.
2Ease of operation
If the holding member position cannot be externally confirmed, then the device structure is simpler, but the handling requires careful attention and potential malfunctions occur
Solution Approach 1:
The holding member is pre-positioned and fixed to the cover during manufacturing, ensuring correct positioning before the product reaches the user. This preliminary action eliminates the need for users to carefully verify positions during handling, making operation simpler while ensuring reliability.
3Reliability
If the cover can move freely relative to the frame, then the assembly is easier, but erroneous activation of the auxiliary lock mechanism may occur
Solution Approach 1:
The connection between the cover and frame is designed with localized engagement features: the holding member on the cover engages with the auxiliary lock member on the frame at a specific location. This localized quality ensures the cover cannot move freely and triggers the auxiliary lock only under intended conditions, preventing erroneous activation without requiring complex connection mechanisms throughout the entire structure.
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
The solution enhances reliability by eliminating the need for external confirmation of the holding member's position, simplifying handling, and ensuring secure activation of the auxiliary lock mechanism, preventing erroneous activation and enhancing security against illegal unlocking attempts.
Implementation Method 1
the slide plate 104 is urged in a direction of the lock member 102 by the spring member 111a
Implementation Method 2
By the spring member 111b, the holding shaft 113 is urged in a direction of being spaced apart from the slide plate 104
Implementation Method 3
a lock member 102 that is urged in a direction (upward direction of FIG. 1) of a steering shaft (not shown) of an automobile by a coiled spring 101

AI summary
On at least either one of an inside of an opening edge of a cover (2) and an outside of an opening edge of a frame (3), an inclined portion (95) is formed, and on the other of the inside of the opening edge of the cover (2) and the outside of the opening edge of the frame (3), an inclination receiving portion (96) is formed. In such a way, in an event where external force is applied to the inclined portion (95) from an outside, the inclination receiving portion (96) slides on the inclined portion (95), and positionally shifts or falls off the cover (2).
