Solution Overview

Problem

Conventional vehicle storage devices with lock mechanisms suffer from reduced locking certainty due to dimensional variations and positional changes in the lock member and button, leading to compromised security.

Innovation Solution

A vehicle storage device with a lock mechanism that includes a swingable lock member, a biasing member to maintain the lock member in a locked position, a button to release the lock, and a support member with a stopper to restrict the lock member's position, ensuring high locking performance by maintaining the lock member in a predetermined locked position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional lock mechanism with a swingable lock member and button is used, then the device can be manufactured with simple structure, but the locking performance is reduced due to dimensional variations and positional changes

Engineering Contradiction:
Improvelocking performanceVSAvoidlock mechanism structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The lock mechanism is divided into distinct functional components: a lock member for engagement, a button for actuation, and a stopper for positioning. This segmentation allows each component to be optimized independently for its specific function while maintaining overall system reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stopper is pre-positioned on the support member to restrict the lock member's movement to a predetermined range. This preliminary positioning action ensures that the lock member maintains consistent engagement with the lid regardless of dimensional variations in the button or other components.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If dimensional tolerance is allowed in the button and lock member for ease of manufacture, then manufacturing cost is reduced, but locking certainty is compromised

Engineering Contradiction:
Improvedimensional toleranceVSAvoidlocking certainty
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The stopper automatically compensates for dimensional variations in the button and lock member by restricting the lock member's position. This self-adjusting mechanism ensures consistent locking performance without requiring tight manufacturing tolerances, thereby maintaining ease of manufacture while improving reliability.

Inventive Principle:
Principle #25Self-service

3Volume of moving object

If the button is positioned close to the lock member for compact design, then device size is reduced, but locking stability is affected by positional variations

Engineering Contradiction:
Improvelock mechanism sizeVSAvoidlocking stability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The stopper is pre-installed on the support member to establish a predetermined engagement position for the lock member. This preliminary positioning ensures that even in a compact design where the button is close to the lock member, the locking stability is maintained by preventing positional variations during operation.

Inventive Principle:
Principle #10Preliminary action

AI summary

A lock mechanism includes a lock member that can take a locked position in which the lock member contacts a lid to lock the lid, and an unlocked position in which the lock member is spaced apart from the lid to release the locking, a button that pushes the lock member to cause the lock member to swing to the unlocked position, and a support member that supports both the lock member and the button. The support member has a stopper for locking the lock member in the locked position. The stopper is integrated with the support member. The button is spaced apart from the lock member when the lock member is in the locked position.
